    1. Shell plant nicht mehr, seine Öl-Produktion bis 2030 wenigstens um 1-2% pro Jahr zu reduzieren. Zwischen 2023 und 2035 will die Firma jährlich 40 Milliarden Dollar in die Öl-und Gasproduktion und 10-15 Milliarden in „Low-Carbon“-Produkte investieren. Die Ölproduktion soll bis 2030 stabil bleiben, die Gasproduktion ansteigen. Shell beruft sich auch darauf, dass man 2021 die Anteile an einem Projekt im Permian Basin verkauft und damit die Ölproduktion früher als geplant bereits gedrosselt habe. https://www.theguardian.com/business/2023/jun/14/shell-drops-target-to-cut-oil-production-as-ceo-guns-for-higher-profits

    1. An der mexikanischen Westküste entsteht mit "Costa Azul" für 2 Milliarden Dollar das erste Terminal für den Export von texanischem Gas nach Asien. Es signalisiert eine weitreichende und für die Dekarbonisierung möglicherweise katastrophale Verschiebung im Gasgeschäft. Die USA könnten zunehmend auch zum Lieferanten für Asien werden. Ob weitere Terminals errichtet werden, hängt von der Klimapolitik der US-Regierung ab, die gerade ein Moratorium für LNG-Terminals ausgerufen hat. https://www.nytimes.com/2024/02/13/climate/mexico-natural-gas-biden.html

    1. Given that neurobiological context, it’s hard to argue that an out-of-school suspension will do much to improve that student’s ability to self-regulate.

      Yes, solution does not help to address underlying issues and makes for more problems - academic ones.

    2. Talking back and acting up in class are, at least in part, symptoms of a child’s inability to control impulses, de-escalate confrontations, and manage anger and other strong feelings — the whole stew of self-regulation issues that can usually be traced to impaired executive-function development in early childhood.

      Identifies some of the behaviors that results from an inability to self-regulate

    3. And suspension rates are substantially higher among certain demographic groups

    4. In reality, though, many schools and school systems look at students who are struggling in those areas and instead think: How do we discipline them?

      Based on your SL experiences, do you agree that most schools prioritze discipling rather than helping kids to attach, bond, deal with stress, and self-regulate?

      During shmita, the land is left to lie fallow and all agricultural activity, including plowing, planting, pruning and harvesting, is forbidden by halakha (Jewish law).

      The sabbath year (shmita; Hebrew: שמיטה, literally "release"), also called the sabbatical year or shǝvi'it (שביעית‎, literally "seventh"), or "Sabbath of The Land", is the seventh year of the seven-year agricultural cycle mandated by the Torah in the Land of Israel and is observed in Judaism.

      Some related ideas that are suggesting some sort of thesis for improving the idea of ungrading: - We measure the things we care about. - In Education, we care about learning and understanding, but measuring these outside of testing and evaluation is difficult at best (therefor ungrading). - No one cares about your GPA six months after you graduate. - Somehow we've tied up evaluations and grades into the toxic capitalism and competition within US culture. Some of this is tied into educational movements related to Frederick Winslow Taylor and Harvards Eliot. - Hierarchies instituted by the Great Chain of Being have confounded our educational process.

    1. Instructive quotations: Who doesn’t love a great quote? And quotations can work very well in a media environment that privileges brevity and catchiness. On the surface, the words of a past leader might seem explanatory for a topical news story, but dig a little deeper into the quote’s original setting, and the particularities—who said it, when, and for what purpose—might make the saying less apt.

      Often instructive quotations aren't appropriate for the current situation because they have been stripped of their original context which doesn't apply to the new situation in which it is being used.

    1. Data Policy and related materialsometimes, on the contrary, demonstrate an oversupply of very high level, generalised information atthe expense of a more concise and meaningful delivery of the essential information necessary for thedata subject to understand the processing being undertaken and to exercise his/her rights in ameaningful way. Furthermore, while Facebook has chosen to provide its transparency information byway of pieces of text, there are other options available, such as the possible incorporation of tables,which might enable Facebook to provide the information required in a clear and concise manner,particularly in the case of an information requirement comprising a number of linked elements. Theimportance of concision cannot be overstated nonetheless. Facebook is entitled to provide additionalinformation to its user above and beyond that required by Article 13 and can provide whateveradditional information it wishes. However, it must first comply with more specific obligations under theGDPR, and then secondly ensure that the additional information does not have the effect of creatinginformation fatigue or otherwise diluting the effective delivery of the statutorily required information.That is simply what the GDPR requires.

    1. ROMANS 13 The Most Disastrously Misinterpreted Scripturein the History of the Human Race

      Interesting read. I'm amazed I hadn't found it sooner considering how common this position is among archist Christians.

    1. Prof. Meiri: "Our study tracked changes at a much higher resolution over a considerably longer period of time compared to previous research. The results were illuminating: we found a continual, and very significant, decline in the size of animals hunted by humans over 1.5 million years. For example, a third of the bones left behind by Homo erectus at sites dated to about a million years ago, belonged to elephants that weighed up to 13 tons (more than twice the weight of the modern African elephant) and provided humans with 90% of their food. The mean weight of all animals hunted by humans at that time was 3 tons, and elephant bones were found at nearly all sites up to 500,000 years ago. "Starting about 400,000 years ago, the humans who lived in our region -- early ancestors of the Neandertals and Homo sapiens, appear to have hunted mainly deer, along with some larger animals weighing almost a ton, such as wild cattle and horses. Finally, in sites inhabited by modern humans, from about 50,000 to 10,000 years ago, approximately 70% of the bones belong to gazelles -- an animal that weighs no more than 20-30kg. Other remains found at these later sites came mostly from fallow deer (about 20%), as well as smaller animals such as hares and turtles."

      Progression of body mass over the last 1.5 million years in the Southern Levant: 1) Up to 500,000 years ago 1/3 of bones left behind at Homo Erectus sites belonged to 13 ton elephants that provided 90% of the food. Mean weight of all hunted animals at the time was 3 tons 2) Up to 400,000 years ago, early Neandertals and Homo Sapiens only hunted mainly deer and animals like wild cattle and horse that weighed no more than 1 ton. 3) From 50,000 to 10,000 years ago, 70^ of bones at modern human sites belonged to gazelles weighing between 20 and 30 kg, as well as fallow deer and hares and turtles.

    1. The variation of bandgap energy (Eg) and Urbach energy(EU) of ZnS thinfilms with deposition times is shown inFigure 13. TheEgvalues of ZnSfilms decrease with increas-ing deposition time which is due to the agglomeration ofthe ZnS-NPs. The minimum value ofEUobtained at 20 minindicates a very weak absorption tail due to minimizeddefects and impurities which improves the transparencyand optical conductivity of thefilm coated at that time.

      La variación de la energía del band gap y de Urbach de las películas delgadas de ZnS con tiempos de deposición es mostrado en la figura 13. La valores del energía band gap de las películas ZnS decrecían con el incremento del tiempo de deposición lo cual es debido a la aglomeración de las ZnS-NPS. El valor mínimo de la energía de Urbach obtenido a 20 min indica una muy débil cola de absorción debido los defectos minimizados e impurezas que mejoran la transparencia y la conductividad óptica en el revestimiento de la pelicula en ese momento.

    1. with the plunger of a Hamilton syringe. The tube was centrifuged at room temperature at 14,000 rpm for 30 min. The above process of gel-disruption and centrifugation was repeated twice subsequent to which the oil layer was aspirated and suitable aliquots from the supernatant were taken for estimation of Csat by Drabkin' s reagent (Goldberg eta!, 1977).
    2. he gelation concentrations of HbS constructs were determined by the dextran-Csat method of Bookchin et a! (Bookchin et a!, 1999). This method allows measurement of Csat under near-physiological conditions and at much lower concentration of HbS (about 5-fold or less) than that required in standard Csat assays, but essentially provides the same information. Briefly, a suitable aliquot of a concentrated solution of hemoglobin in potassium phosphate buffer (0.05 M, pH 7.50) was taken in a 1.5 ml micro-centrifuge tube. A concentrated dextran (70 kDa) solution prepared in the same buffer was added to it and mixed well. This mixture was overlaid with 0.5 ml of mineral oil, chilled on ice bath and deoxygenated with an anaerobically prepared dithionite solution through an airtight Hamilton syringe. The final concentrations of dextran and dithionite in the mixture were 120 mg/ml and 0.05 M respectively. The deoxygenated sample above was allowed to polymerize at 37°C for 30 min after which the gel under the oil layer was disrupted

    1. Parasite cultures were distributed in six well plates (2 ml per well) and pharmacological inhibitors were added at desired concentration. Plates were placed in small gas chambers, gassed and immediately returned to 37°C incubator. The lysates were prepared after ~30 min of the addition of inhibitors
    2. Inhibitor Treatment of gametocyte
    1. Intracellular Na + measurement was performed using the fluorescent Na + indicator Sodium Green TM tetracetate. THP-1 macrophages were resuspended in phenol-red free RPMI-1640 medium and incubated with Sodium Green™ at a final concentration of 1 JiM for 20 min at room temperature. The cells were washed once with fresh serum-free media to remove excess probe following which kinetic fluorescent measurements were commenced in a spectrofluorimeter (BMG Fluostar Optima) at an excitation of 480 nm and emission of 520 nm. In situ calibration to determine the dissociation constant (Kct) of the dye at 3 7°C was accomplished by using the indicator dye in solutions of precisely known free Na+ concentration in the presence of the pore forming antibiotic gramicidin (10 J,tM). Intracellular Na+ was calculated using the following formula: where, Kct of the dye is 5.7 mM at 37°C, F is the fluorescence of the experimental sample, Fmin is the fluorescence in the absence of Na+ and Fmax is the fluorescence under saturating concentrations ofNa+ in the presence of gramicidin (10 J.i.M)
    2. Assay for intracellular Na +measuremen
    1. Circular Dichroic spectra of various proteins were recorded at room temperature, using a JASCO J7i0 spectropolarimeter fitted with a thermostated cell holder. I 50 J..Lg protein was dissolved in 3 ml of I 0 mM sodium phosphate buffer (pH 7.0), and the samples were scanned in the far-UV range (200-250 nm). A cell with a 1 em optical path was used to acquire the spectra at a scan speed of 50 nrn/min. with a. sensitivity of 50 mdeg and a response time of I sec. The sample compartment was purged with nitrogen, and spectra were averaged over I 0 accumulations. The CD spectra were normalized to mean residue ellipticity curves using Jasco software. Yang's reference parameters were used to perform secondary structure analyses from CD measurements using Jasco Secondary Structure Estimation Programme (Yang et al., 1986).

    1. transferred to another plastic box containing 2 X sse, 1 % SDS and washed at room temperature by gentle rocking for 15 minutes. The buffer was then changed and the washing continued at 60 in a shaking water bath for 30 minutes. Depending on the homology between the probe and the immobil ised DNA, the washing conditions were varied. The stringency ranged from 1 X sse, 1 % SDS, at 65°e to 0.2 X sse, 1 % SDS, at 65°e. After the washing, the filters were immediately sealed into plastic bags and put for autoradiography. Special care was taken to not to allow the filters to dry during any stage which might otherwise cause permanent binding of the probe to the filter preventing the reprobing of the same filter with a different probe at a later time. For autoradiography, the plastic bag containing the washed filter was fixed on a 3 MM Whatman sheet and placed securely ins ide a X ray cassette with one or two intensifying screens, and a X -ray film was placed over the filter in a dark room. The cassette was kept at -7o0e for the desired length of exposure. The film was taken out in the dark room, developed for approximately 3 minutes, washed in water for one minute to wash off all the developer adhering to the film, and fixed for 5 minutes. Finally, the film was washed in cold water for 10 minutes and air dried
    2. The prehybridisation and hybridisation of the Southern filters was carried out as described by Maniatis et al., ( 1982 ), with some modifications. In all stages, the SDS concentration was maintained at 1 % to minimise the background likely to occur on the nylon membrane. Prehybridisation was done at 68°C, for 4 - 6 hours, with 0.1 ml of prehybridisation buffer for each square centimeter of the membrane. The probe was denatured by immersing the eppendorf tube in a boiling water bath for 10 minutes and added directly to the bag containing prehybridisation mix. Hybridisation was done in aqueous system, at 68°e, without the use of formam ide, for 18 - 2 4 hours, in a plastic bag kept submerged in a water bath, without any shaking. At the end of hybridisation, the filter was taken out of the bag and quickly immersed in a plastic box containing 5 X sse, 1 % SDS at room temperature. After 15 minutes, the filter was

    4. hours. The NC filters having bound DNA liberated from bacterial colonies, were set up for hybridisation with radioactive probes as described by Maniatis et al., ( 1982 ). The filters were washed thoroughly with a solution containing 50 mM Tris.Cl, pH 8.0, 1 M NaCl, 1 mM EDTA, 1 % SDS, at 42°C, for 1 hour, to wash off any residual bacterial debris and agar etc. Prehybridisation and hybridisation was performed in aqueous solution without formamide in 5 X SSPE. The filters were washed up to a stringency of 0.2 X sse at 65°e.
    5. Colonies bound to nitrocellulose filter ( NC ) were lysed to liberate the DNA which was hybridised as described by Maniatis et al., 1982 ) . To obtain sharper autoradiography signals, the nitrocellulose filter bearing colonies was first overlaid on a 3 MM Whatman paper impregnated with 10 % SDS till the NC wetted evenly. The NC was peeled off and overlaid on another 3 MM paper impregnated with the denaturing solution. In this manner, the NC was successively treated with denaturing and neutralising solutions. Finally, the NC filter was air dried, sandwiched between two sheets of 3 MM paper and baked at 80°C for two

The antibody response generated was represented as the geometric mean of the absorbance of individual mice sera in a group of immunized animals. b1 addition, the antibody titer against r-dZP3 was also determined by ELISA. The assay was carried out as described above except that 100 ~l of doubling dilutions of the serum samples (dilutions made in PBST supplemented with 0.1% BSA) were added per well in duplicate. For each serum sample tested, a reciprocal of dilution giving an absorbance of 1.0 was calculated by regression analysis and represented as antibody units (AU).
    4. Microtitration plates were coated with optimized concentration of r-bmZP1 (250 ng/well), r-dZP3 (400 ng/well) or r-rG (500 ng/well) in 50 mM PBS, pH 7.4, at 37°C for 1 h and then at 4°C, 0/N. The plates were washed once with PBS and incubated with 1% BSA, (200 Jll/ well) in PBS for 2 h at 37°C for blocking the non-specific sites. All subsequent incubations were carried out for 1 h at 37°C and each incubation was followed by three washings with PBS containing 0.05% Tween-20 (PBST). Post-blocking, the plates were incubated with 1 :50 dilution of either the preimmune or the immune serum samples obtained from mice immunized with the respective plasmid DNA. Antibodies bound tor-bmZP 1, r-dZP3 and r-rG were revealed with 1:2000 dilution of goat anti-mouse IgG (whole molecule) HRPO (Dako). Estimation of the enzymatic activity was carried out with 0.05% OPD in 50 mM citrate phosphate buffer, pH 5.0, containing 0.06% H202 as the substrate.

These cartridges were used to deliver DNA into epidermis of male/female mice. a) Preparation of DNA-gold microcarrier suspension Twenty five mg of gold microcarriers were weighed in a 1.5 ml eppendorf tube to which 100 J..Ll of 0.05 M spermidine was added and vortexed for 10 sec. To the above mixture 100 J..Ll of DNA (0.5 mg/ml) was added and vortexed for another 10 sec. While vortexing, 100 J..Ll of 1 M CaCh was added dropwise to the mixture and left at RT for 10 min to allow precipitation of DNA onto gold microcarriers. The DNA-gold pellet was collected by centrifuging at 12,000 X g for 1 min at RT. The pellet was washed thrice with 100% ethanol (freshly opened bottle), resuspended in 3 ml of 0.1mg/ml polyvinylpyrollidone (PVP) in ethanol and stored at -20°C till further use. b) Loading the DNA/microcarrier suspension into gold-coat tubing using the tubing prep station A 25 inch length of tubing was cut and fixed on tubing prep station, air dried by passing nitrogen gas through it for 15 min. The DNA/microcarrier suspension was vortexed and injected into the tubing using a 5 ml syringe and the microcarriers allowed to settle in the tubing for 3 min. Ethanol from the tubing was removed by slowly sucking into the syringe. The tubing was rotated, while passing the nitrogen gas, using the tubing prep station, for 20-30 sec to allow the microcarriers to evenly coat the inside of the tubing. c) Preparation of cartridges using the tubing cutter The tubing was cut into 0.5 inch long pieces (cartridges) by using the tubing cutter and cartridges stored at 4°C in vials containing desiccant pellets till further use.

    16. a) Purification oLin elusion bodies For the purification of inclusion bodies, the bacterial cell pellet from 1 liter culture was resuspended in 10 ml of Tris-HCl buffer (50 mM; pH 8.5) containing 5 mM EDTA and sonicated using Branson sonifier-450 for 8 cycles of 90 sec each (30 watt output; Branson Ultrasonic Corp., Danbury, CT, USA) on ice. The inclusion bodies were collected by centrifugation of the sonicate at 8000 X g for 30 min at 4°C. The pellet was washed twice with 15 ml of 50 mM Tris-HCl buffer with 5 mM EDTA containing 2% sodium deoxycholate in order to remove loosely bound E. coli proteins from the inclusion bodies. Subsequently, the inclusion body pellet was washed with 50 mM Tris-HCI buffer (pH 8.5), followed by a washing with the double distilled water. All the buffers used for the purification contained 20 mM of phenylmethyl sulphonyl fluoride (PMSF). b) Solubilization and renaturation The purified inclusion bodies were solubilized in 100 mM Tris-HCl (pH 12.0) containing 2M urea at RT for 30 min, and centrifuged at 8000 X g for 30 min at 4°C. The pH ofthe supernatant was brought down immediately to 8.5 with 1 N HCl and then extensively dialyzed against renaturation buffer (50 mM Tris-HCl buffer; pH 8.5, 1 mM EDT A, 0.1 mM reduced glutathione, 0.01 mM oxidized glutathione and 10% sucrose). The protein was finally dialyzed against 20 mM Tris-HCl, pH 8.5 and its concentration estimated using BCA.
    17. Purification in refolded form
    18. The proteins were purified by nickel affinity chromatography. The cell pellet ( ~ 1 g) of each clone was solubilized in 5 ml ofbuffer A (6 M guanidine hydrochloride, 0.1 M NaH2P04, 0.01 M Tris, pH 8.0). The suspension was centrifuged at 8000 X g for 15 min at 4°C and the supernatant containing the recombinant protein was mixed with Ni-NT A resin (Nickel-Nitrilotriacetic acid equilibrated with buffer A) and kept for gentle end-to-end shaking for 1 hat RT. The resin was loaded on a column and washed with 10 bed-volumes of buffer A. The column was subsequently washed with 5 bed-volumes each of buffers B, and C, which contained 8 M urea, 0.1 M NaH2P04 and 0.01 M Tris and had successively reducing pH values of 8.0 and 6.3 respectively. The protein was eluted with buffers D and E (composition same as buffer B) in which the pH was further reduced to 5.9 and 4.5 respectively. Five fractions of 4 ml each were collected during elution with buffer D and buffer E respectively. The eluted proteins were analysed by 0.1% SDS-1 0% PAGE (gels stained with Coomassie blue) and Western blot. The fractions showing the purified recombinant protein were pooled and concentrated in an Amicon concentrator using a YM30 membrane and dialyzed against 100 mM phosphate buffer, pH 7.4, containing 4 M urea. The concentration of each purified protein was estimated by bicinchoninic acid (BCA).

    1. For clonogenic assays, 1x103 (A549) or 2x103 (E-10) cells were seeded per well of a six well tissue culture plate and grown for 15 days. For identification of signaling pathways various inhibitors were used viz, PI3K inhibitor LY294002 (10μM), MEK inhibitor PD98059 (10μM) or p38 inhibitor SB203580 (10μM). Cells were grown in the presence of inhibitor for seven days following which fresh medium was added. For staining, cells were washed twice with PBS and fixed in 10% formalin for 10 minutes, washed extensively with water and stained with 0.25% crystal violet prepared in 25% methanol for 4hrs at 4°C. Plates were then washed with milli Q water and dried before scanning

    1. the membrane and sandwiched between 1 piece of buffer-soaked Whatman paper from Biorad on each side. The sandwich was placed between graphite electrodes with the membrane towards the anode. The transfer was done for 12-16 hr using a voltage of 40 V in the cold room. Protein transfer was viwed using Ponceau S staining. Blot was dipped in the Ponceau S stain under shaking and washed using PBST. After transfer, the membrane was blocked with 5% non-fat milk in PBST (1X PBS with 0.1% Tween-20) for 2 hr at room temperature. The membrane was then washed thrice with PBST under shaking and incubated with the primary antibody (1:1000 dilution in PBST) for 12-16 hr. The membrane was again washed thrice under shaking with PBST and incubated with 1:20000 dilution alkaline phosphatase conjugated anti-goat IgG secondary antibody (in PBST) for 2 hr. The membrane was once again washed thrice as described above and the signal developed using ECL kit from Amersham on X-ray films in a dark room. The reactive protein bands appeared as black bands upon gentle shaking at room temperature in 1X developer solution. The reaction was stopped by dipping and shaking the film in 1X Fixer solution followed by washing in water
    2. The protein samples separated on SDS-PAGE were transferred to PVDF (polyvinyledene difluoride) membrane (Amersham, Buckinghamshire, UK) electrophoretically by a semi-dry method using BioRad apparatus.

    3. Western blotting with anti-Rho/anti-NusG antibody
    4. Obtaining transpositions near a gene of interest was achieved in a two-step procedure. The population (pool) of cells carrying random transpositions (described in the previous Section) at different places on the chromosome was used to prepare a P1 phage lysate. This lysate was then used to infect a suitable recipient strain and transductants were sought in a simultaneous (double) selection for two markers, namely the antibiotic marker on the mini-transposon and selection for the phenotype of the gene or mutation which was intended to be linked with the antibiotic marker. The transductants so isolated were purified and further P1 phage preparations were made on these individual clones. By retransducing with these lysates into the same recipient cells and observing the segregation of phenotypes after selection for the transposon marker, the cotransduction values were obtained between the transposon insertion and the gene (or mutation) of interest
    5. Obtaining transposon insertions near gene of interest
    1. A bioluminescent ATP determination kit from Invitrogen (Carlsbad, CA) was used to quantitate ATP levels. The assay is based on luciferase' s requirement for ATP for producing light (emission maxima at 560nm). The assay was carried out as described previously (Mukherjee et al., 2002). Briefly, a standard reaction mix was prepared-1X reaction buffer, 0.1p.M DTT, O.Sp.M Luciferin and 12.5 p.g/ mL Luciferase. 100 p.L was aliquoted into each well of a 96 well white plate and a base line reading measured using Fluostar Omega using the luminometer adaptor. Then either 106 parasites or different concentrations of A TP (prepared from the stock solution provided in the kit) were added to these wells as test and standard curve samples respectively. Again luminescence was measured and the baseline subtracted from the readings. The different dilutions of ATP were used to plot the standard curve which was then used to calculate the ATP levels in cells expressed as nmol/106 cells.
    2. Materials and Methods the MTT Lysis buffer (20% SDS , 50% Dimethyl formamide) and the O.D.s7onm was measured. The standard curve was plotted and the equation derived, used to calculate the number of metabolically viable cells in experimental groups. Percentage of viable cells was calculated by comparing the number of viable cells in treated wells with that of untreated wells. 3.2.C.13 ATP determination
    3. run on an agarose gel and band size determined by comparison against DNA ladder with bands of known sizes. Clones that were positive for the presence of gene/ plasmid were further checked by restriction digestion. For restriction digestion, plasmid was first isolated by Miniprep as described below. The digestion reactions were set according to manufacturer's protocol appropriate for the enzymes used. The products were run on an agarose gel and band size determined by comparison against DNA ladder with bands of known sizes. Clones with the desired pattern of digestion were propagated further and used
    4. Bacterial colonies obtained by transformation were checked for the presence of plasmid or gene inserted into the plasmid by colony PCR and restriction digestion. For PCR, a master mix for all the PCR reactions to be performed was made, aliquoted into PCR vials and stored on ice. Individual colonies were picked up, numbered and streaked onto an LB agar plate followed by deposition of a few cells into the PCR mix. PCR was carried out as described above for the respective primer pairs with the exception that the initial denaturation was carried out for 7 min at 94 °C. The products were

    1. Quantitative measurement of periplasmic acid phosphatase activity in phosphate-starved C. glabratacells was performedas mentioned previously (Orkwis et al., 2010). A total of 0.5 OD600YNB-grown and phosphate-starved cells were collected, washed thrice with cold water and oncewith cold 0.1 M sodium acetatebuffer (pH 4.2). Washed cells were resuspendedin 500 μl sodium acetate (0.1 M)and incubated at 30 ̊C with constant stirring. After 10 min incubation, 500 μl freshly-prepared solution of 20 mM p-nitrophenyl phosphate in 0.1 M sodium acetate(pH 4.2) was added to the cell suspension. Enzymatic activity was stopped after incubation at 25 ̊C for 20 min by addition of 250 μl sodium carbonate (1 M)tothe reaction mix. Resultant colour change was measured by monitoring absorbance at 400 nm. Acid phosphatase activity was expressed as a ratio of OD400to OD600 to normalize against cell density
