Ph value in cells
WebFeb 21, 2024 · I am conducting an experiment on how different pH levels effect the growth of E.coli. After researching, it is predicted that the most acidic pH level (pH 2) will be most effective at killing (or at least slowing down the growth) of bacteria. But my question is what does pH actually do to the bacteria cell and the biology behind it. WebNigericin was diluted to a final concentration of 5 μM from the 10-mM stock solution in absolute ethanol. PIPES buffers were used when the desired pH values were below 6.7. Cells were incubated with the nigericin/high K + buffers at different pH values for 10 min before the collection of pH calibration points. Prolonged incubation with the ...
