Abstract
The pH of optimum respiration, about 7.3 for Escherichia coli and 6.3 for B. cereus, is not altered when NaCl is added. If small concs. of the salt are added the rate of respiration is increased ; larger concs., diminish it. This is true whatever the pH. The effect of the salt in increasing respiration is greater the more the pH differs from that of opt. respiration, be it more acid or more alkaline. The conc., of NaCl needed to bring about the maximum stimulation of respiration is also least at the pH of opt. respiration. The inhibition of the respiration of either organism is expressed by an equation, which relates rate of respiration and conc., of NaCl whatever the pH. The values of Q in this equation are independent of pH, but differ for the 2 spp.This publication has 6 references indexed in Scilit:
