the effect of hydrogen ion concentration on the production of carbon dioxide by bacillus butyricus and bacillus subtilis.1. the maximum rate of co(2) production of bacillus butyricus was found to be at a ph value of 7; of bacillus subtilis at ph 6.8. if the ph value be raised or lowered there is a progressive decrease in the rate of production of co(2). 2. spontaneous recovery follows the addition of alkali to either organism, while addition of acid is followed by recovery only upon addition of an equivalent amount of alkali, and is not complete except when the amount of acid is very small.192119871925
conductivity as a measure of vitality and death.the conductance of laminaria, saccharomyces, bacillus coli and bacillus butyricus, chlorella, and of red blood cells has been studied by the writer's method, and laminaria by that of osterhout. for the material studied it has been found that: 1. the conductance of living tissue is closely proportionate to, and determined by that of the surrounding fluid with which it is apparently in equilibrium. changes in the conductance of the fluid are quickly followed by compensatory changes in that of the ...192319872003
