Abstract
Results using a constant concn. of CO2 with alkaline diethanolamine and with Keilin respiratory vessels show that O2 uptake by dilute suspensions of 38 common bacterial spp. utilizing glucose as substrate is greater in the presence of 0.8% CO2 than in micro-respirometer flasks in which the CO2 is absorbed by concentrated alkali. The degree of stimulation seems to be related inversely to the amt. of CO2 produced by the cells. When sufficient cells are present, this stimulation is not observed.
