Inhibition of acetate and propionate formation upon aeration of resting cells of the anaerobic Propionibacterium shermanii: evidence of the Pasteur reaction.


When resting cell suspensions of the anaerobic P. shermanii were brought to an oxygen concentration of 0.64 mumoles/ml, acid formation was completely inhibited. The cells started to respire on the propionic acid previously accumulated furing anaerobiosis. Glucose consumption was concomitantly decreased to about 60 percent of the rate during anaerobiosis.
