Production of keto acids by washed cells of the barotolerant strains was studied under atmospheric pressure on a glucose-mineral medium in balloons made of the copolymer of ethylene with propylene. Production of keto acids in these conditions requires elevated concentrations of glucose and minimum concentrations of ammonium nitrogen. Active aeration inhibits the accumulation of keto acids by the barotolerant bacteria. The majority of the barotolerant bacteria did not form free extracellular keto acids, other bacteria liberated comparatively small amounts of these acids. The ability to accumulate keto acids was different in particular strains.
