[Effect of elevated hydrostatic pressure on the activity of catabolic enzymes in barotolerant bacteria].
The effect of elevated hydrostatic pressure on catabolic enzymes was studied with four strains of barotolerant bacteria isolated from ooze at high depth of the Pacific Ocean. Pseudomonas aeruginosa 0798 and Ps. sociovivum 0913, tolerant to a pressure of 500 atm, have more active catabolic enzymes than Ps. nonliquefaciens 0613 and Ps. acuta 039, which do not grow at a pressure of 500 atm. Changes in the activity of the enzymes caused by elevated hydrostatic pressure are similar to changes caused by the process of the culture aging.
