[Adaptive mechanisms in the ecology of the pseudotuberculosis microbe]

The paper presents the radiorespirometric and enzymatic findings of the insensitivity of catabolism of glucose and acetate in Y. pseudotuberculosis cells. The reduction in a Y. pseudotuberculosis cultivation temperature (4 degrees C) has been found to be followed by higher activities of NADP(+)-dependent dehydrogenases and increased functioning of the glyoxylate cycle. The temperature-compensated increase in the functioning intensity of alternative metabolic pathways appears to be part of adaptative metabolic manifestations in the Y. pseudotuberculosis cells during autonomic habitance and accumulation in the environmental objects.
