Effects of Temperature on Biological Activity of Permafrost Microorganisms

摘要

The number and viability of microorganism specimens Bacillus spp. isolated from permafrost soil remained unchanged after incubation at temperatures of -16-37A degrees C. Experiments on F1 CBA/Black-6 mice showed that incubation of bacteria at -5A degrees C for 72 h promotes a decrease in their toxicity and an increase in their immunostimulating effect.
