ABSTRACT
The current chapter describes the relationships between the temperature of cultivation of Bacteria from the Bacillus genus, extracted from Arctic permafrost, and the activity of oxidation stress ferments at the example of catalase. Bacteria were cultivated under 5, 22, and 45°C. The catalase activity of cultures under study varied from 0.73 to 12.35 units×mg−1 of protein and from 0.62 to 14.16 mg−1 under temperatures of 45°C and 22°C, respectively. The catalase activity of cultures, cultivated under 5°C, was several times higher than under 45 and 22°C, varying from 10.46 to 26.79 units×mg−1 of protein. The increase of catalase activity under low positive temperatures indicates high antioxidant protection under hypothermia stress.
