Thermophilic bacteria from hot springs of Kamchatka

: Spore-forming bacteria with the optimum growth temperature from 40 to 65 degrees C were isolated from hot springs of Kamchatka with the temperature 50-93 degrees C and pH 6.3-7.3: Bacillus stearothermophilus, B. brevis, B. subtilis, B. cereus, B. megaterium, and B. licheniformis. The bacterial have a high biochemical activity and play therefore an important role in decomposition of organic substances.
