FIELD: medicinal and veterinary microbiology. SUBSTANCE: strain Bacillus stearothermophilus KK-VKM B-2130D is isolated from agar nutrient medium subjected for sterilization with steam vapor. Strain spores show high thermic stability, D value (ten-fold decrease of viable spores amount) is 3.4 and 2.0 min at 121 C and 132 C, respectively. Spores of the strain Bacillus stearothermophilus survive at 121 C in 5, 15, 30 min, perish in 45 and 60 min (in 70% and 100% samples). EFFECT: strain of bacterium indicated above. 1 dwg, 1 tbl
