Studies on Thermal Resistance Bacteria. (Part. 1)

내열성 세균에 관한 연구 1

The purpose of this paper is to study on the morphological and physiological nature generally observed for the identifications, and the four strains of thermal resistanting aerobic bacteria isolated from swelled cans and the different soils collected from the wide area in Korea. The results obtained in the light of the Bergey's Manual for the identification of the bacteria, have been shown that the four strains of bacteria are pertained to Bacillus subtilis. The optimum temperature, pH and the thermal resistance (2.5 min. at $121^{\circ}C$) of the bacteria have been measured.
