DETERMINATION OF HEAT SHOCK PROTEINS IN SOME BACILLUS SPECIES

In this study, the effects of four different temperatures on sporulation and development 6 Bacillus species, 2 native 4 reference were investigated. The SDS PAGE analysis emerged that two proteins, 40 39 kilodalton (kDa), produced by sphaericus ATCC 2362 after 24 48, respectively hours at 48°C, local isolate 48 42°C 31 48°C. Additionally firmus (ATCC 14573) a kDa protein 52°C thuringiensis var. israelensis 42 42°C. At 52°C, 12, incubation, vegetative heat resistant spore counts determined to reduce 104-106 fold according bacterial counts. As result, data revealed vitality fell significant degree. Additionally, results showed high temperature resistance was provided shock proteins B. (14573), 40-39 2362), isolates israelensis.
