Abstract

Eight thermophilic bacterial strains were isolated from Tattapani Hot spring and screened for various hydrolytic enzymes including cellulases. The isolated bacterial strains were identified as Geobacillus thermodenitrificans IP_WH1(KP842609), Bacillus licheniformis IP_WH2(KP842610), B. aerius IP_WH3(KP842611), B. licheniformis IP_WH4(KP842612), B. licheniformis IP_60Y(KP842613), G. thermodenitrificans IP_60A1(KP842614), Geobacillus sp. IP_60A2(KP842615) and Geobacillus sp. IP_80TP(KP842616) after 16S ribotying. Out of the eight isolates Geobacillus sp. IP_80TP grew best at 80 °C whereas rest of the isolates showed optimal growth at 60 °C. G. thermodenitrificans IP_WH1 produced a thermotolerant cellulase with maximum activity at 60 °C.
