Cellulolytic bacteria were previously isolated from the termite guts and efforts were taken to optimize parameters for cellulase production. Activities of diversity of enzymes which include, CMCase, avicelase and filterpaperase (FPase) were studied from crude cellulase extracts. CMCase activity was found optimum at different temperatures (35°C, 40°C and 45°C) at pH 7 and after 48 hrs of incubation time. Avicelase and FPase activities were found optimum at 35°C, pH 7 and after 48 hours of incubation. Results clearly indicated that there is a great impact of temperature, pH and incubation period on cellulase production. Isolate C3 and Z were found highest CMCase and FPase producers respectively. 16s rRNA gene analysis confirmed that, isolates belong to different species of Pseudomonas, Klebsiella, Salmonella, Serratia and Enterobacter. Molecular characterization using REP, ERIC and BOX sequences showed high-moderate level of diversity among these isolates. Growth profiles of isolates showed that, they can grow best between temperatures 30°C-40°C at pH 7.
