Abstract

Bacteria that produce cellulase were isolated from rice straw and sugarcane straw and screened using the Congo Red technique. 16S rDNA analysis was used to identify the highly cellulolytic isolates. CH1-Rice has homology with Brevibacillus sp., while CH5-Sugarcane has homology with Klebsiella variicol, according to phylogenetic tree analysis of their 16S rDNA gene sequencing information’s. Bacterial optimum growth conditions were adjusted by manipulating nutritional and environmental parameters as temperature, pH, cellulose concentration, incubation time, salinity, and different carbon sources. The activity was estimated by measuring the turbidity of bacteria with a spectrophotometer. In conclusion, Two different bacterial strains were discovered and isolated, and the optimal growth conditions for each were identified. These strains might be employed to transform plant waste into more beneficial substances.
