Abstract
Purpose
Cellulase, due to its massive applicability, has been used in various industrial processes such as biofuels (bioethanol, triphasic biomethanation), agricultural and plant waste management, chiral separation, and ligand binding studies. The finding of a novel cellulase-producing bacterium will benefit the industries, which rely on yeast to produce cellulase in fermentation technology, because bacteria can easily be manipulated and fermented cost-effectively.
Methods
Cellulase enzyme-secreting bacteria were isolated from different regions of the world’s largest mangrove forests, Sundarbans in Bangladesh. Biochemical, morphological, and 16S rRNA identification protocol was followed to precisely characterize the bacterial strains.
Result
We have determined that the strain T2-D2 (Bacillus sp.), E1-PT (Pseudomonas sp.), and D1-PT (Pseudomonas sp.) showed maximum endoglycolytic and strain C1-BT (Bacillus sp.), E1-BT (Bacillus sp.), and T-4 (E) showed relatively higher exoglycolytic activity during the test. So, it can be easily cultured at a normal temperature (97.7–99.5 °F). On the one hand, T2-D2 (Bacillus sp.) and E1-PT (Pseudomonas sp.) have shown the highest growth rate at pH 7 as it was neither acidic nor basic.
Conclusion
It was concluded that the strain T2-D2 (Bacillus sp.) and E1-PT (Pseudomonas sp.) would be our target cellulolytic strains wherein the experimental isolates belonged to the Enterobacteriaceae, Psuedomonacea, Bacillacea, and Morganellacea family.
