Abstract

Genome sequence of Paenibacillus polymyxa ND25 isolated from cow rumen is reported for being a potential candidate in hydrolysis of lignocellulosic plant biomass. Draft genome sequence generated 5.73 Mb data containing 4922 putative protein coding genes, of which 140 are annotated for glycoside hydrolases. P. polymyxa ND25 strain comprises diverse lignocellulolytic components, especially 12 cellulase along with 23 hemicellulases and 11 esterases, signifying its potential for lignocellulose hydrolysis. Subsequent enzyme assay exhibited the potential of strain to produce 0.49, 0.24 and 0.44 U/ml U/ml of endoglucanase, exoglucanase and β-glucosidase, respectively, utilizing sugarcane bagasse as the sole carbon source. This study signifies the efficient application of P. polymyxa ND25 for facilitating plant-biomass utilization.
