Ruminiclostridium thermocellum strain ATCC 27405 is valuable with reference to the next generation biofuel production being a degrader of crystalline cellulose. The completion of its genome sequence has revealed that this organism carries 3,376 genes with more than hundred genes encoding for enzymes involved in cellulysis. Novel protein domain discovery in the cellulose degrading enzyme complex of this strain has been attempted to understand this organism at molecular level. Streamlined automated methods were employed to generate possibly unreported or new domains. A set of 12 novel Pfam-B domains was developed after detailed analysis. This finding will enhance our understanding of this bacterium and its molecular processes involved in the degradation of cellulose. This approach of in silico analysis prior to experimentation facilitates in lab study. Previously uncorrelated data has been utilized for rapid generation of new biological information in this study.
