	''Ruminococcus flavefaciens'' FD-1 is a strictly anaerobic bacterium isolated from the bovine rumen by Marvin P. Bryant in 1953. This bacterium is known to deconstruct lignocellulose efficiently using cellulosomes, which are highly modular enzymatic complexes [1]. The efficient degradation of lignocellulose by strain FD-1 results in the production of volatile fatty acids that are absorbed across the rumen epithelium, directly supporting the metabolic and energetic requirements of the ruminant host. Furthermore, the hydrogen evolved during its fermentation process is utilized by syntrophic methanogens, linking the robust fibrolytic activity of FD-1 to ruminal methanogenesis. The extensive genetic and structural mapping of ''R. flavefaciens'' FD-1 has established it as a critical benchmark strain for understanding the molecular assembly of bacterial cellulosomes and exploring biotechnological applications in lignocellulose bioconversion.
