Butyrivibrio fibrisolvens + Selenomonas ruminantium + Ruminococcus albus Lignocellulolytic Rumen Consortium

Community ID CommunityMech:000275

Ecological State ENGINEERED

Environment bovine rumen microbial strains grown in in vitro cocultures
ENVO:01001405

A synthetic lignocellulolytic bacterial consortium designed from six bovine rumen microbial strains to enhance lignocellulose degradation for biofuel and enzyme production. Genome-scale community metabolic models were used with flux-based parameters (pairwise metabolic assistance, PMA; growth support index, PGSI) to predict compatible, mutualistic pairs, which were validated in experimentally grown cocultures. The strongest pairwise enzymatic synergism was observed for Butyrivibrio fibrisolvens with Selenomonas ruminantium (a 41% increase in endoglucanase activity), and a three-membered community of B. fibrisolvens, S. ruminantium, and Ruminococcus albus showed synergistic activity across all lignocellulosic substrates, indicating strong metabolic interplay among compatible species.
