Number of ORFs in the present metagenomic dataset that exhibited similarities to the genes in the sequenced genomes of the rumen fibrolytic bacterial species.

Notes: a total ORFs in the present metagenomic dataset that were found to be similar to the genes of each sequenced genome; b total ORFs in the metagenomic dataset that exhibited similarity to the CAZy genes of each sequenced genome; c-k ORFs in the metagenomic dataset that were found similar to the carbohydrate binding module (CBM), glycoside hydrolase (GH); glycosyl transferase (GT), carbohydrate esterase (CE), polysaccharide lyase (PL), signal peptide (SP), transmembrane domain (TM), and both SP and TM.*One GH3 in the metagenomic dataset exhibited 91% amino acid similarity with a GH3 in the genome of P. ruminicola 23.
