ABSTRACTMembers of the genusFibrobacterare cellulose-degrading bacteria and common constituents of the gastrointestinal microbiota of herbivores. Although considerable phylogenetic diversity is observed among members of this group, few functional differences explaining the distinct ecological distributions of specific phylotypes have been described. In this study, we sequenced and performed a comparative analysis of whole genomes from 38 novelFibrobacterstrains against the type strains for the two formally describedFibrobacterspeciesF. succinogenesstrain S85 andF. intestinalisstrain NR9. Significant differences in the number of genes encoding carbohydrate-active enzyme families involved in plant cell wall polysaccharide degradation were observed amongFibrobacterphylotypes.F. succinogenesgenomes were consistently enriched in genes encoding carbohydrate-active enzymes compared to those ofF. intestinalisstrains. Moreover, genomes ofF. succinogenesphylotypes that are dominant in the rumen had significantly more genes annotated to major families involved in hemicellulose degradation (e.g., CE6, GH10, and GH43) than did the genomes ofF. succinogenesphylotypes typically observed in the lower gut of large hindgut-fermenting herbivores such as horses. Genes encoding a putative urease were also identified in 12 of theFibrobactergenomes, which were primarily isolated from hindgut-fermenting hosts. Screening for growth on urea as the sole source of nitrogen provided strong evidence that the urease was active in these strains. These results represent the strongest evidence reported to date for specific functional differences contributing to the ecology ofFibrobacterspp. in the herbivore gut.IMPORTANCEThe herbivore gut microbiome is incredibly diverse, and a functional understanding of this diversity is needed to more reliably manipulate this community for specific gain, such as increased production in ruminant livestock. Microbial degraders of plant cell wall polysaccharides in the herbivore gut, particularlyFibrobacterspp., are of fundamental importance to their hosts for digestion of a diet consisting primarily of recalcitrant plant fibers. Considerable phylogenetic diversity exists among members of the genusFibrobacter, but much of this diversity remains cryptic. Here, we used comparative genomics, applied to a diverse collection of recently isolatedFibrobacterstrains, to identify a robust association between carbohydrate-active enzyme gene content and theFibrobacterphylogeny. Our results provide the strongest evidence reported to date for functional differences amongFibrobacterphylotypes associated with either the rumen or the hindgut and emphasize the general significance of carbohydrate-active enzymes in the evolution of fiber-degrading bacteria.
