Diversity of fumarate reducing bacteria in the bovine rumen revealed by culture dependent and independent approaches.
Diversity of fumarate reducing (dissimilating) bacteria in the bovine rumen was analyzed by both culture dependent and independent methodologies. A total of 39 strains were isolated by using three different media and belonged to three different phyla (Proteobacteria, Fusobacteria, and Firmicutes). A primer set that amplified the fumarate reductase gene (frdA) from Proteobacteria was developed and two frdA clone libraries were constructed. Identities of deduced amino acid sequences of cloned frdA amplicons against known sequences ranged from 58% to 85% suggesting the presence of unknown fumarate reducing bacteria. This is the first report on the diversity of fumarate reducing bacteria in the rumen.
