A new H2/CO2-using acetogenic bacterium from the rumen: description of Ruminococcus schinkii sp. nov.
Two strains of H2/CO2-using acetogenic bacteria were isolated from the rumen of suckling lambs. Both strains displayed a coccobacillar morphology and possessed a Gram-positive type cell wall. Numerous organic substrates, including some O-methylated aromatic compounds, were used heterotrophically. 16S rRNA gene sequencing demonstrated that the two acetogenic isolates were phylogenetically identical and represent a new subline within Clostridium cluster XIVa. Based on phenotypic and phylogenetic considerations a new species, Ruminococcus schinkii sp. nov., is proposed.
