    Abstract / Zusammenfassung

    A strain of an unidentified strictly anoxic, gram-postive, non-motile Ruminococcus-like bacterium was isolated from a human faecal sample. The organism used carbohydrates as fermentable substrates, produced acetate, succinate, and hydrogen as the major products of glucose metabolism, and possessed a G + C content of 43.3 mol%. The morphological and biochemical characteristics of the organism were consistent with its assignment to the genus Ruminococcus but it did not correspond to any recognized species of this genus. Comparative 16S rRNA gene sequencing showed the unidentified bacterium represents a previously unrecognised sub-line within the Clostridium coccoides rRNA group of organisms. The nearest relative of the unknown bacterium corresponded to Ruminococcus obeum but a 16S rRNA sequence divergence value of >3% demonstrated it represents a different species. Based on the presented findings a new species, Ruminococcus luti, is described. The type strain of Ruminococcus luti is BInIX(T) (DSM 14534T, CCUG 45635T).
