Clostridium hathewayi sp. nov., from human faeces.
A strictly anoxic, Gram-positive, sporeforming, rod-shaped bacterium was isolated from a chemostat inoculated with human faeces. The bacterium used carbohydrate as fermentable substrates, producing acetate, ethanol, carbon dioxide and hydrogen as the major products of glucose metabolism, and possessed a G + C content of 50.7 to 50.9 mol%. Comparative 16S rRNA gene sequencing showed that the unidentified bacterium represents a previously unrecognised sub-line within the Clostridium coccoides rRNA group of organisms. The nearest relatives of the unknown bacterium corresponded to Clostridium algidixylanolyticum, C. aerotolerans, C. celerecrescens, C. indolis, C. sphenoides, C. methoxybenzovorans and C. xylanolyticum but 16S rRNA sequence divergence values of >4% demonstrated that it represents a novel species. Based on the presented findings a new species, Clostridium hathewayi, is described. The type strain of Clostridium hathewayi is DSM = 13479T (= CCUG 43506 T).
