Abstract
Abstract Identical naphthoquinones have been isolated from the strict anaerobic sulfate reducing bacteria D . vulgaris and D . gigas . The vitamin was identified from both organisms as a menaquinone-6 (MK-6) by its characteristic chromatographic mobility and by mass spectral analysis. As the organisms possess cytochrome c3 and carry out phosphorylation coupled to the oxidation of hydrogen with sulfite as electron acceptor, it is possible that MK-6 is involved as an oxidation-reduction component in the electron transport pathway in these anaerobes.
