Abstract

An anaerobic obligately syntrophic fatty acid degrading acetogenic bacterium (Strain OM) was isolated on calcium laurate medium from an oleate enrichment. This organism is a short slightly curved Gram-negative rod which can only use protons as electron acceptor. It ferments all linear saturated fatty acids with 4 to 18 carbon atoms in coculture with a hydrogen-utilizing partner. Some mono- and di-unsaturated long chain fatty acids (oleate, elaidate and linolenate) are also oxidized. Calcium is required for batch cultivation of the syntrophic association on fatty acids with a chain length longer than 8 carbon atoms. In spite of some important morphological and nutritional analogies with Syntrophomonas wolfei, the strain OM must be considered as a different species mainly because of its broader substrate range. The description of strain OM as type strain of a new species, Syntrophomonas sapovorans sp. nov., is proposed.
