A new genus and species of a nonmotile gram-negative rod, Syntrophobacter wolinii, is the first bacterium described which degrades propionate only in coculture with an H/sub 2/-using organism and in the absence of light or exogenous electron acceptors such as O/sub 2/, sulfate, or nitrate. It was isolated from methanogenic enrichments from an anaerobic municipal sewage digestor, using anaerobic roll tubes containing a medium with propionate as the energy source in association with an H/sub 2/-using, sulfate-reducing Desulfovibrio sp. which cannot utilize fatty acids other than formate. S. wolinii produced acetate and, presumably, CO/sub 2/ and H/sub 2/ (or formate) from propionate. In media without sulfate and with Methanospirillum hungatei, a methanogen that uses only H/sub 2/-CO/sub 2/ or formate as an energy source, acetate, methane, and, presumably, CO/sub 2/ were produced from propionate and only small amounts of Desulfovibrio sp. were present. Isolation in coculture with the methanogen was not successful. S. wolinii does not use other saturated fatty acids as energy sources. 2 figures, 3 tables.
