Abstract
Two mixed cultures able to ferment acrylate to equimolar acetate and propionate were enriched from anaerobic sediments. From one of these mixed cultures a pure culture of a Gram-positive, obligately anaerobic bacterium was isolated. This strain, designated 19acry3 (= DSM 6251) was identified as belonging to the species Clostridium propionicum. Only a narrow range of organic compounds supported growth, including acrylate and lactate. Acrylate and lactate were fermented to acetate and propionate in a 1:2 molar ratio. When co-cultured with the non-acrylate-fermenting “Campylobacter” sp. strain 19gly1 (DSM 6222), the fermentation balance shifted to almost equimolar acetate and propionate. Strain 19acry3 was compared with Clostridium propionicum type strain X2 (DSM 1682). The two strains displayed similar phenotypic properties. The mol% G+C of DNA isolated from both strains was 36–37 (by thermal denaturation). Both strains displayed a characteristic fluorescence when observed by fluorescence microscopy. Cell-free extracts of both strains were examined by spectrophotofluorimetry. In both strains, two excitation peaks were observed at 378 and 470 nm. Excitation at either of these wavelengths resulted in an emission maximum at 511 nm.
