Abstract
A spore-forming bacterium strain 4J5(T) was isolated from rice field mud. When co-cultured with Methanobacterium formicicum DSM 1535(T), strain 4J5(T) could syntrophically degrade saturated fatty acids with 4-8 carbon atoms, including 2-methylbutyrate. Phylogenetic analysis based on 16S rRNA gene similarity showed that strain 4J5(T) was most closely related to Syntrophomonas wolfei subsp. wolfei DSM 2245(T) (98.9% sequence similarity); however, it differed from the latter in the substrates utilized and its genetic characteristics. Therefore, a new subspecies Syntrophomonas wolfei subsp. methylbutyratica is proposed. The type strain is 4J5(T) (=CGMCC 1.5051(T)=JCM 14075(T)). Furthermore, based on 16S rRNA sequence divergence and substrate utilization, we propose the assignment of Syntrophomonas wolfei subsp. saponavida DSM 4212(T) to Syntrophomonas saponavida sp. nov. comb. nov.Entities:
