Abstract:
An anaerobic bacterial strain, designated strain M3/9 T , was isolated from a laboratory-scale biogas fermenter fed with maize silage supplemented with 5 % wheat straw. Cells were straight, non-motile rods, which stained Gram-negative. Optimal growth occurred between 30 and 40°C, at pH 7.5–8.5, and up to 3.9 % (w/v) NaCl was tolerated. When grown on peptone from casein and soymeal, strain M3/9 T produced mainly acetic acid, ethanol, and isobutyric acid. The major cellular fatty acids of the novel strain were C 16 : 0 and C 16 : 0 DMA. The genome of strain M3/9 T is 3757 330 bp in size with a G+C content of 38.45 mol%. Phylogenetic analysis allocated strain M3/9 T within the family Lachnospiraceae with Clostridium colinum DSM 6011 T and Anaerotignum lactatifermentans DSM 14214 T being the most closely related species sharing 57.86 and 56.99% average amino acid identity and 16S rRNA gene sequence similarities of 91.58 and 91.26 %, respectively. Based on physiological, chemotaxonomic and genetic data, we propose the description of a novel species and genus Anaeropeptidivorans aminofermentans gen. nov., sp. nov., represented by the type strain M3/9 T (=DSM 100058 T =LMG 29527 T ). In addition, an emended description of Clostridium colinum is provided.
