gen. nov., sp. nov., a novel bacterium of the family isolated from raw milk and dairy products and reclassification of as comb. nov. Free

Abstract

Eight facultatively anaerobic rod-shaped bacteria were isolated from raw milk and two other dairy products. Results of phylogenetic analyses based on 16S rRNA gene sequences showed that the isolates are placed in a distinct lineage within the family with and as the closest relatives (94.6 and 93.5 % similarity, respectively). The cell-wall peptidoglycan contained -diaminopimelic acid, alanine and glutamic acid and was of the A1γ type (-DAP-direct). The major cellular fatty acid was anteiso-C and the major polar lipids were diphosphatidylglycerol, phosphatidyglycerol and three unidentified glycolipids. The quinone system contained predominantly menaquinone MK-9(H). The G+C content of the genomic DNA of strain VG341 was 67.7 mol%. The whole-cell sugar pattern contained ribose, rhamnose, arabinose and galactose. On the basis of phenotypic and genetic data, eight strains (VG341, WS4684, WS4769, WS 4882, WS4883, WS4901, WS4902 and WS4904) are proposed to be classified as members of a novel species in a new genus of the family , for which the name gen. nov., sp. nov. is proposed. The type strain is VG341 (=WS4900=DSM 100885=LMG 29089) and seven additional strains are WS4684, WS4769, WS4882, WS4883, WS4901, WS4902 and WS4904. Furthermore, we propose the reclassification of as comb. nov.
