Description
Summary:Two isolates derived independently from raw refrigerated processing meat of bovine origin intended for the manufacture of Bologna-type cooked sausage could be distinguished from other known species in subsequent phylogenetic analyses. Comparison of the complete B gene sequences in combination with nearly complete 16S rRNA gene sequences revealed a separate branch within the group. In further analyses, comprising phenotypic and chemotaxonomic characterization as well as average nucleotide identity (ANI) values obtained from the draft genome assemblies, the two isolates could be distinguished from all so far published closely related species. The closest relative was DSM 3456 with ANI values of about 90.2 %. Other close neighbours were DSM 17535 (86.5 %), DSM 26521 (86.4 %), DSM 101070 (83.8 %), DSM 21104 (83.2 %), DSM 29166 (82.3 %), DSM 29165 (82.7 %) and DSM 6252 (81.9 %). The G+C contents of isolates TH39 and TH26 were both 58.2 mol%. The major cellular lipids of strain TH39 were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol; the major quinone was Q9 with small amounts of Q8. Based on these data, the isolates TH39 and TH26 (=DSM 107389=LMG 30831) represent a novel species within the genus for which the name sp. nov. is proposed. The type strain is TH39 (=DSM 107390 =LMG 30830 ).
