Abstract
A novel strictly aerobic, Gram-stain-positive, rod-shaped, motile, endospore-forming, white-coloured bacterium, designated strain MFER-1T, was isolated from a fermented liquor of wild grasses sampled in the Republic of Korea. The respiratory quinone of strain MFER-1T was menaquinone-7 and its major cellular fatty acids were anteiso-C15 : 0 (55.3 %), iso-C16 : 0 (17.5 %) and C16 : 0 (12.1 %). The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, four unidentified aminophospholipids and an unidentified phospholipid. The 16S rRNA gene sequence of strain MFER-1T showed similarity of 98.1 % to 'Cohnella cholangitidis' 1 605-214T and below 98.0 % sequence similarity to the other Cohnella species. The phylogenomic tree indicated that strain MFER-1T formed a reliable cluster with several Cohnella species. The estimated genome size of strain MFER-1T was 8.52 Mb. Genomic DNA G+C content was 50.7mol%. The orthologous average nucleotide identity, digital DNA-DNA hybridization and amino acid identity values of strain MFER-1T with the most closely related species 'Cohnella cholangitidis' 1 605-214T were 78.7, 23.0 and 79.6 %, respectively. Based on the phenotypic, chemotaxonomic and phylogenetic results, strain MFER-1T should represent a novel species of the genus Cohnella, for which the name Cohnella herbarum sp. nov. is proposed, with strain MFER-1T (=KACC 21 257T=NBRC 114 628T) as the type strain.
