sp. nov. a novel species on the borderline of the genus No Access

Abstract

A Gram-reaction-negative bacterial strain, designated Kb22, was isolated from agricultural soil and characterized using a polyphasic approach to determine its taxonomic position. On the basis of 16S rRNA gene sequence analysis, the strain shows highest similarity (94.39 %) to M-SX103. The highest average nucleotide identity value (71.83 %) was found with T5-12, and the highest amino acid identity value (66.65 %) was found with HAL-9. Cells are aerobic, non-motile rods. The isolate was found to be positive for catalase and oxidase tests. The assembled genome of strain Kb22 has a total length of 4,06 Mb, the DNA G+C content is 38.1 mol%. The only isoprenoid quinone is menaquinone 7 (MK-7). The major fatty acids are iso-C (28.4%), summed feature 3 (C ω7 and/or iso-C 2-OH) (25.7 %) and iso-C 3-OH (19.7 %). Based on phenotypic characteristics and phylogenetic results, it is concluded that strain Kb22 is a member of the genus and represents a novel species for which the name sp. nov. is proposed. The type strain of the species is strain Kb22 (=LMG 31574=NCAIM B.02638).
