Flavitalea flava sp. nov., a bacterium isolated from a soil sample, and emended description of the genus Flavitalea
A Gram-stain negative strain, designated AN120636T, was isolated from a soil sample collected from Goesan-gun, Chungbuk, South Korea. The strain was strictly aerobic, with golden yellow-pigmented colonies on R2A agar. Cells were non-motile, long or short rods and some were observed to be coccal. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain AN120636T belongs to the genus Flavitalea in the family of Chitinophagacea, with Flavitalea populi (95.4%), Pseudoflavitalea soli (95.0%), Flavitalea gansuensis (94.7%) and Pseudoflavitalea rhizosphaerae (94.7%) as its close relatives. Growth was observed at 15–32 °C, pH 5.0–7.0 and in the absence of NaCl. The strain contained iso-C17:0 3-OH, iso-C15:1 G and iso-C15:0 as its major cellular fatty acids; phosphatidylethanolamine as the major polar lipid; MK-7 as its respiratory quinone; and the polyamine was homospermidine. The genomic DNA G+C content was 44.8 mol%. On the basis of the polyphasic evidence, strain AN120636T is considered to represent a novel species, for which the name Flavitalea flava sp. nov. is proposed. The type strain is AN120636T (=KCTC 52346T=CCTCC AB 2017174T).
