Flavitalea flava sp. nov., a bacterium isolated from a soil sample, and emended description of the genus Flavitalea

A Gram-stain negative strain, designated AN120636^T, 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 AN120636^T 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-C_17:0 3-OH, iso-C_15:1 G and iso-C_15:0 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 AN120636^T is considered to represent a novel species, for which the name Flavitalea flava sp. nov. is proposed. The type strain is AN120636^T (=KCTC 52346^T=CCTCC AB 2017174^T).
