Abstract:
A Gram-stain-negative, aerobic, rod-shaped, non-motile and pale yellow-pigmented bacterial strain, designated as HY03T, was isolated from mountain soil. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain HY03T belonged to the family Chitinophagaceae in the phylum Bacteroidetes and was most closely related to Flaviaesturariibacter amylovorans GCR0105T at a similarity of 95.4 %. The genomic DNA G+C content of strain HY03T was 43.2 mol%. The major fatty acids of the isolate were iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH. The polar lipid profile of strain HY03T consisted of the major compound phosphatidylethanolamine and moderate amounts of an unknown aminophospholipid, unknown phospholipids and unknown lipids. The predominant respiratory quinone was menaquinone 7 (MK-7). Phylogenetic, genotypic, phenotypic and chemotaxonomic characteristics indicated that strain HY03T represents a novel species within the genus Flaviaesturariibacter, for which the name Flaviaesturariibacter terrae sp. nov. is proposed. The type strain is HY03T (=KCTC 52511T=JCM 31723T).
