Abstract

Abstract : A yellow-pigmented bacterial strain, designated T13 T, was isolated from the rhizosphere soil of Alhagi sparsifolia collected from Xinjiang, PR China. Cells were rod-shaped, Gram-stain-negative, aerobic and gliding. Strain T13 T grew optimally at 25–30 °C and pH 7.0–8.0 with a NaCl tolerance of 0–2 % on Reasoner's 2A agar. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain T13 T belonged to the genus Flavobacterium within the family Flavobacteriaceae and was closely related to Flavobacterium nitrogenifigens KCTC 42884 T with a similarity value of 97.4 %. The major polar lipid was phosphatidylethanolamine; the only respiratory quinone was MK-6, and the polyamine profile contained sym -homospermidine as the major polyamine and a trace amount of spermidine. The major fatty acids were iso-C15 : 0, C16 : 1 ω7 c and summed feature 3 (comprising C16 : 1 ω7 c or C16 : 1 ω6 c ). The G+C content of the genomic DNA was 34.1 mol%. It is concluded from the phenotypic and genotypic data that strain T13 T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium ustbae sp. nov. with the type strain T13 T (=KCTC 62874 T =ACCC 60126 T ) is proposed.
