title: Flavobacterium suaedae sp. nov., an endophyte isolated from the root of Suaeda corniculata.
abstract: A Gram-stain-negative, non-motile, yellow, endophytic bacterium, designated G16-7T, was isolated from the root of Suaeda corniculata in Inner Mongolia, northern China. Phylogenetic analysis, based on the 16S rRNA gene, revealed that strain G16-7T belonged to the genus Flavobacterium, with highest sequence similarities to Flavobacterium rakeshii FCS-5T, Flavobacterium suzhouense XIN-1T, Flavobacterium beibuense F44-8T, Flavobacterium hauense BX12T and Flavobacterium shanxiense YF-2, ranging from 92.7 % to 94.9 %. The predominant fatty acids of strain G16-7T were iso-C15 : 0, summed feature 3 (consisting of C16 : 1ω7c and/or C16 : 1ω6c), iso-C17 : 0 3-OH and summed feature 9 (consisting of iso-C17 : 1ω9c and/or C16 : 0 10-methyl), while MK-6 was the major respiratory quinone. The major polar lipids were phosphatidylethanolamine, an unknown phospholipid, an unknown aminophospholipid, four unknown aminolipids and three unknown lipids. The genomic DNA G+C content of the strain was 34.2 mol%. Based on the phenotypic and genotypic characteristics, strain G16-7T is considered to represent a novel species of the genus Flavobacterium, for which the name Flavobacterium suaedae sp. nov. is proposed. The type strain is G16-7T ( = CGMCC 1.15461T = KCTC 42947T).
