| Abstract |
A novel bacterium designated SSM4.2T was isolated from seaweed of Gouqi Island, which is the center of the Zhoushan fishing ground in the East China Sea. Strain SSM4.2T was Gram-stain-negative, bright yellow-pigmented, short rod-shaped, non-flagellated, non-spore forming, aerobic and motile by gliding. Growth was observed at 4-37 °C (optimum 25-30 °C), pH 6.0-8.0 (optimum pH 7.0) and 0-2.0% (w/v) NaCl (optimum 0%) concentration. The strain was catalase- and oxidase-positive. Menaquinone-6 (MK-6) was found as the sole respiratory quinone and zeaxanthin as the main carotenoid pigment. The predominant fatty acids (≥ 10%) were iso-C15:0, iso-C15:1 G, iso-C17:0 3-OH and summed feature 3 (C16:1 ω7c /C16:1 ω6c). The major polar lipid was phosphatidylethanolamine (PE). The genome size was 5.7 Mbp. The DNA G + C content was 34.1 mol%. 16S rRNA gene sequence revealed that strain SSM4.2T belongs to the genus Flavobacterium and shares high-sequence similarity with F. limi KACC 18851T (98.1%), F. hydrophilum KACC 19591T (97.6%), F. defluvii KCTC 12612T (97.1%), F. cheongpyeongense KACC 19592T (97.0%) and F. fluviatile KCTC 52446T (96.9%). Strain SSM4.2T had 73.2-84.6% average nucleotide identity and 19.1-29.4% digital DNA-DNA hybridization values with its closest type strains. Based on its phenotypic, chemotaxonomic, phylogenetic and genomic features, strain SSM4.2T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium ajazii sp. nov. is proposed. The type strain is SSM4.2T (= KCTC 72807T = MCCC 1K04370T).
