Abstract
A novel, Gram-stain-negative, motile, flagellated, aerobic, rod-shaped (0.5–0.7 µm wide and 1.0–1.2 µm long) and faint-yellow strain, designated ALS 84T, was isolated from marine sediment sampled at Ailian bay, Rongcheng, PR China. Growth occurred in the presence of 1–3 % (w/v) NaCl (optimum, 2 % NaCl), at pH 4.0–8.0 (pH 6.0–7.0) and at 8–30 °C (28 °C). The genome size was 4.37 Mbp. The G+C content of the genomic DNA was 33.6 mol%. The results of phylogenetic analysis based on 16S rRNA gene sequences suggested that strain ALS 84T belongs to the genus Flavicella within the family Flavobacteriaceae , and is most closely related to Flavicella marina (95.6 % similarity). The major fatty acids (>10 %) were iso-C15 : 0 3-OH (22.9 %), iso-C15 : 0 (14.0 %) and C16 : 0 (10.9 %). The major polar lipids were phosphatidylethanolamine and three unidentified lipids. Menaquinone-6 (MK-6) was identified as the respiratory quinone. On the basis of the phenotypic, phylogenetic and chemotaxonomic data obtained in the study, strain ALS 84T is considered to represent a novel species of the genus Flavicella , for which the name Flavicella sediminum sp. nov. is proposed. The type strain of the novel species is strain ALS 84T (=KCTC 62398T=MCCC 1K03480T).
