<i>Acinetobacter zhairhuonensis</i> sp. nov., isolated from sediments of the East China Sea.

ABSTRACT: A novel aerobic bacterial strain, designated as Acinetobacter zhairhuonensis sp. nov. A7.4^T, was isolated from East China Sea sediments near Zhairuo island. Cells were Gram-stain-negative, non-motile short rods, forming milky, moist colonies. Growth occurred at 10-35 °C, pH 6.0-9.0 and 0-5% NaCl concentrations (w/v). Strain A7.4^T was catalase-positive and oxidase-negative. Major fatty acids (>10%) included summed feature 3 (C_16:1 ω7c/C_16 :1 ω6c), C_18:1 ω9c and C_16:0. The polar lipid profile comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, two phospholipids and two aminolipids. Ubiquinone Q-9 and Q-8 predominated. The genome (3.57 Mb, 41.3 mol% GC) included one chromosome and a plasmid.
