文摘

A new aerobic, Gram stain-negative, oxidase- and catalase- positive, ovoid or rod-shaped bacterial strain, designated HTCJW17T, was isolated from a sediment collected from the South China Sea and subjected to a polyphasic taxonomic characterization. The isolate forms small, creamy-white, opaque and circular colonies on agar plates. Growth occurs between 15 and 45?°C, 1-?% (w/v) NaCl and pH 6-. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain HTCJW17T belongs to the family Kordiimonadaceae of the order Kordiimonadales, with highest sequence similarity to Kordiimonas gwangyangensis GW14-5T (91.1?%). The major fatty acids were identified to be summed feature 8 (C18:1 ω7c/ω6c; 56.6?%), C14:0 (8.5?%), C14:0 2-OH (8.4?%), summed feature 3 (C16:1 ω7c/C16:1 ω6c; 6.2?%), and C16:0 (5.2?%). The polar lipids were determined to be phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, six unidentified glycolipids and two unidentified phospholipids. The respiratory quinone was identified as ubiquinone Q-10. The genomic DNA G+C content was determined to be 56.3?mol%. On the basis of genotypic, chemotaxonomic and phenotypic distinctness, we propose a novel genus, Emcibacter gen. nov., with Emcibacter nanhaiensis sp. nov. as the type species. The type strain is HTCJW17T (=CGMCC 1.12471T?=?LMG 27419T?=?MCCC 1A06723T).
