- sp. nov., isolated from the intestines of . Lin, Xingyue Zhang, Shuqian Fang, Suyun Hu, Xiaoke Ma, Lianju Pseudoalteromonas Phylogeny RNA, Ribosomal, 16S Fatty Acids Base Composition DNA, Bacterial China Nucleic Acid Hybridization Bacterial Typing Techniques Sequence Analysis, DNA Animals Intestines A Gram-stain-negative, aerobic, motile, catalase-positive, oxidase-positive, short rod-shaped marine bacterium, designated as YIC-827, was isolated from Qingdao, Shandong Province, China. The results showed that cells of strain YIC-827 could grow optimally at 25-35 °C, pH 6.5-7.5 and 2-7% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequence showed that the strain YIC-827 was a member of the genus . The closest relative to this strain was KMM 300, with a similarity of 98.39%. The digital DNA-DNA hybridization value between the new isolate and phylogenetically related species is 19.6%. Strain YIC-827 could decompose sodium alginate, casein and esters (Tween 20, Tween 40, Tween 60 and Tween 80), but could not hydrolyse starch, cellulose and DNA. The fatty acid profile of a strain consists of a large number of C, C ω7c and C ω7c/ ω6c. The G+C content of the DNA of this strain was determined to be 48.93%. Based on phenotypic characteristics, phylogenetic analysis and DNA-DNA correlation data, the strain YIC-827 represents a novel species of the genus with the name sp. nov. The type strain of sp. is strain YIC-827 (=MCCC 1K08807=CGMCC 1.62085=KCTC 8212).
