英文摘要A Gram- stain- negative, aerobic, motile, catalase- positive, oxidase- positive, short rod- shaped marine bacterium, designated as YIC-827T, was isolated from Qingdao, Shandong Province, China. The results showed that cells of strain YIC-827T could grow optimally at 25-35 degrees 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-827T was a member of the genus Pseudoalteromonas. The closest relative to this strain was Pseudoalteromonas ruthenica KMM 300T, 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-827T 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 16:0 , C 18:1 omega 7c and C 16:1 omega 7c/ C16:1 omega 6c. 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 T represents a novel species of the genus Pseudoalteromonas with the name Pseudoalteromonas qingdaonensis sp. nov. The type strain of P. qingdaonensis sp. is strain YIC-827T (=MCCC 1K08807T=CGMCC 1.62085T=KCTC 8212T).
