Abstract A strictly aerobic, Gram-negative, non-pigmented bacterial strain, designated LMEB 39(T), was isolated from a seawater sample collected from the Yangtze River estuary near the East China Sea and was examined physiologically, chemotaxonomically and phylogenetically. The novel isolate was motile by a single polar flagellum and positive for nitrate reduction and decomposition of casein, gelatin, Tween 20 and Tween 80, but negative for indole production. Chemotaxonomic analysis revealed ubiquinone-8 as the predominant respiratory quinone and phosphatidylethanolamine and phosphatidylglycerol as major polar lipids. The major fatty acids were C(16 : 1) ω 7c/iso-C(15 : 0) 2-OH, C(16 : 0), C(18 : 1) ω 7c, C(12 : 0) 3-OH, C(17 : 1)ω 8c and C(17 : 0). The genomic DNA G+C content was 42.3 mol%. Comparative 16S rRNA gene sequence analysis revealed that the isolate belongs to the genus Pseudoalteromonas. Strain LMEB 39(T) exhibited the closest phylogenetic affinity to Pseudoalteromonas byunsanensis JCM 12483(T) (97.4 % sequence similarity). The DNA-DNA reassociation values between strain LMEB 39(T) and P. byunsanensis JCM 12483(T) and Pseudoalteromonas undina DSM 6065(T) (97.2 % sequence similarity) were 31.7 and 30.3 %, respectively. On the basis of phenotypic and genotypic data, strain LMEB 39(T) represents a novel species of the genus Pseudoalteromonas, for which the name Pseudoalteromonas lipolytica sp. nov. is proposed; the type strain is LMEB 39(T) (=CGMCC 1.8499(T)=JCM 15903(T)).
