ABSTRACT
A Gram-stain-negative, rod-shaped, strictly aerobic, motile bacterial strain, designated TP162T, was isolated from a seamount near the Yap Trench in the tropical western Pacific. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain TP162T was related to the genus Pseudoalteromonas and had highest 16S rRNA gene sequence similarities with the type strains Pseudoalteromonas shioyasakiensis SE3T (98.2 %), Pseudoalteromonas lipolytica LMEB 39T (97.7 %), Pseudoalteromonas arabiensis k53T (97.4 %) and Pseudoalteromonas aliena KMM 3562T (97.2 %). The predominant cellular fatty acids were summed feature 3 (composed of iso-C15 0 2-OH and/or C16 1ω7c), C17 1ω8c and C16 0. The quinone system for strain TP162T comprised predominantly ubiquinone-8, and the polar lipid profile contained phosphatidylethanolamine, phosphatidylglycerol, one unidentified phospholipid and four unidentified lipids. The genomic DNA G+C content of strain TP162T was 46.7 mol%. Strain TP162T shared 28 % DNA-DNA relatedness with P.shioyasakiensis JCM 18891T, 21 % with P. lipolytica JCM 15903T, 35 % with P.arabiensis JCM 17292T and 18 % with P.aliena LMG 22059T. Combined data from phenotypic, chemotaxonomic, phylogenetic and DNA-DNA relatedness studies demonstrated that strain TP162T is a representative of a novel species of the genus Pseudoalteromonas, for which we propose the name Pseudoalteromonas profundi sp. nov. (type strain TP162T=KACC 18554T=CGMCC 1.15394T).
