摘要: A novel aerobic, Gram-negative bacterial strain, designated KU41E(T), which degrades p-n-nonylphenol, was isolated from seawater obtained the coastal region of Ishigaki Island, Japan. Cells are motile, curved rods with a single polar flagellum. Strain KU41E(T) grew at 20-35 °C, pH 7.0-8.0, in presence 1.0-4.0% NaCl. The predominant respiratory lipoquinone ubiquinone-8, and major cellular fatty acids were summed feature 3 (C(15:0) iso 2OH and/or C(16:1) ω7c, 28.4%), C(18:1) ω7c (19.8%), C(16:0) (17.0%). DNA G + C content 48.6 mol%. 16S rRNA gene sequence analysis indicated that strain is affiliated order Alteromonadales within class Gammaproteobacteria most closely related to Pseudoteredinibacter isoporae SW-11(T) (93.6% similarity) Teredinibacter turnerae T7902(T) (91.9% similarity). On basis physiological, chemotaxonomic, phylogenetic data, suggested represent species new genus, for name Maricurvus nonylphenolicus gen. nov., sp. nov. proposed. type M. (=JCM 17778(T)).
