A new bacterial strain NY5(T), belonging to the genus Pseudohalioglobus, was isolated from marine sediment collected in Weihai, China. It is a Gram-stain-negative, strictly aerobic, non-motile, rod-shaped bacterium.
A Gram-stain-negative, strictly aerobic, non-motile and rod-shaped bacterial strain, designated NY5(T), was isolated from marine sediment collected from coastal area in Weihai, China (122 degrees 07 ' 38.80 '' E, 37 degrees 33 ' 57.60 '' N). Cells of strain NY5(T) were 0.6-0.7 mu m width and 1.9-2.0 mu m length, catalase-positive and oxidase-positive. Growth of NY5(T) was observed at 25-37 degrees C (optimum, 28 degrees C) and pH 6.5-9.5 (optimum, pH 7.5-8.0) and in the presence of 0.5-7.0% (w/v) NaCl (optimum, 2.0%). The isoprenoid quinone was Q-8 and the predominant fatty acids were summed feature 8 (C-18:1 omega 7c and/or C-18:1 omega 6c), summed feature 3 (C-16:1 omega 7c and/or C-16:1 omega 6c) and C-17:1 omega 8c. Diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol were the major polar lipids. The DNA G+C content of strain NY5(T) was 60.1%. Strain NY5(T) showed the highest 16S rRNA gene sequence similarity (98.2%) with Pseudohalioglobus lutimaris followed by Parahaliea aestuarii (96.9%), Parahaliea maris (96.7%), Parahaliea mediterranea (95.9%), and Halioglobus japonicus (94.9%). Given these phenotypic and chemotaxonomic properties and phylogenetic analyses, strain NY5(T) was considered to represent a novel species of the genus Pseudohalioglobus, for which the name Pseudohalioglobus sediminis sp. nov. is proposed. The type strain is NY5(T) (=KCTC 72416(T)=MCCC 1H00401(T)).
