Abstract

A novel, halophilic, motile, rod-shaped, Gram-staining-negative and non-endospore forming bacterium, designated Cs25(T), was isolated from the rhizosphere of the halophyte Arthrocnemum macro stachyum growing in a tidal flat. Strain Cs25(T) was observed to be catalase-negative and oxidase-positive, and to hydrolyse hypoxanthine. Growth occurred from 15 to 40 degrees C, at pH 7.0-10.0 and with 1-11 % (w/v) NaCl. Q-10 was identified as the dominant ubiquinone, and the major cellular fatty acids were C-18 : 1 omega 7C, 11-methyl C-18 : 1 omega 7c, C-20 : 1 omega 7c and C-18 : 0. The polar lipids comprised phosphatidylmonomethylethanolamine, phosphatidylcholine, sulphoquinovosyldiacylglyceride, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolannine. The 16S rRNA gene showed 99.19, 98.6 and 98.59% sequence identity with Labrenzia alba DSM 18320(T), L. aggregata DSM 13394(T) and L. marina DSM 17023(T), respectively. Based on the phenotypic and molecular features and DNA DNA hybridization data, it is concluded that strain Cs25(T) represents a novel species for which the name Labrenzia salinasp. nov. is proposed. The type strain is Cs25(T) (=DSM 29163(T)=CECT 8816(T)).
