A Gram-negative, moderately halophilic bacterium, designated YIM 91125(T), was isolated from a salt lake in Xinjiang province, north-west China. The isolate grew at salinities in the range 1-20% (w/v) and at 4-45 degrees C. Optimal growth occurred at 37 degrees C, pH 7.5 and 5-10% (w/v) NaCl. Cells were short rods motile by means of single polar flagella. The major fatty acids were C(18:1)omega7c, C(16:0), C(19:0) cyclo omega8c and C(12:0) 3-OH. The DNA G+C content was 60.8 mol%. The predominant respiratory quinone was Q-9. A comparison of 16S rRNA gene sequences revealed its relationship to Halomonas species, its closest neighbours being Halomonas pantelleriensis (95.9% similarity to the type strain) and Halomonas muralis (95.4 % similarity). On the basis of chemotaxonomic, phylogenetic and phenotypic evidence, strain YIM 91125(T) represents a novel member of the genus Halomonas, for which the name Halomonas lutea sp. nov. is proposed. The type strain is YIM 91125(T) (=KCTC 12847(T) =CCTCC AB 206093(T)).

Species of the genus Halomonas are halophilic and their flexible adaption to changes of salinity and temperature brings considerable potential biotechnology applications, such as degradation of organic pollutants and enzyme production. The type strain Halomonas lutea YIM 91125(T) was isolated from a hypersaline lake in China. The genome of strain YIM 91125(T) becomes the twelfth species sequenced in Halomonas, and the thirteenth species sequenced in Halomonadaceae.
