Abstract:
Two novel Gram-negative, oxidase- and catalase-positive, rod-shaped bacterial strains, designated YCSA28 T and YCSA39, were isolated from sediment of Daqiao saltern, Jimo, Qingdao, on the east coast of China. The two strains grew optimally at 28–30 °C, at pH 7.5 and in the presence of 7–8 % (w/v) NaCl. They were assigned to the genus Halomonas , class Gammaproteobacteria , based on 16S rRNA gene sequence analysis. The major cellular fatty acids of the two strains were C 18 : 1 ω7 c (42.9 %), C 16 : 0 (23.1 %) and C 16 : 1 ω7 c /ω6 c (18.0 %), and Q-9 was the major ubiquinone. The G+C content of the DNA of strains YCSA28 T and YCSA39 was 63.7 and 63.9 mol%, respectively. The predominant respiratory lipoquinone, cellular fatty acid profiles and DNA G+C content of strains YCSA28 T and YCSA39 were consistent with those of recognized species of the genus Halomonas . Levels of DNA–DNA relatedness between strains YCSA28 T and YCSA39, between YCSA28 T and Halomonas ventosae Al12 T , and between YCSA39 and H. ventosae Al12 T were 95, 45 and 50 %, respectively. Together, these data indicated that strains YCSA28 T and YCSA39 represent a single novel species of the genus Halomonas , for which the name Halomonas daqiaonensis sp. nov. is proposed. The type strain is YCSA28 T ( = CGMCC 1.9150 T = NCCB 100305 T = MCCC 1B00920 T ).
