Abstract

Gram-stain-negative, aerobic, halophilic bacteria, designated SCM-1, LCM10-1 and CTBL-B-147, were isolated from modified half-strength SWM-III medium, PES medium and thalli after laboratory cultivation of a red alga, . Phylogenetic analysis of 16S rRNA gene sequences indicated that the new isolates were affiliated to the genus of the class , and the 16S rRNA gene sequence similarity of the new isolates with the closest related species, CH-B427, was 98.8 %. The DNA G+C contents of the new isolates were in the range of 61.4–62.3 mol%. DNA–DNA relatedness values of strain SCM-1 with other type strains of the genus were less than 15.9 %. The new isolates contained Q-10 as the predominant ubiquinone, phosphatidylcholine, phosphatidylglycerol, an unidentified amino lipid and an unidentified lipid as the main polar lipids, and Cω7, Cω7 and C as the major fatty acids (>10 % of the total). Strain SCM-1 could be differentiated from JCM 21792 by 35 morphological and phenotypic characteristics. On the basis of the phylogenetic, genetic and phenotypic properties of the new isolates, the name sp. nov. is proposed, with strain SCM-1 ( = LMG 27110 = NBRC 109054) as the type strain.
