摘要A novel Gram-stain-negative, rod-shaped, facultatively anaerobic, oxidase-negative and catalase-positive bacterium, designated JZ3C29(T), was isolated from a saltern located in Feicheng, PR China. JZ3C29(T) was tolerant of moderately saline conditions. Optimal growth occurred at 40 degrees C (range 20-50 degrees C) and pH 7.5-8.5 (range pH 7.0-9.0) with 8-10% (w/v) NaCl (range 2-16 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that JZ3C29(T) shared highest similarity with Gracilimonas tropica CL-CB462(T) (90.5 %), Gracilimonas mengyeensis YIM J14(T) (90.5 %) and Gracilimonas rosea CL-KR2(T) (90.4 %) and less than 90.0% similarity with other species of the phylum Bacteroidetes. The isolate formed a novel genuslevel clade in the recently described family Balneolaceae. The polar lipid profile of the novel isolate consisted of diphosphatidylglycerol, phosphatidylethanolamine, three unidentified glycolipids, four unidentified phospholipids and two unidentified lipids. The dominant cellular fatty acids (> 10 %) were summed feature 3 (C-16 : 1 omega 7c and/or iso-C-15 : 0 2-OH) and iso-C-15 : 0 and the sole respiratory quinone was menaquinone 7 (MK-7). The DNA G+C content of JZ3C29(T) was 44.4 mol%. On the basis of these phenotypic and phylogenetic data, JZ3C29(T) should be classified as representing a novel genus and species within the family Balneolaceae, for which the name Rhodohalobacter halophilus gen. nov., sp. nov. is proposed. The type strain is JZ3C29(T) (= MCCC 1H00131(T) = KCTC 52046(T) = JCM 31413(T)).
