Abstract
A Gram-stain-negative, aerobic, rod-like, motile by peritrichous flagella and moderately halophilic bacterium, designated strain B6(T), was isolated a deep-sea sediment collected from the South Atlantic Ocean. The isolate grew with 0.5-15 % (w/v) NaCl, at 4-37 °C and pH 5.0-8.5 and showed a high tolerance to zinc, manganese, cobalt and copper ions. The major fatty acids were C16 : 0, C19 : 0 cyclo ω8c, C12 : 0 3-OH and C12 : 0. The predominant ubiquinone was Q-9. The genomic DNA G+C content was 61.1 mol%. Phylogenetic analysis based on 16S rRNA gene comparisons indicated that strain B6(T) belonged to the genus Halomonas, and the closest relative was Halomonas xinjiangensis TRM 0175(T) (96.1 %). Based upon the phenotypic, chemotaxonomic and genetic data, strain B6(T) represents a novel species from the genus Halomonas, for which the name Halomonas zincidurans sp. nov. is proposed. The type strain is B6(T) ( = CGMCC 1.12450(T) = JCM 18472(T)).

Halomonas nanhaiensis sp. nov., a halophilic bacterium isolated from a sediment sample from the South China Sea. Antonie Van Leeuwenhoek 2013; 103:997-1005. [PMID: 23314928 DOI: 10.1007/s10482-013-9879-3] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2012] [Accepted: 01/07/2013] [Indexed: 10/27/2022]
Abstract
A novel Gram-negative, aerobic, slightly halophilic, yellow-pigmented, oxidase-negative, Voges-Proskauer positive, non-spore-forming bacterium, designated YIM M 13059(T), was isolated from a sediment sample collected from the South China Sea at a depth of 310 m. Optimal growth was found to occur at 28-30 °C, pH 7.0 and in the presence of 3-4 % (w/v) NaCl. Cells were observed to be rod-shaped and motile by peritrichous flagella. The polar lipids of strain YIM M 13059(T) were found to be diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, a ninhydrin-positive phospholipid, one glycolipid and two unknown phospholipids. The predominant respiratory quinone was determined to be Q-9. The major fatty acids were identified as C18:1 ω7c, C16:1 ω6c/C16:1 ω7c, C16:0 and C12:0 3-OH. The genomic DNA G+C content was determined to be 54.4 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the isolate belongs to the genus Halomonas in the family Halomonadaceae. The 16S rRNA gene sequence similarities between strain YIM M 13059 (T) and the type strains of members of the genus Halomonas were in the range 93.3-98.3 %. However, the levels of DNA-DNA relatedness values between YIM M 13059 and the type strains of the most closely related species, Halomonas zhangjiangensis, Halomonas variabilis, Halomonas neptunia, Halomonas boliviensis and Halomonas sulfadieris were 50.2 ± 0.68 %, 46.8 ± 1.9 %, 28.5 ± 0.74 %, 42.9 ± 0.55 % and 37.1 ± 0.68 %, respectively. Based on phylogenetic, chemotaxonomic and phenotypic data, the strain YIM M 13059(T) is proposed to represent a novel member of the genus Halomonas, with the name Halomonas nanhaiensis sp. nov. The type strain is YIM M 13059(T) (=JCM 18142(T) =CCTCC AB 2012911(T)).

Abstract
Halomonas smyrnensis AAD6(T) is a Gram-negative, aerobic, exopolysaccharide-producing, and moderately halophilic bacterium that produces levan, a fructose homopolymer with many potential uses in various industries. We report the draft genome sequence of H. smyrnensis AAD6(T), which will accelerate research on the rational design and optimization of microbial levan production.
