Description of Kushneria aurantia gen. nov., sp. nov., a novel member of the family Halomonadaceae, and a proposal for reclassification of Halomonas marisflavi as Kushneria marisflavi comb. nov., of Halomonas indalinina as Kushneria indalinina comb. nov. and of Halomonas avicenniae as Kushneria avicenniae comb. nov.

Abstract >>
An aerobic, moderately halophilic, Gram-negative, motile, non-sporulating rod-shaped bacterium, designated strain A10(T), was isolated from the surface of leaves of the black mangrove Avicennia germinans and was subjected to a polyphasic taxonomic study. Strain A10(T) was able to grow at NaCl concentrations in the range 5-17.5 % (w/v) with optimum growth at 10 % (w/v) NaCl. Growth occurred at temperatures of 20-40 degrees C (optimal growth at 37 degrees C) and pH 5.5-8.5 (optimal growth at pH 7.0-8.0). The major respiratory quinone was ubiquinone 9. The major fatty acids were C(16 : 0), C(18 : 1)omega7c, C(19 : 0) cyclo omega8c and C(12 : 0) 3-OH. The polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, and unidentified phospholipids, glycolipids and an aminoglycolipid. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain A10(T) is closely related to Halomonas avicenniae MW2a(T) (95.7 % sequence similarity), Halomonas marisflavi SW32(T) (95.2 %) and Halomonas indalinina GC2.1(T) (95.0 %). Strain A10(T) formed a coherent phylogenetic branch with these three species, separated from other species of Halomonas and closely related genera (with 16S rRNA gene sequence similarities below 94.0 %). A complete 23S rRNA gene sequence comparison of strain A10(T) with closely related species confirmed the phylogenetic position of the novel isolate, forming a branch with the species Halomonas avicenniae, Halomonas indalinina and Halomonas marisflavi, separated from other species of the genera belonging to the family Halomonadaceae (showing sequence similarities below 91.7 %). DNA-DNA hybridization studies between strain A10(T) and Halomonas avicenniae MW2a(T), Halomonas marisflavi DSM 15357(T) and Halomonas indalinina CG2.1(T) were 21, 17 and 10 %, respectively. These levels of DNA-DNA relatedness were low enough to classify strain A10(T) as representing a genotypically distinct species. Overall, the phenotypic, genotypic, chemotaxonomic and phylogenetic results demonstrated that strain A10(T) represents a new genus and species. The name Kushneria aurantia gen. nov., sp. nov. is proposed, with strain A10(T) (=CCM 7415(T)=CECT 7220(T)) as the type strain. This is the type species of the new proposed genus, which belongs to the family Halomonadaceae. In addition, our data support the placement of the species Halomonas marisflavi, Halomonas indalinina and Halomonas avicenniae within this new genus, as Kushneria marisflavi comb. nov., Kushneria indalinina comb. nov. and Kushneria avicenniae comb. nov., respectively.

Halomonas marisflavae sp. nov., a halophilic bacterium isolated from the Yellow Sea in Korea.

International journal of systematic and evolutionary microbiology 51 (Pt 3)
PMID : 11411685 DOI  :   10.1099/00207713-51-3-1171    
Abstract >>
A halophilic Gram-negative bacterial strain, SW32T, which was isolated from a sample from the Yellow Sea of Korea, was subjected to a polyphasic taxonomic study. This organism grew optimally in the presence of 0.5-12% NaCl. On the basis of phenotypic and phylogenetic data, strain SW32T appeared to be a member of the genus Halomonas. Strain SW32T formed a distinct evolutionary lineage within the phylogenetic clade comprising Halomonas species and the genera Zymobacter and Carnimonas. The 16S rDNA sequence of strain SW32T contains 19 signature characteristics of the genus Halomonas and the family Halomonadaceae. Strain SW32T possessed a single polar flagellum, ubiquinone-9 as the predominant respiratory lipoquinone and C18:1, C16:0 and C16:1 omega7c and/or iso-C15:0 20H as the major fatty acids. The DNA G+C content was 59 mol%. Levels of 16S rDNA similarity between strain SW32T and the type strains of all validly described Halomonas species were 92.0-93.8%. Strain SW32T exhibited 16S rDNA similarity values of 92.7% to Zymobacter palmae IAM 14233T and 91.6% to Carnimonas nigrificans CECT 4437T. These data indicate that strain SW32T was related enough to members of the genus Halomonas to be placed as a new species within that genus. Therefore the name Halomonas marisflavae sp. nov. is proposed for strain SW32T. The type strain of the new species is strain SW32T (= KCCM 80003T = JCM 10873T).
