Marinobacter xestospongiae sp nov isolated from the marine sponge xestospongia testudinaria collected from the red sea
International Journal of Systematic and Evolutionary Microbiology, 2012Co-Authors: Huixian Wu, Xiaojian Zhou, Li Miao, Hao Wang, Peiyuan QianAbstract:A Gram-negative, catalase- and oxidase-positive, non-sporulating, rod-shaped and slightly halophilic bacterial strain, designated UST090418-1611T, was isolated from the marine sponge Xestospongia testudinaria collected from the Red Sea coast of Saudi Arabia. Phylogenetic trees based on the 16S rRNA gene sequence placed strain UST090418-1611T in the family Alteromonadaceae with the closest relationship to the genus Marinobacter . The 16S rRNA gene sequence similarity between the strain and the type strains of recognized Marinobacter species ranged from 92.9 to 98.3 %. Although strain UST090418-1611T shared high 16S rRNA gene sequence similarity with Marinobacter mobilis CN46T, M. zhejiangensis CN74T and M. sediminum R65T (98.3, 97.4 and 97.3 %, respectively), the relatedness of the strain to these three strains in DNA–DNA hybridization was only 58, 56 and 33 %, respectively, supporting the novelty of the strain. In contrast to most strains in the genus Marinobacter , strain UST090418-1611T tolerated only 6 % (w/v) NaCl, and optimal growth occurred at 2.0 % (w/v) NaCl, pH 7.0–8.0 and 28–36 °C. The predominant cellular fatty acids were C12 : 0 3-OH, C16 : 0, C12 : 0 and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c). The genomic DNA G+C content was 57.1 mol%. Based on the physiological, phylogenetic and chemotaxonomic characteristics presented in this study, we suggest that the strain represents a novel species in the genus Marinobacter , for which the name Marinobacter xestospongiae sp. nov. is proposed, with UST090418-1611T ( = JCM 17469T = NRRL B-59512T) as the type strain.

Marinobacter mobilis sp. nov. and Marinobacter zhejiangensis sp. nov., halophilic bacteria isolated from the East China Sea.
International journal of systematic and evolutionary microbiology, 2020Co-Authors: Chun-sheng Wang, Junyi Yang, Min Wu, Xue-wei XuAbstract:Three Gram-negative, aerobic, motile, halophilic, rod-shaped strains (CN46(T), CN71 and CN74(T)) were isolated from sediment of the East China Sea and subjected to a polyphasic taxonomic study. Strains CN46(T) and CN71 had identical 16S rRNA gene sequences and phenotypic characteristics. Strain CN46(T) was moderately halophilic. Growth of strain CN46(T) was observed between 0.5 and 10.0 % (w/v) NaCl (optimal growth at 3.0-5.0 %) and between pH 6.5 and 9.0. Strain CN74(T) grew over a wider range of pH (pH 6.0-9.5); the optimum NaCl concentration for growth was 1.0-3.0 %. The major fatty acids of strain CN46(T) were C(16 : 1)omega9c, C(16 : 0) and C(12 : 0), whereas strain CN74(T) contained C(16 : 0), C(16 : 1)omega9c, C(18 : 1)omega9c and C(12 : 0). The DNA G+C contents of the three isolates were between 58.0 and 58.9 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strains CN46(T), CN71 and CN74(T) grouped together within the cluster of Marinobacter species. 16S rRNA gene sequence similarities of the three strains with the type strains of Marinobacter species ranged from 94.0 to 97.1 %. The DNA-DNA hybridization values of strain CN74(T) with strains CN46(T) and CN71 were 35.0 and 36.0 %, respectively. Levels of DNA-DNA relatedness between strains CN46(T) and CN74(T) and Marinobacter pelagius CGMCC 1.6775(T), Marinobacter gudaonensis CGMCC 1.6294(T) and Marinobacter koreensis DSM 17924(T) were 15.3-45.2 %. The results of DNA-DNA hybridizations, fatty acid analysis, and physiological and biochemical tests allowed genotypic and phenotypic differentiation of the isolates from closely related species. Two novel species are proposed, named Marinobacter mobilis sp. nov. (type strain CN46(T) =CGMCC 1.7059(T) =JCM 15154(T)) and Marinobacter zhejiangensis sp. nov. (type strain CN74(T) =CGMCC 1.7061(T) =JCM 15156(T)).

Marinobacter pelagius sp. nov., a moderately halophilic bacterium.
International journal of systematic and evolutionary microbiology, 2020Co-Authors: Xue-wei Xu, Yue-hong Wu, Chun-sheng Wang, Junyi Yang, Aharon Oren, Min WuAbstract:A Gram-negative, aerobic, neutrophilic, moderately halophilic bacterial strain, HS225(T), was isolated from seawater samples around the Zhoushan Archipelago, Zhejiang Province, China. The isolate grew optimally in media with 5.0 % NaCl, at pH 7.0-8.0 and at 25-30 degrees C. The predominant fatty acids were C(16 : 0)omega9c, C(16 : 0), C(12 : 0) 3-OH and C(18 : 1)omega9c. The genomic DNA G+C content was 59.0 mol%. Based on 16S rRNA gene sequence analysis, the isolate was found to be affiliated to the genus Marinobacter. Strain HS225(T) exhibited closest phylogenetic affinity to Marinobacter koreensis DD-M3(T) (98.1 % 16S rRNA gene sequence similarity). DNA-DNA relatedness data and DNA G+C contents as well as physiological and biochemical test results allowed the genotypic and phenotypic differentiation of strain HS225(T) from closely related species. Therefore, it is proposed that strain HS225(T) represents a novel species of the genus Marinobacter, for which the name Marinobacter pelagius sp. nov. is proposed. The type strain is HS225(T) (=CGMCC 1.6775(T) =JCM 14804(T)).

Marinobacter fuscus sp. nov., a marine bacterium of Gammaproteobacteria isolated from surface seawater.
International Journal of Systematic and Evolutionary Microbiology, 2018Co-Authors: Maripat Xamxidin, Hong Cheng, Fan-xu Meng, Yue-hong Wu, Chun-sheng Wang, Xue-wei XuAbstract:A Gram-stain-negative bacterium, designated NH169-3T, was isolated from a surface seawater sample of the South China Sea and subjected to a taxonomic polyphasic investigation. Strain NH169-3T was strictly aerobic, non-motile, non-spore-forming and rod-shaped. The colony was 1.0–2.0 mm in diameter after the growth on marine agar at 30 °C for 72 h. The centre of the colony was smooth, circular, convex and brown with a transparent periphery. Strain NH169-3T was able to grow at temperatures between 4–40 °C (optimum, 37 °C), pH 5.5–9.0 (pH 7.5) and with 0–12.5 % (w/v) NaCl (3.0 %). Chemotaxonomic analysis showed that the sole respiratory quinone of strain NH169-3T was ubiquinone 9; major fatty acids were C16 : 0 and C18 : 1 ω9c, and major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and one unidentified glycolipid. The DNA G+C content was 52.7 mol%. The comparison of 16S rRNA gene sequences showed that strain NH169-3T was closely related to Marinobacter shengliensis SL013A34A2T with a similarity of 98.0 %. Three phylogenetic trees reconstructed with neighbour-joining, maximum-parsimony and maximum-likelihood methods using 16S rRNA gene sequences showed that strain NH169-3T was grouped into a separated branch with M. shengliensis SL013A34A2T in a clade of the genus Marinobacter and closely related to Marinobacter halophilus JCM 30472T, Marinobacter vinifirmus DSM 17747T and Marinobacter hydrocarbonoclasticus DSM 8798T. Analyses of both phenotypic and phylogenetic properties have suggested that strain NH169-3T was distinctive from species with validly published names in genus Marinobacter . Thus, strain NH169-3T (=MCCC 1K03455T=KCTC 62226T) is proposed as a novel species in genus Marinobacter with the name Marinobacter fuscus sp. nov.

Marinobacter vinifirmus sp. nov., a moderately halophilic bacterium isolated from a wine-barrel-decalcification wastewater.
International journal of systematic and evolutionary microbiology, 2020Co-Authors: Pierrepol Liebgott, Laurence Casalot, Sebastien Paillard, Jean Lorquin, Marc LabatAbstract:A halophilic, Gram-negative, motile, non-sporulating bacterium designated strain FB1T was isolated from a wine-barrel-decalcification wastewater. The organism comprises straight rods and has a strictly respiratory metabolism with O2. Strain FB1T grows optimally at 20-30 degrees C and 5-6% NaCl. The predominant fatty acids were found to be C18:1omega9c (30.4%), C16:0 (25.7%), C12:0 3-OH (10.3%), C16:1omega9c (9.7%) and C16:1omega7c (8.4%). A phylogenetic analysis based on 16S rRNA gene sequences revealed that the strain forms a coherent cluster within the genus Marinobacter. The highest level of 16S rRNA gene sequence similarity (97.9%) exhibited by strain FB1T was with the type strain of Marinobacter excellens. However, the level of DNA-DNA relatedness between the novel strain and M. excellens CIP 107,686T was only 31.2%. The DNA G+C content of strain FB1T was 58.7 mol%. On the basis of phenotypic and genotypic characteristics, and also phylogenetic evidence, strain FB1T is considered to represent a novel species of the genus Marinobacter, for which the name Marinobacter vinifirmus sp. nov. is proposed. The type strain is FB1T (=DSM 17747T=CCUG 52119T).
