Abstract:
A Gram-negative, motile, rod-shaped bacterial strain, HP15 T , was isolated from aggregates taken from surface waters of the German Wadden Sea (German Bight). Of 82 marine isolates, HP15 T was chosen for further study because of its high potential to induce production of transparent exopolymeric particles and aggregate formation while interacting with the diatom Thalassiosira weissflogii . HP15 T grew optimally at 34–38 °C and pH 7.0–8.5, and was able to tolerate salt concentrations of 0.5–20 % (w/v) NaCl. HP15 T was characterized chemotaxonomically by possessing ubiquinone-9 as the major respiratory lipoquinone, as well as C 16 : 0 , C 18 : 1 ω9 c and C 16 : 1 ω7 c /iso-C 15 : 0 2-OH as the predominant fatty acids. The DNA G+C content of strain HP15 T was 56.9 mol%. The closest relative based on 16S rRNA gene sequence analysis was the type strain of Marinobacter flavimaris , with 99 % similarity. Whole-genome relatedness values of HP15 T to the type strains of M. flavimaris , Marinobacter salsuginis , Marinobacter lipolyticus and Marinobacter algicola were less than 70 %, as determined by DNA–DNA hybridization. On the basis of phenotypic and chemotaxonomic properties as well as phylogenetic analyses, the isolate represents a novel species, Marinobacter adhaerens sp. nov.; the type strain is HP15 T ( = DSM 23420 T = CIP 110141 T ).
