Title Marinilabilia rubra sp. nov., isolated from a marine solar saltern.
Journal Int. J. Syst. Evol. Microbiol.
Abstract A novel cherry-red-pigmented, Gram-stain-negative, gliding, facultatively anaerobic and rod-shaped bacterium, designated strain WTE16T, was isolated from a sediment sample taken from a marine solar saltern of Wendeng, China (36° 59' 56.49'' N 122° 1' 38.84'' E). The novel isolate was able to grow at 20-40 °C (optimum 33 °C), at pH 6.0-9.0 (optimum pH 7.0) and with 1.0-12.0 % (w/v) NaCl (optimum 3.0-5.0 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that the most closely related validly published species is Marinilabilia salmonicolor JCM 21150T (96.0 % similarity). Average nucleotide identity, average amino acid identity, percentage of conserved proteins and digital DNA-DNA hybridization values between strain WTE16T and Marinilabilia salmonicolor JCM 21150T were 73.8 %, 73.5 %, 63.4 % and 19.5-24.2 %, respectively. The genomic DNA G+C content of strain WTE16T was 40.8 mol%. Chemotaxonomic analysis showed that the sole respiratory quinone was menaquinone 7 (MK-7), and the major fatty acids included iso-C15 : 0 and anteiso-C15 : 0. The polar lipid profile of strain WTE16T included phosphatidylethanolamine, three unidentified phospholipids and three unidentified lipids. On the basis of its phylogenetic, phenotypic, chemotaxonomic, genotypic and genomic characteristics, strain WTE16T is suggested to represent a novel species of the genus Marinilabilia, for which the name Marinilabilia rubra sp. nov. is proposed. The type strain is WTE16T (=KCTC 62599T=MCCC 1H00311T).
