Abstract:
A novel, Gram-stain-negative, non-motile, rod-shaped yellow bacterium, designated VBW088 T was isolated from a shallow water hydrothermal vent in Espalamaca in the Azores. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain VBW088 T clustered with three type strains of species of the genus Vitellibacter and exhibited a sequence similarity of 97.3 % with Vitellibacter soesokkakensis RSSK-12 T . However, strain VBW088 T and V. soesokkakensis RSSK-12 T exhibited low DNA–DNA relatedness (12.7±3.5 %). Strain VBW088 T was positive for catalase and oxidase. Growth occurred at 10–37 °C, with the optimum at 30 °C, and at pH 6.0–8.0 (optimum pH 6.0) and in up to 5 % (w/v) NaCl with optimum growth at 1–2 % (w/v) NaCl. The major fatty acids ( 〉 10 %) were iso-C 15 : 0 (33.5 %) and iso-C 17 : 0 3-OH (32.0 %). The polar lipids detected in strain VBW088 T consisted of phosphatidylethanolamine, one unidentified aminolipid and three unidentified phospholipids. The DNA G+C content of strain VBW088 T was 36.7 mol%. On the basis of phylogenetic inference, DNA–DNA relatedness, chemotaxonomic analysis and physiological data, the isolate represents a novel species of the genus Vitellibacter , for which the name Vitellibacter nionensis sp. nov. is proposed, with the type strain as VBW088 T ( = KCTC 32420 T = MCC 2354 T ).
