Description A novel Gram-negative, non-spore forming, rod-shaped aerobic bacterium, designated SSW136T, was isolated from a surface seawater sample collected at Espalamaca (in Faial Island), Azores. Growth was found to occur from 10 to 37 ?C, pH 6.0?8.0, and with 2-11 % of NaCl. 16S rRNA gene sequence indicated that the strain SSW136T belongs to the family Rhodobacteraceae. Strain SSW136T exhibited 96.3, 95.9, 95.7 and 95.5 sequence similarity to the type strains Oceanicola litoreus M-M22T, Roseovarius aestuarii SMK-122T, Marivita geojedonensis DPG-138T, and Pseudoruegeria aquimaris SW-255T respectively. Neighbour-joining and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences revealed that strain SSW136T was affiliated to the family Rhodobacteraceae and formed a separate branch. The G+C content was 63.5 mol%. The major respiratory quinone was found to be Q-10. The polar lipids of strain SSW136T consisted of phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, two unidentified aminolipids and three unidentified phospholipids. The major fatty acids were C18:1 Omega7c (46.5 %), Cyclo-CCyclo-C19:0 Omega 8c (16.0 %) and C16:0 (12.8 %). On the basis of the morphological, genotypic, chemotaxonomic characteristics and low DNA?DNA relatedness, strain SSW136T is proposed to represent a novel genus and novel species, Nioella nitratireducens gen. nov., sp. nov., in the family Rhodobacteraceae. The type strain is SSW136T (=KCTC 32417T = NCIM 5499T)
