Thalassobaculum salexigens sp. nov., a new member of the family Rhodospirillaceae from the NW Mediterranean Sea, and emended description of the genus Thalassobaculum Urios, Laurent and Michotey, Valérie and Intertaglia, Laurent and Lesongeur, Françoise and Lebaron, Philippe,, 60, 209-213 (2010), doi = https://doi.org/10.1099/ijs.0.011460-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= A novel Gram-negative bacteria, named CZ41_10aT, was isolated from coastal surface waters of the north-western Mediterranean Sea. Cells were motile, pleomorphic rods, 1.6 μm long and 0.7 μm wide and formed cream colonies on marine agar medium. The G+C content of the genomic DNA was 65 mol%. Phylogenetic analysis of 16S rRNA gene sequences placed the new isolate in the genus Thalassobaculum, a member of the family Rhodospirillaceae, class Alphaproteobacteria. Unlike Thalassobaculum litoreum CL-GR58T, its closest relative, strain CZ41_10aT was unable to grow anaerobically and did not exhibit nitrate reductase activity. On the basis of DNA–DNA hybridization, fatty acid content and physiological and biochemical characteristics, this isolate represents a novel species for which the name Thalassobaculum salexigens sp. nov. is proposed. The type strain is CZ41_10aT (=DSM 19539T=CIP 109064T=MOLA 84T). An emended description of the genus Thalassobaculum is also given., language=, type=
