Thalassocella blandensis gen. nov., sp. nov., a novel member of the family Cellvibrionaceae. Int J Syst Evol Microbiol. 2019 Dec 03;: Authors: Lucena T, Arahal DR, Sanz-Sáez I, Acinas SG, Sánchez O, Aznar R, Pedrós-Alió C, Pujalte MJ Abstract Strain ISS155T, isolated from surface Mediterranean seawater, has cells that are Gram-reaction-negative, motile, strictly aerobic chemoorganotrophic, oxidase-positive, unable to reduce nitrate to nitrite, and able to grow with cellulose as the sole carbon and energy source. It is mesophilic, neutrophilic, slightly halophilic and has a requirement for sodium and magnesium ions. Its 16S rRNA gene sequence places the strain among members of Cellvibrionaceae, in the Gammaproteobacteria, with Agarilytica rhodophyticola 017T as closest relative (94.3 % similarity). Its major cellular fatty acids are C18 : 1, C16 : 0 and C16 : 1; major phospholipids are phosphatidyl glycerol, phosphatidyl ethanolamine and an unidentified lipid, and the major respiratory quinone is Q8. The genome size is 6.09 Mbp and G+C content is 45.2 mol%. A phylogenomic analysis using UBCG merges strain ISS155T in a clade with A. rhodophyticola, Teredinibacter turnerae, Saccharophagus degradans and Agaribacterium haliotis type strain genomes, all of them possessing a varied array of carbohydrate-active enzymes and the potential for polysaccharide degradation. Average amino acid identity indexes determined against...
