Shewanella gelidii sp. nov., isolated from the red algae Gelidium amansii, and emended description of Shewanella waksmanii Wang, Yan and Chen, Hongli and Liu, Zhenhua and Ming, Hong and Zhou, Chenyan and Zhu, Xinshu and Zhang, Peng and Jing, Changqin and Feng, Huigen,, 66, 2899-2905 (2016), doi = https://doi.org/10.1099/ijsem.0.001075, publicationName = Microbiology Society, issn = 1466-5026, abstract= A novel Gram-stain-negative, straight or slightly curved rod-shaped, non-spore-forming, facultatively anaerobic bacterium with a single polar flagellum, designated RZB5-4T, was isolated from a sample of the red algae Gelidium amansii collected from the coastal region of Rizhao, PR China (119.625° E 35.517° N). The organism grew optimally between 24 and 28 °C, at pH 7.0 and in the presence of 2–3 % (w/v) NaCl. The strain required seawater or artificial seawater for growth, and NaCl alone did not support growth. Strain RZB5-4T contained C16 : 1ω7c and/or C16 : 1ω6c, C16 : 0 and iso-C15 : 0 as the dominant fatty acids. The respiratory quinones detected in strain RZB5-4T were ubiquinone 7, ubiquinone 8, menaquinone 7 and methylmenaquinone 7. The polar lipids of strain RZB5-4T comprised phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmonomethylethanolamine, one unidentified glycolipid, one unidentified phospholipid and one unknown lipid. The DNA G+C content of strain RZB5-4T was 47 mol %. Phylogenetic analysis based on 16S rRNA and gyrase B (gyrB) gene sequences showed that strain RZB5-4T belonged to the genus Shewanella , clustering with Shewanella waksmanii ATCC BAA-643T. Strain RZB5-4T exhibited the highest 16S rRNA gene sequence similarity value (96.6 %) and the highest gyrB gene sequence similarity value (80.7 %), respectively, to S. waksmanii ATCC BAA-643T. On the basis of polyphasic analyses, strain RZB5-4T represents a novel species of the genus Shewanella , for which the name Shewanella gelidii sp. nov. is proposed. The type strain is RZB5-4T (=JCM 30804T=KCTC 42663T=MCCC 1K00697T)., language=, type=
