Planctobacterium marinum gen. nov., sp. nov., a new member of the family Alteromonadaceae isolated from seawater Sheu, Der-Shyan and Sheu, Shih-Yi and Lin, Kai-Rou and Chen, Yuh-ling Lee and Chen, Wen-Ming,, 67, 974-980 (2017), doi = https://doi.org/10.1099/ijsem.0.001726, publicationName = Microbiology Society, issn = 1466-5026, abstract= A bacterial strain designated K7T was isolated from the South China Sea and characterized using a polyphasic taxonomic approach. Cells of strain K7T were Gram-stain-negative, aerobic, poly-β-hydroxybutyrate-accumulating, motile by means of a monopolar flagellum, non-spore forming rods surrounded by a thick capsule and forming yellow colonies. Growth occurred at 4–35 °C (optimum, 25–30 °C), at pH 5.0–9.0 (optimum, pH 7.0) and with 0.5–10 % (w/v) NaCl [optimum, 1–4 % (w/v)]. The predominant fatty acids were summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and C18 : 1ω7c. The major isoprenoid quinone was Q-8 and the DNA G+C content was 46.5 mol%. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmonomethylethanolamine, one uncharacterized phospholipid, two uncharacterized aminophospholipids and five uncharacterized lipids. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain K7T formed a distinct lineage with respect to closely related genera in the family Alteromonadaceae . Strain K7T was most closely related to Aestuariibacter , Aliiglaciecola , Paraglaciecola and Glaciecola , and the levels of 16S rRNA gene sequence similarity with respect to the type species of related genera were less than 95 %. On the basis of the genotypic and phenotypic data, strain K7T represents a novel species of a new genus of the family Alteromonadaceae , for which the name Planctobacterium marinum gen. nov., sp. nov. is proposed. The type strain of Planctobacterium marinum is K7T (=BCRC 80901T=LMG 28835T=KCTC 42657T)., language=, type=
