Algoriphagus trabzonensis sp. nov., isolated from freshwater, and emended description of Algoriphagus alkaliphilus Inan, Kadriye and Kacagan, Murat and Ozer, Aysegul and Osman Belduz, Ali and Canakci, Sabriye,, 65, 2234-2240 (2015), doi = https://doi.org/10.1099/ijs.0.000246, publicationName = Microbiology Society, issn = 1466-5026, abstract= A Gram-staining-negative, non-motile, catalase- and oxidase-positive strain, designated MS7T, was isolated from freshwater of a river near Trabzon, Turkey. Its taxonomy was investigated using a polyphasic approach. The strain grew optimally at 28 °C and pH 7.5 and in the presence of 2.0 % NaCl. 16S rRNA gene sequence analysis revealed that the strain belonged to the genus Algoriphagus; strain MS7T showed highest sequence similarity to the type strains of Algoriphagus alkaliphilus (97.3 %), Algoriphagus terrigena (96.8 %), Algoriphagus jejuensis (96.2 %), Algoriphagus boritolerans (96.1 %) and Algoriphagus aquatilis (95.8 %). The major fatty acids of strain MS7T were iso-C15 : 0 (30.14 %) and summed future 9 (10-methyl C16 : 0 and/or iso-C17 : 1 ω9c 18.75 %). Polar lipid analysis revealed phosphatidylethanolamine, a variety of unidentified lipids, an unidentified aminophospholipid, an unidentified phospholipid and an unidentified aminolipid. The major isoprenoid quinone was MK-7.The DNA G+C content of MS7T was 41.6 mol%, a value consistent with that of members of the genus Algoriphagus. The level of DNA–DNA relatedness between strain MS7T and A. alkaliphilus LMG 22694T was 41 %, which is clearly below the 70 % threshold accepted for species delineation. Thus, our results support the placement of strain MS7T within a separate and previously unrecognized species. On the basis of these data, the strain is considered to represent a novel species of the genus Algoriphagus, for which the name Algoriphagus trabzonensis sp. nov. is proposed. The type strain is MS7T ( = NCCB 100372T = LMG 26290T). An emended description of A. alkaliphilus is also provided., language=, type=
