Aequorivita capsosiphonis sp. nov., isolated from the green alga Capsosiphon fulvescens, and emended description of the genus Aequorivita Park, Seong Chan and Baik, Keun Sik and Kim, Mi Sun and Kim, Seon Suk and Kim, Seok Ryel and Oh, Myung-Joo and Kim, Duwoon and Bang, Byung-Ho and Seong, Chi Nam,, 59, 724-728 (2009), doi = https://doi.org/10.1099/ijs.0.004119-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= A marine bacterial strain, designated A71T, was isolated from marine algae collected from the South Sea, Republic of Korea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain A71T belonged to the family Flavobacteriaceae and was closely related to Aequorivita antarctica SW49T (96.5 % sequence similarity). Cells of strain A71T were Gram-negative, aerobic, oxidase-negative, catalase-positive, yellow/orange-pigmented and non-motile. The major fatty acids were iso-C15 : 0 (20.6 %), iso-C17 : 1 ω9c (13.3 %), anteiso-C15 : 0 (13.1 %), iso-C17 : 0 3-OH (12.7 %) and summed feature 3 (comprising iso-C15 : 0 2-OH and/or C16 : 1 ω7c; 6.6 %). The DNA G+C content was 36.9 mol%. Several phenotypic characteristics served to differentiate the isolate from recognized members of the genus Aequorivita. Data from this polyphasic study clearly demonstrated that strain A71T represents a novel species of the genus Aequorivita. The name Aequorivita capsosiphonis sp. nov. is proposed, with strain A71T (=KCTC 22183T =JCM 15070T) as the type strain. In addition, an emended description of the genus Aequorivita is presented., language=, type=
