Acidiluteibacter ferrifornacis gen. nov., sp. nov., a new member of the Flavobacteriales from Tielu Harbour, Hainan, PR China. Int J Syst Evol Microbiol. 2020 Sep 23;: Authors: Gui X, Wu S, Huang F, Wang Y, He R, Zhao J Abstract A novel bacterial strain of the family 'Vicingaceae' was isolated from mangrove of Tielu Harbour, Hainan, PR China. Strain S-15T was a Gram-stain-negative, short-rod-shaped, yellow-pigmented that could grow at 10-42 °C (optimum, 26-35 °C), at pH 5.0-9.0 (optimum, pH 5.5) and in 0.5-10.0 % w/v sea salt (optimum, 3.5-4.0 %). Cells of strain S-15T were 0.9-1.4 µm long, 0.8-0.9 µm wide, catalase-positive and oxidase-positive. Colonies on modified marine agar 2216 were 0.5-2.0 mm in diameter after incubation for 72 h at 28 °C. Analysis of 16S rRNA gene sequences revealed that strain S-15T was most closely related to Vicingus serpentipes ANORD5T (89.8 %). The major respiratory quinone of strain S-15T was menaquinone MK-7, and the dominant fatty acids were C15:0 iso, C15:1 iso G and C17:0 iso 3-OH. The major polar lipids were two unidentified aminolipids, phosphatidylethanolamine and six unidentified lipids. Analyses showed that the genome size was 3.52 Mb and the DNA G+C content was 35.6 mol%, which were higher than V. serpentipes ANORD5T with 2.92 Mb genome size and 31.0 mol% G+C content, respectively. Based on morphological, physiological and phylogenetic data, strain S-15T is considered a type strai...
