Flavihumibacter soli sp. nov., Isolated from Soil. Curr Microbiol. 2020 Jun 29;: Authors: Seo YL, Jung J, Khan SA, Kim KH, Jeon CO Abstract A novel Gram-stain-positive, strictly aerobic, non-motile, rod-shaped bacterium, designated strain R14T was isolated from steep grove soil and taxonomically characterized using a polyphasic approach. Cells showed oxidase-negative and catalase-positive activities and grew at 25-37 °C (optimum, 30 °C), pH 5.0-8.0 (optimum, pH 6.5), and in the presence of 0-0.5% (w/v) NaCl (optimum, 0%). Phylogenetic trees based on 16S rRNA gene sequences revealed that strain R14T formed a phylogenetic lineage with Flavihumibacter genus members within the family Chitinophagaceae. Comparison of 16S rRNA gene sequences showed that strain R14T shared highest similarities with Flavihumibacter solisilvae 3-3T (97.5%), Flavihumibacter petaseus NBRC 106054T (96.7%), and Flavihumibacter stibioxidans YS-17T (96.1%). The G+C content of strain R14T calculated from its whole genome sequence was 44.6 mol%. Strain R14T contained menaquinone-7 and iso-C15:0, iso-C17:0 3-OH, C16:0, C15:1 ω6c, and iso-C15:0-G as the sole respiratory isoprenoid quinone and major cellular fatty acids, respectively. Major polar lipids consisted of phosphatidylethanolamine, two unidentified aminolipids, and four unidentified lipids. Based on phylogenetic, phenotypic, and chemotaxonomic characteristics of strain R14T, it could be concluded that str...
