title: Filimonas aurantiibacter sp. nov., an orange-pigmented bacterium isolated from lake water and emended description of the genus Filimonas.
abstract: A Gram-stain-negative bacterium was isolated from Lake Michigan water. 16S rRNA gene sequence analysis revealed that strain 1458T had a sequence similarity to Filimonas lacunae YT21T, Sediminibacterium goheungense HME7863T, Parasegetibacter terrae SGM2-10T, Sediminibacterium ginsengisoli DCY13T, Terrimonas ferruginea DSM 30193T, Lacibacter cauensis NJ-8T, Flavihumibacter solisilvae 3-3T, Parasegetibacter luojieneis RHYL-37T, Vibrionimonas magnilacihabitans MU-2T and Parafilimonas terrae 5GHs7-2T with values of 93.4, 92.3, 91.9, 91.9, 91.8, 91.6, 91.6, 91.6, 91.5 and 90.4 %, respectively. The primary cellular fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 1G and summed feature 3 (iso-C15 : 0 2-OH/C16 : 1ω7c). The primary polar lipids were phosphatidylethanolamine and an unidentified polar lipid only detectable after total polar lipid staining. The quinone system was menaquinone MK-7, and in the polyamine pattern, sym-homospermidine was predominant. Additional phenotypic characteristics included growth at 15 to 40 °C and pH 5.0 to 8.0, a salt tolerance range of 0 to 2.0 % (w/v), production of orange cell-bound pigment flexirubin, and gliding motility. After phenotypic, chemotaxonomic and molecular analyses, strain 1458T was identified as a novel species of the genus Filimonas, for which the name Filimonas aurantiibacter sp. nov. is proposed. The type strain is 1458T (=NRRL B-65305T=LMG 29039T). An emended description of the genus Filimonas is also provided.
