A yellow-coloured bacterium, T41(T), was isolated from a soil sample of a subtropical rainforest in Nepal. Cells were Gram-reaction-positive, aerobic, non-motile, short rods. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain formed a cluster with Terrimonas ferruginea, Terrimonas lutea, Niabella soli, Flavisolibacter ginsengiterrae, Flavisolibacter ginsengisoli, Niastella yeongjuensis and Niastella koreensis in the phylum Bacteroidetes. The strain showed the highest sequence similarity to the type strain of Terrimonas lutea (93.2 %). The major isoprenoid quinone was MK-7 and the predominant cellular fatty acids (>10 %) were iso-15 : 0 (33.8 %), iso-15 : 1 G (13.3 %) and iso-17 : 0 3-OH (12.9 %). The DNA G+C content was 48.1 mol%. On the basis of phenotypic and phylogenetic data and genomic distinctiveness, strain T41(T) represents a novel species in a new genus in the phylum Bacteroidetes, for which the name Flavihumibacter petaseus gen. nov., sp. nov. is proposed. The type strain of Flavihumibacter petaseus is strain T41(T) (=CGMCC 1.7723(T) =NBRC 106054(T)).
从尼泊尔亚热带雨林的土壤样本中分离到一株呈黄色的细菌，命名为 T41(T)。细胞革兰氏阳性反应，需氧，不运动，短杆状。基于 16S rRNA 基因序列的系统发育分析表明，该菌株与 Terrimonas ferruginea、Terrimonas lutea、Niabella soli、Flavisolibacter ginsengiterrae、Flavisolibacter ginsengisoli、Niastella yeongjuensis 和 Niastella koreensis 一起在厚壁菌门中形成一个聚类。该菌株与 Terrimonas lutea 模式株的序列相似度最高（93.2%）。主要类异戊二烯醌为 MK-7，主要细胞脂肪酸（>10%）为 iso-15:0（33.8%）、iso-15:1 G（13.3%）和 iso-17:0 3-OH（12.9%）。DNA G+C 含量为 48.1mol%。基于表型和系统发育数据以及基因组的独特性，菌株 T41(T)代表厚壁菌门中一个新属的新种，将其命名为 Flavihumibacter petaseus gen. nov.，sp. nov.。Flavihumibacter petaseus 的模式菌株为 T41(T)（=CGMCC 1.7723(T)=NBRC 106054(T)）。
