A bacterial strain capable of degrading some monochlorinated dibenzofurans, designated RW16T, was isolated from aerobic River Elbe sediments. The strain was characterized based on 16S rRNA gene sequence analysis, DNA G+C content, physiological characteristics, polyamines, ubiquinone and polar lipid pattern and fatty acid composition. This analysis revealed that strain RW16T represents a novel species of the genus Sphingobium. The DNA G+C content of strain RW16T, 60.7 mol%, is the lowest yet reported for the genus. 16S rRNA gene sequence analysis placed strain RW16T as an outlier in the genus Sphingobium. The name Sphingobium aromaticiconvertens sp. nov. is proposed for this dibenzofuran-mineralizing organism, with type strain RW16T (=DSM 12677T=CIP 109198T).
从易北河需氧沉积物中分离出一株能够降解某些单氯代二苯并呋喃的细菌菌株，命名为RW16T。基于16S rRNA基因序列分析、DNA G+C含量、生理特性、多胺、泛醌和极性脂质模式以及脂肪酸组成对该菌株进行了表征。该分析表明，菌株RW16T代表鞘氨醇单胞菌属的一个新物种。菌株RW16T的DNA G+C含量为60.7 mol%，是该属中迄今报道的最低值。16S rRNA基因序列分析将菌株RW16T定位为鞘氨醇单胞菌属中的一个异常菌株。为此种二苯并呋喃矿化生物提出新物种名称芳香鞘氨醇单胞菌（Sphingobium aromaticiconvertens sp. nov.），模式菌株为RW16T（=DSM 12677T=CIP 109198T）。
