The taxonomic position of bacterial strain 141T, isolated from the mangrove rhizosphere, has been clarified by phenotypic, chemotaxonomic and phylogenetic studies. The strain possesses wall chemotype IV, MK-9(H2) as the predominant menaquinone, relatively long-chain mycolic acids (56-64) carbon atoms) and straight-chain saturated and monounsaturated fatty acids with a small amount of tuberculostearic acid. The G+C content of the DNA is 66.8 mol%. Similarity values for genes encoding 16S rRNA indicated that strain 141T represents a new species within the genus Gordonia for which the name Gordonia rhizosphera sp. nov. is proposed. The type strain of G. rhizosphere is 141T (IFO 16068T).
通过表型、化学分类学和系统发育学研究，已明确了从红树林根际分离出的细菌菌株141T的分类地位。该菌株具有IV型细胞壁化学类型，以MK-9(H2)作为主要的甲基萘醌，含有相对长链的分枝菌酸（56 - 64个碳原子）以及直链饱和脂肪酸和单不饱和脂肪酸，并含有少量结核硬脂酸。DNA的G+C含量为66.8 mol%。编码16S rRNA的基因相似性值表明，菌株141T代表戈登氏菌属内的一个新物种，为此提出新名称戈登氏根际菌（Gordonia rhizosphera sp. nov.）。戈登氏根际菌的模式菌株是141T（IFO 16068T）。
