利用多相分类法对一株土壤放线菌的分类地位进行了评价。该生物，菌株J72，被发现具有化学和形态学特性与其归属Gordonia属一致。通过对扩增基因的直接测序，确定了该菌株几乎完整的16 S rDNA序列。供试菌株在戈登氏菌属的进化辐射范围内形成了一条独特的系统发育线，与戈登氏菌属的亲缘关系最近。聚异戊二烯类DSM 44302 T。菌株372的表型特征很容易将其与戈登氏菌属的代表物种区分开来。综合基因型和表型数据，菌株J72值得确认为戈登氏菌属的一个新种。新种命名为Gordonia sinesedis;模式菌株为J72 T（= DSM 44455 T = NCIMB 13802 T）。
The taxonomic position of an actinomycete isolated from soil was evaluated using a polyphasic approach. The organism, strain J72, was found to have chemical and morphological properties consistent with its assignment to the genusGordonia. A nearly complete 16S rDNA sequence of the strain was determined by direct sequencing of the amplified gene. The tested strain formed a distinct phylogenetic line within the evolutionary radiation occupied by the genusGordoniaand was most closely related toG. polyisoprenivoransDSM 44302T. The phenotypic profile of strain 372 readily distinguishes it from representatives of the validly described species ofGordonia. The combined genotypic and phenotypic data show that strain J72 merits recognition as a new species ofGordonia. The name proposed for the new species isGordonia sinesedis; the type strain is J72T(= DSM 44455T= NCIMB 13802T).
