Two actinomycete strains, NEAU-C11 and NEAU-C8, isolated from rhizosphere soil and wheat root, respectively, collected from Langfang, Hebei Province, China. A polyphasic study was carried out to establish the taxonomic position of the two strains. Morphological and chemotaxonomic characteristics of the isolates coincided with the genus Glycomyces. Sequences analysis of the 16S rRNA gene also showed that the organisms belong to the genus Glycomyces and Glycomyces algeriensis is the highest sequence match for both strains. Furthermore, a combination of DNA-DNA hybridization results and some differential physiological and biochemical properties indicated that they were distinguishable from the phylogenetically closest relatives. Therefore, the two strains represent a novel species, for which the name Glycomycesrhizosphaerae sp. nov. is proposed. The type strain is NEAU-C11 (=CGMCC 4.7396=DSM 104646).
两株放线菌菌株，NEAU-C11和NEAU-C8，分别从中国河北省廊坊市采集的根际土壤和小麦根部分离得到。开展了多相分类研究以确定这两株菌株的分类地位。分离菌株的形态学和化学分类学特征与糖霉菌属相符。16S rRNA基因序列分析也表明这些菌株属于糖霉菌属，且两株菌株与阿尔及利亚糖霉菌的序列匹配度最高。此外，DNA-DNA杂交结果以及一些不同的生理生化特性表明，它们与系统发育关系最近的亲缘种有所区别。因此，这两株菌株代表一个新物种，提议将其命名为根际糖霉菌（Glycomycesrhizosphaerae sp. nov.）。模式菌株为NEAU-C11（=CGMCC 4.7396=DSM 104646）。
