从小麦根际土壤中分离到一株新的放线菌，命名为NEU-DSCPA1-4-4T。基于16S rRNA基因序列的系统发育分析表明，该菌应归属于链霉菌属。该菌株与其最近的亲缘关系加纳链霉菌DSM 40746T(16S rRNA基因序列相似性为97.7%)和绿色芽孢链霉菌DSM 40243T(97.6%)形成了一个单系分支。同样，化学分类数据，包括主要的菜籽酮、脂肪酸组成和极性脂谱，也支持菌株neau-DSCPA1-4-4T属于链霉菌属。然而，DNA-DNA亲缘关系和生理生化数据表明，NEAU-DSCPA1-4-4T菌株可以与其近缘菌株区分开来。因此，我们认为菌株neau-DSCPA1-4-4T是链霉菌属的一个新种，命名为Streptomycestriticsoli sp.11月提出以neau-DSCPA1-4-4T(=CCTCC AA 2017025T=DSM 105118T)为模式菌株。
A novel actinomycete, designated strain NEAU-DSCPA1-4-4T, was isolated from rhizosphere soil of wheat and characterized using a polyphasic approach. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the organism should be assigned to the genus Streptomyces. The strain formed a monophyletic clade with its closest relatives, Streptomyces ghanaensis DSM 40746T (97.7 % 16S rRNA gene sequence similarity) and Streptomyces viridosporus DSM 40243T (97.6 %). Similarly, chemotaxonomic data, including major menaquinones, fatty acid compositions and polar lipid profile, also supported the placement of strain NEAU-DSCPA1-4-4T in the genus Streptomyces. However, DNA-DNA relatedness, physiological and biochemical data showed that strain NEAU-DSCPA1-4-4T could be distinguished from its closest relatives. Therefore, we propose that strain NEAU-DSCPA1-4-4T represents a novel species of the genus Streptomyces, for which the name Streptomycestriticisoli sp. nov. is proposed, with NEAU-DSCPA1-4-4T (=CCTCC AA 2017025T=DSM 105118T) as the type strain.
