YIM M 10366（T）、YIM M 10378（T）和YIM M 10400（T）菌株是从中国南海西沙群岛的海洋沉积物中分离得到的。所有三种分离物能够在pH 7.0、28-37 °C和0-3%（w/v）NaCl下最佳生长。16 S rRNA基因序列的比较表明，这些菌株是链霉菌属的成员，表现出中等高的16 S rRNA基因序列相似性的97.0-98.8%的最密切相关的链霉菌属的成员。形态特征、生理特征和全细胞糖和磷脂的组成与链霉菌属的诊断特征一致，但仍允许在三种菌株及其邻居之间进行区分。根据16 SrRNA基因序列分析、DNA-DNA亲缘关系、表型特征和化学分类学数据，将菌株YIM M 10366（T）、YIM M 10378（T）和YIM M 10400（T）鉴定为链霉菌属的3个新种，其中命名为食糖链霉菌Streptomyces glycovorans sp. nov.（模式菌株YIM M 10366（T）=DSM 42021（T）=CCTCC AA 2010005（T）），锡山链霉菌，新种（模式菌株YIM M 10378（T）= DSM 42022（T）=CCTCC AA 2010006（T））和深海链霉菌（Streptomyces abyssalis sp. nov.）（模式菌株YIM M 10400（T）=DSM 42024（T）= CCTCC AA 2010008（T））。
Strains YIM M 10366(T), YIM M 10378(T) and YIM M 10400(T) were isolated from marine sediments collected from the Xisha Islands in the South China Sea. All three isolates were able to grow optimally at pH 7.0, 28-37 °C and 0-3% (w/v) NaCl. Comparison of 16S rRNA gene sequences showed that these strains are members of the genus Streptomyces, exhibiting moderately high 16S rRNA gene sequence similarities of 97.0-98.8% to members of the most closely related Streptomyces species. Morphological characteristics, physiological characteristics and compositions of whole-cell sugars and phospholipids are consistent with the diagnostic characteristics of the genus Streptomyces, but still allowed differentiation amongst the three strains and their neighbours. Based on 16S rRNA gene sequence analysis, DNA-DNA relatedness, phenotypic characteristics and chemotaxonomic data, strains YIM M 10366(T), YIM M 10378(T) and YIM M 10400(T) were identified as members of three novel species of the genus Streptomyces, for which the names Streptomyces glycovorans sp. nov. (type strain YIM M 10366(T) =DSM 42021(T) =CCTCC AA2010005(T)), Streptomyces xishensis sp. nov. (type strain YIM M 10378(T) = DSM 42022(T) =CCTCC AA 2010006(T)) and Streptomyces abyssalis sp. nov. (type strain YIM M 10400(T) =DSM 42024(T) = CCTCC AA 2010008(T)) are proposed.
