放线菌菌株 YIM 90001(T) 和 YIM 90005(T) 是在从中国西部新疆省采集的土壤样品中的淀粉酪蛋白琼脂 [20% (w/v) NaCl，pH 7.0] 上分离得到的。两种分离株均为需氧且革兰氏阳性。基质菌丝体被破碎，气生菌丝体在 Czapek 培养基上发育良好。气生菌丝成熟时形成长孢子链，其中有分枝的短孢子链或长孢子链，直至弯曲，孢子不活动。根据代谢、化学分类学和分子分析结果，这两个分离株被鉴定为普拉瑟菌属的两个新种，菌株YIM 90001(T) (= IDSM 44617(T) = CCTCC AAOO 1015(T)) 命名为 Prauserella halophila，菌株 YIM 90005(T) (= DSM) 命名为 Prauserella alba。建议44590(T) CCTCC AA001016(T))。
The actinomycete strains YIM 90001(T) and YIM 90005(T) were isolated on starch-casein agar [20 % (w/v) NaCl, pH 7.0] from a soil sample collected from Xinjiang Province in the west of China. The two isolates were aerobic and Gram-positive. The substrate mycelium was fragmented and an aerial mycelium was well developed on Czapek medium. The aerial myceliurn formed long spore chains with branched short or long spore chains at maturity, which were straight to flexuous, and spores were non-motile. Based on the results of metabolic, chemotaxonomic and molecular analyses, the two isolates were identified as two new species of the genus Prauserella, for which the names Prauserella halophila for strain YIM 90001(T) (= IDSM 44617(T) = CCTCC AAOO 1015(T)) and Prauserella alba for strain YIM 90005(T) (= DSM 44590(T) CCTCC AA001016(T)) are proposed.
