链霉菌属一新亚种，拟命名为吸湿链霉菌亚种。yakushimaensis无性系种群。11月，是描述。土壤分离株7238可生产新型免疫抑制剂FR-900520。该生物的特点是其灰色的气生菌丝颜色，吸湿孢子团和螺旋状孢子链，孢子表面有疣状或多刺。它是非显色的。菌株7238表现出与抗真菌链霉菌和吸湿链球菌最密切相关的特征，尽管它们在生理特性和碳水化合物利用方面存在差异。在形态特征上，菌株7238不同于抗真菌链球菌，但与吸湿链球菌相似。这些差异不足以建立一个新物种。将7238号菌株作为吸湿菌种内的新亚种较为合适。链霉菌属一新亚种，拟命名为吸湿链霉菌亚种。yakushimaensis无性系种群。11月，是描述。土壤分离株7238可生产新型免疫抑制剂FR-900520。该生物的特点是其灰色的气生菌丝颜色，吸湿孢子团和螺旋状孢子链，孢子表面有疣状或多刺。它是非显色的。菌株7238表现出与抗真菌链霉菌和吸湿链球菌最密切相关的特征，尽管它们在生理特性和碳水化合物利用方面存在差异。在形态特征上，菌株7238不同于抗真菌链球菌，但与吸湿链球菌相似。这些差异不足以建立一个新物种。将7238号菌株作为吸湿菌种内的新亚种较为合适。
A new subspecies of the genus Streptomyces, the proposed name of which is Streptomyces hygroscopicus subsp. yakushimaensis subsp. nov., is described. Soil isolate, strain No. 7238, produces the novel immunosuppressants, FR-900520. The organism is characterized by its gray aerial mycelium color, hygroscopic spore mass and spiral spore chains with warty or spiny spore surfaces. It is nonchromogenic. Strain No. 7238 shows charactersitics most closely related to Streptomyces antimycoticus and S. hygroscopicus, although there are differences in physiological characteristics and carbohydrate utilization. In terms of morphological characteristics, strain No. 7238 is different from S. antimycoticus, but resembles S. hygroscopicus. The differences are not sufficient to establish a new species. It would be most suitable to designate strain No. 7238 as a new subspecies within the species of S. hygroscopicus.A new subspecies of the genus Streptomyces, the proposed name of which is Streptomyces hygroscopicus subsp. yakushimaensis subsp. nov., is described.
