1株抗真菌放线菌菌株YIM31530T的多相分类研究

 从云南丽江玉龙雪山采集的土壤样品中分离到1株诺卡菌形稀有放线菌YIM31530T.该菌株具有很强的抗灰霉病、稻纹枯病活性.通过对其进行的包括形态、生理生化特性、细胞壁化学组分以及16SrDNA序列等方面的多相分类研究,确定其为高丽菌属的1个新种,将其命名为抗菌高丽菌(Kribbella antibiotica sp.nov.).该菌株在大多数培养基上生长良好,气生菌丝黄白色,基内菌丝浅黄色至黄白色.气生菌丝和基内菌丝多分枝,常断裂成不规则的杆状体,不游动.

A study on polyphasic taxonomy of one antifungal actinomycete strain YIM31530T

One nocardioform rare actinomycete strain YIM31530^T,which had strong activity for inhibiting botrytis sp.,Rhizoctonia solani,Pyricularia oryzae,was isolated from a soil sample collected from Yulong Mountain in Lijiang,Yunnan Province.Based on our polyphasic studies,including its morphology,physiological and biochemical characteristics,chemotaxonomy and 16S rDNA sequence analysis,it was proposed it as a new species of genus Kribbella and named it as Kribbella antibiotica sp.nov..Strain YIM31530^T grew well on most test media.Aerial mycelium were yellow white and substrate mycelium were pale yellow to yellow white.Aerial mycelium and substrate mycelium were extensively branched and they often fragment into rod-shaped elements.They are non-motile.
