委内瑞拉链霉菌 meaning in Chinese

streptomyces venezuelae

In this study , we attempted to construct an engineering strain producing only avermectin bl through the replacement of dna encoding dh2 - kr2 domains of the avermectin pks ( avedh2 - kr2 ) with dna encoding dh2 - kr2 domains from the pikromycin pks in s . avermitilis olm73 - 12 , producing only avermectins b and no oligomycin . gene replacement vector pxl201 ( pkc1139 : : 5 ' flank + pia : dh2 - kr2 + 3 ' flank ) was used to transform 5 . avermitilis olm73 - 12 protoplasts
我们以不产寡霉素而仅产阿维菌素b的工程菌olm73 - 12为出发菌株，用委内瑞拉链霉菌( streptomycesvenezuelae )中编码pikromycinpks模块2上完全活性的dh和酮基还原酶( kr )的dna区域对olm73 - 12染色体上编码阿维菌素pks模块2中dh和kr的区域进行取代，试图构建仅产b1组分的基因工程菌。
