Abstract
Conjugal transfer of the small plasmid pUB110 between Bacillus subtilis strains was studied under conditions of microcosms with sterile and nonsterile soil. Plasmid transfer proved to be possible after soil inoculation with vegetative partner cells or with their spores. Plasmid transfer occurred at temperatures of 30 degrees C and 22-23 degrees C.
摘要
在含有无菌和非无菌土壤的微观世界条件下，研究了枯草芽孢杆菌菌株间小质粒pUB110的接合转移。结果表明，用营养型伴侣细胞或其孢子接种土壤后，质粒转移是可能的。质粒转移发生在30摄氏度以及22 - 23摄氏度的温度下。
