摘要：

A highly efficient gene-cloning system for Micromonospora olivasterospora, a producer of the antibiotic fortimicin A (astromicin), suited to shotgun cloning has been developed. The system is supported by two new advancements accomplished in this study. One is the construction of novel plasmid vectors pMO116, pMO126, pMO133, pMO136, and pMO217, all consisting of replicons from newly found Micromonospora plasmids and selectable markers cloned from a neomycin-producing Micromonospora strain. The other advancement is the establishment of a new protocol for bacterial protoplasting in which some kinds of sugar alcohols are added in precultures. Such sugar alcohols were found to sensitize a wide taxonomical range of bacteria to lysozyme. The system is reproducible and reliable and has a high efficiency of more than 10(6) CFU/mu-g of DNA.
