Isolation and Identification of the Plasmid DNA in Three Micromonospora Strains Used in Production and Investigation of Their Functions

GUAN Yu-xia,LIU Zhi-qiongCollege of Biological Science and Technology,Fuzhou University,Fuzhou 350002,China  
The gentamicin producer Micromonospora purpurea,the micromicin and gentamicin producer M.echinospora and the sisomicin producer M.inyoensis were used as the study materials and their plasmid DNA was isolated and identified.The results showed that the plasmid DNA in the three strains was related to spore and pigment production and unrelated to antibiotics production,suggesting that the genes of antibiotics production in them were located on their chromosome DNA.This work may be considered to have laid foundation for the study of the genetic characters of their chromosome DNA and raising antibiotics yield.
