摘要:
A novel plasmid pEAP2, which was constructed from Bacillus sp. 170 chromosomal DNA carrying the gene for extracellular production of penicillinase and a vector plasmid pMB9. A novel microorganism, Escherichia coli HB101(pEAP2) carrying the plasmid pEAP2 and being capable of extracellular production of penicillinase. The method for cultivation of the microorganism is characterized by culturing it in the medium containing NaCl (or KCl) for 16-48 hours. According to this invention, useful high-molecular substances can be produced in a high yield.
