PREPARATION OF NOCARDICIN A

摘要

PURPOSE:To obtain nocardicin A, by culturing microorganisms, which have the ability to produce norcardicin A only in the presence of nocardicin G (G), in a medium containing G. CONSTITUTION:Microorganisms having the ability to produce nocardicin A only in the presence of nocardicin G (G) are cultured in a medium containing G. Nocardia uniformis subsp. tsuyamanensis (N) may be cited as the microorganisms. Nocardia uniformis subsp. tsuyamanensis No.T-9 may be cited as artificial variation strains derived from ATCC21806 strains of N.
