Factors affecting microcin E492 production.


The production of the antibiotic polypeptide microcin E492 by Klebsiella pneumoniae RYC492 has been studied in respect to the composition of the culture medium. The nature of both the carbon and nitrogen sources had a dramatic effect on the levels of the microcin detected in the supernants of the liquid cultures. Gluconeogenic precursors such as lactate or… (More)
