Abstract excerpt
The effect of the iron content of the medium on the yield of the peptide antibiotic microcin 25 was examined; synthesis was optimal in minimal media and was reduced by adding iron. Escherichia coli AY25, the wild-type producer of the antibiotic, showed a 95% decrease in microcin yield when grown in minimal medium containing 10 microM iron (high iron) as compared to 0.2 microM (low iron). Addition of chelators to...
