摘要：
The present invention relates to a method for selectively enhancing the production of factors A.sub.2 and/or A.sub.3 of antibiotic A/16686 either to isolate these single components or to enrich the complex in one or both the above components, which comprises adding an appropriate precursor of the desired antibiotic factor to an A/16686 producing culture during fermentation.
