Previous attempts to isolate auxotrophic mutants of A. nidulans produced only a limited range of phenotypes. The frequency of recovery of auxotrophic mutants was quantified following different mutagenic and selective treatments, and their yield improved by using a complete medium, additional mutagens, multiple cycles of penicillin enrichment and altered pre-enrichment starvation conditions.
