The individual colonies of a partially degenerated culture ofAspergillus versicolor vary widely in their ability to produce an antibiotic active againstTrichophyton rubrum . Mutagenic treatment with nitrous acid or ultraviolet light gave potent colonies. Nitrous acid gave better results in terms of stability and yield. This treatment may therefore prove useful in the regeneration of partially degenerated cultures.
