The ability of strains of the Arthrinium genus to inhibit microbial development has been previously described. In the present work different periods of mutagenic treatment using ultraviolet light, and of nitrosoguanidine treatment, on strains of Arthrinium were investigated. With nitrosoguanidine treatment the survival rate ranged from 2.17 to 8.78%. Mutant strains were only obtained with a higher antibiotic production in comparison with the wild-strain, when the mutagenic agent was UV light.
