Aflatoxins in mutants of Aspergillus flavus
Copyright policy )Aflatoxins in mutants of Aspergillus flavus
Mutants ofAspergillus flavus were recovered following the irradiation of conidia with ultraviolet light. Analysis of the mutants for aflatoxins B1, B2, G1, and G2 indicated a wide range of variability in aflatoxin levels. None of the isolates produced the G toxins, and four produced little or no aflatoxin B2. Production of B1 and B2 by the mutants ranged from 1.3 µ;g/ml to 967 µg/ml and zero to 30 µg/ml, respectively. The correlation between production of B1 and B2 was statistically significant. There was no apparent correlation between nutritional requirement or conidial color and aflatoxin production.
