Abstract

Aspergillus awanori was subjected to chemical mutagenesis using ethyl methanesulfonate at different concentrations (0.5%, 1.0%, 1.5%) at different exposure time (30, 60, 90 minutes). Only 31 mutants were isolated and all exhibited lower protein contents than the wild type. The protein contents of the isolates ranted from 20.36% to 34.43%, which are significantly lower than that, the wild type (36.43%). In addition to lower Protein contents, the mutants also showed lower mycelial production (1.450. to 3.74g/1) than the wild type (3.02g/1). Furthermore, it was observed that the reduction in protein contents seems to be associated with the decrease in mycelial production.
