In order to enhance the production of glucose oxidase (GOD), random mutagenesis of Aspergillus tubingensis CTM 507 was performed using the chemical and physical mutagens: nitric acid and UV irradiation, respectively.
The majority of the isolated mutants showed good GOD production, but only some mutants presented a significant overproduction, as compared with the parent strain.
The selected mutants (19 strains), showing an overproduction larger than 200%, are quite stable after three successive subcultures.
Among these, six strains revealed an important improvement in submerged fermentation.
The insecticidal activity of GOD produced by the wild and the selected mutant strains was evaluated against the third larval instars of E.
kuehniella.
Mutant strains U11, U12, U20, and U21, presenting the most important effect, displayed an LC50 value of 89.00, 88.51, 80.00, and 86.00 U/cm2, respectively, which was 1.5-fold more important than the wild strain (61 U/cm2).
According to histopathology observations, the GOD enzyme showed approximately similar damage on the E.
kuehniella midgut including rupture and disintegration of the epithelial layer and cellular vacuolization.
The data supports, for the first time, the use of GOD as a pest control agent against E.
kuehniella.
