The mutation frequency mostly was related to the dose of
As described earlier by Afsharmanesh
et al. (2013), a significant reduction (P ¼ 0.01) in A. flavus R5
growth using a dual culture assay was observed in 45 bacterial
mutants (out of 500), when strain UTB1was irradiated at doses of 2,
2.5 and 3 KGy showing 3-4 log kill.
