Mutagenic Effect of Thymol in Conidia of the Fungus Aspergillus amstelodami

In the present research, five different sublethal concentrations (10, 15, 20, 25, 30) g/cm3 of thymol were tested for their ability to induce forward mutation resistant to the toxic base analogue (8-Azaadnine) in conidia of Aspergillus amstelodami by the growth-mediated method.
All five concentrations showed mutant frequencies significantly higher than the spontaneous one, (the negative control). but significance of the mutagenic effect was found in the last two concentrations (25, 30) g/ cm3.
