From my laboratory experiment, A. versicolor is able to grow on PDA agar but the growth is really slow compared to A. flavus and A. niger. 

It takes 2 weeks to make the A. versicolor cover 2/3 of the agar surface (in petri dish) while it only take 6 days for A. flavus and A. niger to do so. Does anyone have suggestion on how to fasten A. versicolor growth?
