In the untreated grapes, the amounts of Penicillium sp. and Aspergillus sp.
showed alternating dominance patterns during storage. As shown in Fig. 8A and B, the amount of Aspergillus sp. was extremely high at day 20, while Penicillium sp. were almost non-detectable at this time point. On the contrary, the amount of Penicillium sp. increased greatly at day 60, whereas the amount of Aspergillus sp. decreased at the same time point
