Evaluation of the in vitro antagonism
Yeast inoculum was prepared in YPD broth and incubated on a reciprocal shaker at 180 strokes/min at 28 ± 2 °C for 24 h. A loop full of inoculum was transferred onto potato dextrose agar (PDA) (Difco, USA) by streaking and the plate culture was incubated at 25 °C for 48 h. To evaluate the control of fungal growth by yeast, an assay in which yeast and fungi were grown side by side was set up, as described by Rosa et al. (2010). A control plate was prepared with only fungal inoculation. The experiment was performed with three replicates, incubating the plates at 25 °C. Mycelial growth was measured at 3, 5, and 7 d of incubation.
