*2.1. Microbial Strains and Growth Conditions*

*Lactobacillus plantarum* UFG 121 was available at the Laboratory of Industrial Microbiology of the University of Foggia (Foggia, Italy) and routinely grown in de Man Rogosa Sharpe (MRS) broth (Oxoid, Basingstoke, UK) at 30 ◦C for 24 h.

Six filamentous fungi, namely *Penicillium roqueforti* CECT 20508, *Penicillium expansum* CECT 2278, *Penicillium chrysogenum* CECT 2669, *Aspergillus niger* CECT 2805, *Aspergillus flavus* CECT 20802, and *Fusarium culmorum* CECT 2148 were provided by the Spanish Type Culture Collection (CECT, Paterna, Spain). Fungal cultures were plated on malt extract agar (Oxoid) and incubated at 24 ◦C for 5 days.

The commercial fresh yeast *Saccharomyces cerevisiae* "Lievital" (Lessafre, Marcq-en-Baroeul, France) was resuspended in sterile saline solution, streaked on plates of yeast extract, peptone, dextrose (YPD, Oxoid), and incubated at 30 ◦C for 48 h. Then, a single colony was resuspended in YPD broth and incubated at 30 ◦C.
