*3.2. Cultivation of P. sapidus*

*P. sapidus* (Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH, DSMZ, strain no. 2866) was pre-grown on 1.5% (*w*/*v*) agar plates with standard nutrient liquid (SNL) medium and maintained at 4 ◦C until use [39]. For pre-cultivation, 1 cm<sup>2</sup> of grown agar was transferred to 100 mL SNL medium and homogenized using an Ultraturrax homogenizer (ART Prozess- & Labortechnik, Müllheim, Germany). The pre-cultures were incubated for 5 days at 150 rpm and 24 ◦C. Afterwards, 6.5 g of pre-grown mycelium was used to inoculate 250 mL SNL. The main culture was incubated at 150 rpm and 24 ◦C. After six days, the mycelium was separated from the culture supernatant by centrifugation (5000× *g*, 4 ◦C, 15 min) and lyophilized as described elsewhere [42].
