Initial screening experiments revealed the suitability of brewer’s spent grain extract (BSGE) and diluted wine distillery effluent (WDE) as the sole carbon sources for significant mycelial mass production.

Considerably higher biomass and concentrations of total glucans, α-glucans and β-glucans were determined in macrofungi cultivated in BSGE compared to WDE. Agitated BSGE-based cultures of Schizophyllum commune resulted in the maximum biomass synthesis (27.6 g/L), while the highest total glucans of 70.8 % w/w with a β-glucan content of 57.2 % w/w were determined for G. lingzhi, when the culture was also agitated.

The hierarchical ZSM-5 was prepared using a double template method, aiming for micro and mesoporous systems developed in the structure. The as-prepared ZSM-5 were modified with Mn3O4 through incipient wetness impregnation with Mn2+ solution followed by calcination at 550 °C.
