Pilot-scale bioconversion of rice and sunflower agro-residues into medicinal mushrooms and laccase enzymes through solid-state fermentation with Ganoderma lucidum

Solid-state fermentation was evaluated at the pilot-scale for the bioconversion and valorization of rice husks and straw (RSH), or sunflower seed hulls (SSH), into medicinal mushrooms and crude extracts, with laccase activity. The average mushroom yield was 56 kg dry weight per ton of agro-residues. Laccase activity in crude aqueous extracts showed its maximum value of 10,927 U kg−1 in RSH (day 10, Exudate phase) and 16,442 U kg−1 in SSH (day 5,...
