Summary
Aspergillus awamori and Trichoderma reesei were used, separately and in mixed culture, to convert apple distillery waste into microbial biomass. Overall, the use of mixed culture had considerable advantages, the positive properties of each species being retained. The effect of Aspergillus is evident in improved filtration and chemical oxygen demand reduction, as well as in the β-glucosidase synthesis. Trichoderma, on the other hand, contributes to good fibre degradation, protein enrichment of the biomass and cellulolytic, xylanolytic and pectolytic activities in the filtrates.
