The aim of this work was the optimization of the enzyme hydrolysis of potato peel residues (PPR) for bioethanol production. The process included a pretreatment step followed by an enzyme hydrolysis using crude enzyme system composed of cellulase, amylase and hemicellulase, produced by a mixed culture of Aspergillus niger and Trichoderma reesei. Hydrothermal, alkali and acid pretreatments were considered...
In this paper, we report on the utilization of potato peel residues (PPR) as a substrate and support for the production of cellulase complexes by mono-and co-culture of Aspergillusniger ATCC 16404 and Trichodermareesei DSMZ 970 by solid state fermentation. A significant increase in cellulase production, especially CMC-ase, was obtained during co-culture compared to respective monocultures. The effect...
