Ethanol, feed components and fungal biomass production from field beans (Vicia faba var. equina) seeds in an integrated process

The use of field beans, a non-food leguminous crop, was studied for ethanol, feed components and fungal biomass production. The seeds were hydrolyzed using enzymes or with combination of acid (H3PO4) and alkaline (Ca(OH)2) pretreatment and enzymatic hydrolysis. Fermentation by Saccharomyces cerevisiae, with or without removal of suspended solids, yielded 38.3–42.5 g L-1 ethanol (71.3–79.2% […]
