protein-extracted lucerne fibers (pelf) are an excellent lignocellulosic feedstock source in biomass conversion to the soluble sugars. pelf was hydrolyzed (85 carbohydrate conversion in 48 h at 45 $degree$ c) by the cellulase complex of trichoderma reesei c30 cultured in an 85(w/v) pelf - mineral salts medium. pelf hydrolysate inhibited binding of cellulase enzymes to fresh pelf; the binding of endoglucanase and exoglucanase components was inhibited an average of 27 and 46 respectively by an hydrolysate concentration of reducing sugars equivalent to 6 glucose. this inhibition must be considered in the development of any enzyme recycling system in which cellulases are recovered from the product stream by adsorption on fresh lignocellulosic material.
