Summary
Tests made to study the relation between filter paper activity and actual saccharifying ability of Trichoderma cellulases show that 30 IU/g of cellulose were sufficient to achieve over 80% hydrolysis of a 25 g/L cellulose suspension in 24 h. With the same enzyme/substrate ratio, but double the concentration of substrate, about 60% hydrolysis was achieved. End- product inhibition is one factor which seriously limits the degree of hydrolysis and therefore the concentration of sugars achievable by enzymatic hydrolysis at high levels of substrate concentration or enzyme/substrate ratio.
