When lignocellulosic materials are hydrolysed using cellulase fromTrichodermareesei, cellobiose accumulates due to a deficiency in β-glucosidase activity of the enzyme complex. Cellobiose decreases the rate and extent of hydrolysis through feedback inhibition of exo β-1,4-glucanase. Cellulase produced through mixed culture ofTrichoderma andAspergillus showed increased β-glucosidase activity and greatly improved hydrolytic potential.
