Copper-repressed Trsho1 caused severe defect on cellulase production. Extracellular hydrolytic activities of pNPC (a), pNPG (b), FPA (c), and total protein concentration (d) of the parent strain and the P tcu1 -sho1 strain were determined. All strains were cultured on 1% (w/v) Avicel supplied with or without CuSO4
