T. aurantiacus protein production with cellulose and xylan substrates. SDS-PAGE (a), protein concentration (b), CMCase activity (c), and xylanase activity (d) from supernatants of cultures recovered 72 h after shift of glucose-grown cultures to cellulose and xylan substrates. The cultures were pre-grown for 48 h in 2% glucose as carbon source and shifted to cultivation with 1% of each labeled carbon source. Cultivation of the mycelia after shifting to 1% glucose, 5% glucose and no carbon were used as controls. MCC micro crystalline cellulose, SCC Sigmacell cellulose, BC bacterial cellulose, Glc glucose, NC no carbon
