Celluclast and Cellic ® CTec2: Saccharification/fermentation of wheat straw, solid–liquid partition and potential of enzyme recycling by alkaline washing

•Cellic is more efficient catalyst than Celluclast, but is more sensitive to deactivation.•Efficient hydrolysis leads to improved recovery of soluble cellulases.•Alkaline treatment is an efficient method to remove enzymes lignin-adsorbed.•Enzyme recycling strategies must be customized for each enzyme formulation.
