RECOVERY OF CELLULASE FROM LIGNACEOUS HYDROLYSIS RESIDUE

The adsorption of cellulase protein on lignaceous hydrolysis residue w as studied over the range of initial cellulase concentrations: 20-200 FPU/g cellulose. The adsorbed protein (mg/g of substrate) was found to depend on the solids concentration as well as the concentration of pr otein in solution. Soluble reaction products did not affect the adsorp tion of cellulase on residue. Over the range of enzyme loadings studie d, the residue did not saturate with protein. Activity could be recove red from the washed residue by mixing with fresh substrate.
