To add value to the recovered collagen hydrolysate, we evaluated films, cast from this material, for immobilizing degradative enzymes. Organophosphorus hydrolase (OPH) has been shown to be effective in degrading a range of organophosphate esters. Organophosphate compounds, which are among the most toxic substances known, are used as pesticides and nerve gases. A crude extract of OPH from Flavobacterium sp. was immobilized onto collagen hydrolysate films. The collagen films were characterized by differential scanning calorimetry and water swelling behavior. The properties of the collagen hydrolysate films were compared with the films cast from commercially available gelatin. The effect of glutaraldehyde crosslinking the films on enzyme immobilization was studied.
