Development of an immobilization method of L-arabinose isomerase for industrial production of tagatose
Of the immobilization methods tested, alginate beads treated with glutaraldehyde gave the most stable and economic method for immobilizing L-arabinose isomerase for the industrial production of tagatose. L-Arabinose isomerase immobilized in a packed-bed reactor produced an average of 30 g tagatose l(-1) day(-1) from 100 g galactose l(-1) for 8 days.
