Abstract:
An ultrafiltration reactor was developed for the continuous saccharification of liquefied corn starch using glucoamylase. At an enzyme concentration of 1 g/L and a substrate concentration of 300 g/L, maltose and maltotriose were still detected in the reactor permeate after 4 hr of operation. At higher enzyme concentrations (6 and 12 g/L), the reactor achieved steady-state operation within 1-3 hr at all substrate concentrations studied. At an enzyme concentration of 12 g/L, residence time did not affect the final conversion of liquified starch to glucose. The ultrafiltration reactor produced glucose syrups at residence times of 2-3 hr and substrate concentrations up to 30% w/v.
