In this paper, a long-term investigation of the enzyme hydrolysis of pectin, using a free enzyme membrane reactor (FEMR), is presented. Production of crude enzymes (polygalacturonase and pectin lyase), in Aspergillus niger CECT 2088 cultures grown on an agricultural subproduct (apple pomace) as a low cost inducer, was also studied. Observing the retention of induced pectinases by the ultrafiltration...
Optimisation of pectin hydrolysis using pectolytic enzymes produced by Aspergillus niger CECT 2088 was carried out. The effect of enzyme concentration (0.018–0.072%, w/v), substrate concentration (0.004–0.896%, w/v), pH (4.49–5.91), temperature (32.2–67.8°C) and reaction time (18.2–71.8min) on the enzymatic process was studied. The experiments were arranged according to a central composite statistical...
