Vacuum assisted membrane bioreactor for enzymatic hydrolysis of pectin from various agro-wastes

Hydrolysis of pectins extracted from sugar beet, black currant, and red currant were studied by Aspergillus niger polygalacturonase enzyme and strong product inhibition was found. A thermostated membrane bioreactor was applied for the reaction to avoid inhibition and vacuum was used in the permeate side resulting higher product removal rate (flux) and productivity.
