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

Membrane separation processes were applied in the fumaric acid — L-malic acid bioconversion. Electrodialysis was found suitable to recover the free malic acid from its salt (malate), formed in the reaction. Moreover the electrodialytic separation method can be on-line connected to the biochemical pr
