Ferulic acid esterase catalyses the solubilization of ?-glucans and pentosans from the starchy endosperm cell walls of barley

Abstract

Two separate, highly purified ferulic acid esterases from a fungal and bacterial source are both capable of releasing β-glucan and pentosans from the cell walls of the starchy endosperm of barley. This suggests that ester linkages involving ferulic acid contribute to the integrity of such walls.
