PENICILLIUM FUNICULOSUM AS A SOURCE OF β-GLUCANASE FOR THE ESTIMATION OF BARLEY β-GLUCAN

The β-glucanase in commercial |cellulases prepared from Penicillium funiculosum is more stable to heating than is the equivalent enzyme system from Trichoderma reesei. Consequently the heat-labile amyloglucosidase can be destroyed more reliably in Penicillium cellulase, and it follows that this enzyme is to be preferred for use in the enzymic method for measuring β-glucan.
