Increased Content of Free Phenolic Compounds and Antioxidant Activity of Grape Pomace Cultivated with Three Different β-glucosidase Fungi Producers

In this research, we tried to recover the antioxidant activities of grape pomace by means of using solid-state cultivation (SSC) of Aspergillus niger BLAn1, Phanerochaete chrysosporium BLPc1, and Penicillium sp. BLPen1, three GRAS strains of fungi. We measured the enzymatic activities of β-glucosidase, responsible for liberating the aglycone forms of the phenolic compounds, as well as their total content. The highest β-glucosidase activities...
