15. BIODEGRADATION OF ACACIA AND CHESTNUT TANNINS BY NATIVE ISOLATES OF THE GENUS Penicillium AND Aspergillus
Abstract In the present work, the potential of native isolates of fungi strains to biodegrade vegetable tannins used in the tanning industry was evaluated. Penicillium citrinum showed to be more efficient for consumption of acacia tannin, reaching 94.85%. Aspergillus chevalieri needs a greater adaptation phase (48 h) in both acacia and chestnut medium, evide

20. Evaluation of the potential astringency of the skins and seeds of different grape varieties based on polyphenol/protein binding
Abstract The potential astringency of eight grape cultivars was evaluated based on polyphenol/protein binding. The parameters such as weights, sizes, total phenols, flavanols and tannins of different grape tissues were determined, and the polyphenol/protein binding was analyzed by SDS-PAGE and spectroscopy. The Cabernet Sauvignon had the highest skin proport
