Abstract:

The wine production system produces a big quantity of solid residues whose management and disposal give environmental problems. These wastes are, generally, not intrinsically hazardous but the high content of organic matter and the fact that the production is concentrated in a particular period of the year, pose severe pollution problems. One of the main solid residue generated is pruning material. Several alternatives to the traditional disposals have been investigated, such as composting for stalks [1] or removal of heavy metals from aqueous solutions [2]. However, those residue are rich in carbohydrates and bioactive compounds that can be recovered by suitable processes to produce high-value added products. Grape cane waste can contain up to 15% of their dry weight of non­structural carbohydrates (NSC) [3] in addition to cellulose (about 25%) and xylan (about 7%). Consequently, saccharification of all these polysaccharides is an ambitious target that can be reached with an enzyme-based process. In this paper we described some physicochemical treatment performed on grape pruning material followed by enzymatic hydrolysis with the aim to obtain a complete saccharification of such waste material.
