REUSE OF WINE INDUSTRY WASTES OF ARGENTINA USING PHENOLIC COMPOUNDS EXTRACTED FOR CANKER CONTROLRODRIGUEZ-VAQUERO MJ*, SOSA-MARMOL MS and SAGUIR, FMFaculty of Biochemistry, Chemistry and Pharmacy, National University of Tucuman ? CONICET. Ayacucho 491, (+54)381-4247752 ext. 7067, 4000, Tucuman, Argentina.Argentina is the first producer of lemon and Tucuman is responsible of 89.8% of country lemon production. One problem in this activity is citrus canker caused by Xanthomonas citri subsp. citri. The vinification process generates a great amount of residues. The possibility of reutilization of these wastes is a new alternative for the final disposal of the waste. The aim of this work was the recovery of phenolic compounds (PC) present in winery wastes, the development of techniques for PC extraction, the investigation of the effect of PC extracted from winery wastes (PEWW) on the viability of X. citri sp citri in vitro and in vivo assays and the influence on biofilm formation by this bacterium. Results showed that both PEWW were effective to inhibit the growth of X. citri, and a bactericide effect was shown with the high concentration tested. In vivo and in vitro assays demonstrated that PEWW from grape skin and grape seeds possess antibacterial activity against X. citri. The biofilm formation was reduced in presence of all samples. Ours results demonstrated that the use of winery waste, as source of PC is a promising environmentally friendlier method to control the presence of X. citri in citrus.
