Sustainable sparkling base wines obtained from waste matrices of the wine and honey supply chain
The present work was performed to improve the general quality characteristics of sparkling wines produced in Southern Italy (Sicily region) as well as the sustainability of the production process. To this purpose, two novel approaches were applied during experimental winemaking: (i), the use of raceme grapes (formed from the secondary shoots) of Grillo cultivar to improve the chemical characteristics of sparkling base wine; (ii), the technological selection of potential fructophilic Saccharomyces cerevisiae strains isolated from honey by-product to improve the alcoholic fermentations and the organoleptic features of bottled wines. The racemes are typical of Grillo cugrapes and mature 20 day…
Microbiological characteristics of compost produced from dairy and wine by-products
Wine and dairy chains rapresent of the agri-foof leading sectors in Sicily. Composting residues from these two chains would contribute to increase the environmental sustainability of the production with additional advantages represented by the reduction the costs recover soil fertility. This work represents the first attempt to combine the green of the vine cultivation as well as wine and dairy by-products. Raw materials provided potential bioactivators identified as Bacillus subtilis, Bacillus velezensis and Kocuria rhizophila which showed cellulolytic activity. The strain were inocultated in the mass to be composted in order to accelerate the process. Four compost trials were performed: (…
