dc.description.abstract Wastes from the agro-industrial sector, due to their toxic effects with regard to plants and living organisms, cannot be dumped in the soil. However, they can serve as renewable source of value-added products, following the specific digestive treatment. This research was focused on studies of vinasse fermentation processes in the presence of bioactive substances introduced directly into the digested biomass. The results obtained testify that the substances of natural origin used as additives, demonstrate the pronounced effects on alcoholic fermentation of vinasse under the mesophilic conditions. The comparative assessment of different additives action in the studied processes have demonstrated that the dihydroxyfumaric acid caused the emission of 266 cm3 CO2 in 76 hours, aescinum – 251 cm3 in 55 hours, tomatin – 233 cm3 during 78 hours, sclareol – 232 cm3 during 55 hours, vanillin – 229 cm3 during 69 hours, whereas catechin – 180 cm3 during 61 hours of fermentation, until the fermentation process was completed. Thus, the study of the effects of bioactive substances with possible antioxidant properties on biomass from winemaking sector with identification of these processes mechanisms can be a perspective direction, suggesting the new ways of wastes valorisation. en_US
dc.description.abstract Deșeurile din sectorul agroindustrial, datorită efectelor toxice asupra plantelor și organismelor vii, nu pot fi aruncate în sol, dar pot servi drept sursă regenerabilă de produse cu valoare adăugată. Prezenta cercetare s-a axat pe studiul procesului de fermentare a vinasei în prezența substanțelor bioactive, introduse în biomasa digerată. Rezultatele obţinute mărturisesc că substanţele de origine naturală utilizate ca aditivi demonstrează efectele pronunţate asupra fermentaţiei alcoolice a vinasei în condiţii mezofile. Evaluarea comparativă a acțiunii aditivilor a demonstrat că acidul dihidroxifumaric a determinat emisia de 266 cm3 CO2 în 76 ore, aescinum – 251 cm3 în 55 ore, tomatin – 233 cm3 în 78 ore, sclareol –232 cm3 în 55 ore, vanilină – 229 cm3 timp de 69 de ore, în timp ce catechina – 180 cm3 pe parcursul a 61 de ore de fermentație, până la finalizarea procesului de fermentație. Astfel, studiul efectelor substanțelor bioactive cu posibile proprietăți antioxidante asupra biomasei din sectorul vitivinicol cu identificarea mecanismelor acestor procese poate fi o direcție de perspectivă, sugerând noi modalități de valorificare a deșeurilor. en_US
