| Summary: | Processing and selection of fruits and vegetables generate high quantities of wastes that represent an economic and environmental issue for the agroindustry sector. According to the so-called “biorefinery” approach, this biomass can be exploited for the recovery of value-added molecules. In this study, the residues of industrial processing of tomato (<i>Lycopersicon esculentum</i> variety “Hybrid Rome”), fennel (<i>Foeniculum vulgare</i>), potato (<i>Solanum tuberosum</i>) and carrot (<i>Daucus carota</i>) were used as sole carbon sources to support cheap and sustainable microbial growth as well as the production of secondary metabolites (hydrogen and ethanol) by <i>Thermoanaerobacterium thermostercoris</i> strain BUFF, a thermophilic anaerobic microorganism isolated from buffalo-dung compost. Moreover, the use of hemicellulolytic enzymes of <i>T. thermostercoris</i> was assayed in the bioconversion reaction of the polymer fraction extracted from the rhizome of giant reed (<i>Arundo donax</i>) and of the leaves and stems of cardoon (<i>Cynara cardunculus</i>), dedicated non-food crops employed in energy supply. |
