Following our previous works, where the production of volatile bio-esters by a commercial wine yeast strain (Vitilevure MT) was studied in submerged fermentation (SmF) using OP complemented with a nutritive medium containing glucose, yeast extract and salts [8] or OP hydrolysate [7], in this work the potential of such a waste as a substrate for flavour-active compounds production by SSF using the same microorganism was investigated.
