Fermentation performance of encapsulated T18 using undetoxified hemicellulose hydrolysate in repeated batches in mini reactors and in fixed-bed bioreactor with and without medium recirculation (DO0 = 100, 50 gcell/L, 35 °C and pH 5.2). YP/S is gram of ethanol produced per gram of fermentable sugars consumed, QP is ethanol productivity and qp is the specific ethanol productivity
