مستخلص: This study evaluated simultaneously the raw vinasse degradation, an effluent from the sugar-alcohol industry, the laccase production by Pleurotus sajor-caju and its purification using aqueous two-phase systems (ATPS). To improve laccase production, different concentrations of inducers (ethanol and CuSO 4 ) were added. The higher laccase production promoted an increase of 4-fold using 0.4 mM of CuSO 4 as inducer, with maximum enzymatic activity of 539.3 U/L on the 3 rd day of fermentation. The final treated vinasse had a decolorization of 92% and turbidity removal of 99% using CuSO 4 . Moreover, the produced laccase was then purified by ATPS in a single purification step, reaching 2.9-fold and recovered ≈ 99,9 %, in the top phase (PEG-rich phase) using 12 wt% of PEG 1500 + 20 wt% of citrate buffer + enzyme broth + water, at 25 °C. Thus, an integrated process of vinasse degradation, laccase production and purification with potential industrial application was proposed.
