Abstract

Vacuum ethanol removal effect on the fermentative performance of Kluyveromyces marxianus was assessed. Yeast was cultured in bench bioreactor at initial glucose concentration of 90 g L−1 in two sequential batches of 36 h, with a vacuum ethanol removal step and glucose feed before the second batch. Ethanol concentration after the first batch was 34.13 g L−1 (YP/S 0.38 g g−1; QP 0.94 g L−1.h−1), and 40.90 g L−1 (YP/S 0.18 g g−1; QP 0.43 g L−1.h−1) after the second batch. Ethanol production in a control assay without vacuum extraction only happened in the first batch (36.37 g L−1; YP/S 0.4 g g−1; QP 1.01 g.L−1h−1). The phenomenological modeling showed product inhibition and the importance of product removal to process improvement, although the yeast had needed an adaptation period to recover its fermentative metabolism after the stress caused by vacuum.
