4. DiscussionS. cerevisiae MAK-1, presented noticeable DCW production innon-aseptic shake-flask and batch bioreactor fermentations, whenvarious quantities of molasses and OMWs were mixed. Moderateremoval of phenolic compounds from the medium (up to ∼28%,w/w) and significant decolorization (up to 60%) were observed.In non-aseptic shake-flask trials (TS0∼ 100 g L−1), the additionof OMWs into molasses-based media not significantly decreasedbiomass production when compared with the control experiment(no OMWs added). The values of total sugars concentration thatremained unconsumed (TSf= 5.1–18.3 g L−1) rose proportionally to
