the added OMWs indicating that the presence of the inhibitingcompounds of that effluent (e.g. the phenolic compounds) into themolasses-based media negatively affected the metabolism of thestrain. As far as non-aseptic batch bioreactor cultures with con-stant OMW and increasing addition of molasses were concerned,the addition of molasses into the medium reduced biomass pro-duction. S. cerevisiae strain MAK-1 did not grow sufficiently at thetrial with TS0∼ 200 g L−1.
