quantities were achieved, it was further desirable to study the effecton increasing addition of molasses upon the growth of the strainunder no aeration conditions in media with OMWs added to a ratioof 20% (v/v), therefore, molasses were added in increasing amountsin OMW-based media resulting in increasing TS0concentrationsas follows (in g L−1): ∼100, ∼135, ∼150 and ∼200 g L−1. Incre-ment of molasses quantity into the medium negatively affectedbiomass production in terms of absolute values (g L−1) and sugarassimilation by the strain (Table 2), suggesting that high pheno-lic (principally melanoidin) content affected negatively the strainmetabolism. S. cerevisiae did not grow sufficiently at the trial withTS0∼ 200 g L−1.
