Utilization of sugars and production of extracellular proteins by VTT-BR-C0022 as compared to parental strain VTT-BR-C0020. Consumption of glucose, fructose and sucrose, and secretion of extracellular protein by invertase-expressing strain VTT-BR-C0022 and parental strain VTT-BR-C0020 cultivated on three different carbon sources: a pure glucose + fructose, b pure sucrose and c sugarcane molasses. In all cases the carbon source was used at a concentration of 30 g/l and supplemented with 3 g/l yeast extract as an organic nitrogen source
