Figure 3From: Increased isobutanol production in Saccharomyces cerevisiae by overexpression of genes in valine metabolismTime profiles of fermentations of ILV2 ILV3 ILV5 BAT2 overexpression (a) and reference strain (b). The ILV2 ILV3 ILV5 BAT2 overexpression strain and the reference strain CEN.PK 113-5D were cultivated under anaerobic batch fermentations in mineral medium with 40 g glucose/l. The concentrations of glucose, biomass, and products are plotted as a function of time. Isobutanol concentrations were measured after glucose depletion in both cases. Fermentations were performed in triplicate, representative cultivations are shown.Back to article page
