Figure 4

Effects of gene overexpression on isobutanol yield in various media under aerobic conditions. The isobutanol yields (mg per g glucose) of the reference strain (CEN.PK 113-5D) and the ILV2 ILV3 ILV5 overexpression strains are presented with columns with different colours, and the values are shown on the top of each column. All cultivations were carried out aerobically in shake flasks in either mineral medium with 40 g glucose/l or yeast extract/peptone/dextrose (YPD) complex medium with 17 g glucose/l.
