Growth, 5-KF formation, and fructose consumption of the indicated G. oxydans strains in shake flasks. Depicted is a the cell density as OD600, b the 5-KF concentration, and c the fructose concentration determined by HPLC (method A). The strains were cultivated in 100 mL complex medium with 18 g/L fructose in 500 mL baffled shake flasks at 30 °C, 130 rpm, a shaking diameter of 50 mm, and 85% humidity. Shown are mean values of biological duplicates
