2,3-BD production by C. sakazakii OX-25 at different temperatures in a xylose medium. Cells were cultivated in YP medium supplemented with 20 g/l xylose at 37 ˚C (filled circles), 40 ˚C (filled squares), 42 ˚C (filled triangles) and 45˚C (filled diamonds) under a shaking condition at 100 rpm. a Turbidity (OD₆₀₀) and the concentrations of b glucose, c 2,3-BD and d acetoin in the culture medium were determined as described in Materials and methods. Error bars indicate standard deviation of three independent experiments
