Fig. 2.

a Specific growth rate and b maximum specific galactose uptake rate of DHK 1–3 strains. One OD₆₀₀ unit corresponds to 0.27 g dry cell weight (DCW)/L [15]. c–e Time-course fermentation profiles of DHK1-3 strains. The left y-offset, right y-axis, and right y-offset represents galactose, cadaverine, and acetate concentrations (g/L), respectively. The left y-axis represents OD₆₀₀. The x-axis represents the culture time (h). The error bars indicate standard deviations of measurements from two independent cultures. Symbols: open rectangle, OD₆₀₀; open circle, galactose; closed upward triangle, cadaverine; closed downward triangle, acetate
