Growth kinetic and product formation in the selected conditions O2, C2 and AL. Cells grown in RRNCO medium with fructose 13.3 mM were inoculated at an initial OD₆₆₀ of 0.05 and incubated at 30 ºC in constant agitation (200 rpm). Total protein (blue), turbidity (black full circles), PM production (red), fructose (dark blue, empty squares) and polymer amount (green), were measured along the experiment in O2 (A), C2 (B) and AL (C) conditions. Secreted succinate (light blue), propionate (green), acetate (red) and formate (dark blue) were quantified in the culture medium (D, E, F for O2, C2 and AL resp.). Representative curves of three independent experiments are expressed as mean ± SD
