Fig. 4

End product formation of AK17_WT and strains AK17_M3ad and AK17_M6, on media containing 4.5 g/L glucose. Samples were taken at 0 h (inoculation) and after 24 h (end of fermentation). Acetic acid (dark gray), ethanol (black) and lactic acid (light gray). The absence of a bar indicates the product was below the detection limit. Data represent the average of three replicate experiments. Standard deviations are shown as error bars
