Growth and ethanol fermentation of Z. mobilis mutants tolerant to acetic acid. a RM50; b RM50 + 5.0 g/L acetic acid; c RM50 + 7.0 g/L acetic acid, and d RM50 + 8.0 g/L acetic acid. Growth is indicated by OD600 value; glucose indicates the concentration of the sugar remained in cultures; EtOH indicates the concentration of ethanol produced
