The impact of isobutanol concentration on the growth of Z. mobilis. The growth of Z. mobilis ZM4 in rich medium (RM) with isobutanol (Iso) supplementation at concentrations of 0, 4, 8, 12, 16, or 20Â g/L (a), and the corresponding growth rates with 0, 4, 8, or 12Â g/L isobutanol supplementation (b). At least two independent experiments have been carried out with similar results. Values are the mean of one representative experiment with three or more technical replicates. Error bars represent standard deviations
