Cell growth of four acidic-pH-tolerant mutants of 3.5M-1, 3.5M-2, 3.6M-1, and 3.6M-2 and wild-type Z. mobilis ZM4 under different pH conditions of pH 3.5 (a), pH 3.6 (b), pH 4.0 (c), and pH 6.0 (d) in RMG2. OD values at 600 nm were monitored using Bioscreen C instrument. At least two independent experiments were performed with similar results. Values are the mean of one representative experiment with three technical replicates. Error bars represent standard deviations
