Comparison of specific growth rate (μ, liters per hour), volumetric productivity (grams per liter per hour) and product yield on glucose (Y P/S, gram per gram) of the high isobutanol producer (JCL260), high isobutanol-tolerant (SA481), and parental (JCL16) strains cultured at 30°C and JCL260 at 37°C. The μ was calculated during the exponential growth phase. Error bars indicate the difference between replicate cultures
