Figure 1. Quantitation of isoprene production under diverse experimental perturbations inB. subtilis.

Figure 1

Flow chart of the perturbation and sampling protocols. Details are provided in Materials and Methods. B, The isoprene concentrations in the headspace were determined by GC-MS. “OX” represents genetic perturbations in which the listed gene was overexpressed. Bars indicate the mean and error bars indicate standard deviation from the mean.
