摘要：
A decreasing feed flowrate was used to optimize the ethanol volumetric productivity and was found to be optimal and equal to 1.8 g ethanol/h . L with a recombinant Escherichia coli with plasmid pLOI297. This productivity is more than double in previous reports. High substrate concentrations favor ethanol production when the microorganisms are in the exponential phase and when they are not inhibited.
