Genetic Deregulation of Ethanol-Related Genes
Wild-type Escherichia coli strains are unable to use ethanol as a carbon source. However, they do produce ethanol as a fermentation product under certain conditions of anaerobic growth. In the absence of nitrate, at acidic pH, and especially in the presence of high phosphate concentrations, E. coli ferments glucose mainly to lactic acid. However, at alkaline pH and in the absence of phosphate an equimolar mixture of acetate plus ethanol is the major product (11).
