<p>A method for producing isopropyl alcohol, comprising: culturing isopropyl-alcohol-producing Escherichia coli, which has been undergone introduction or modification by genetic recombination and retains an isopropyl-alcohol-producing ability, under bacterium-proliferating conditions in which the Escherichia coli can be proliferated stably in an isopropyl alcohol production phase while keeping the number of cells of the Escherichia coli in a culture vessel at a certain level and while continuously supplying a substrate solution containing a plant-derived raw material to the culture vessel and continuously removing a product-containing culture liquid from the culture vessel; bringing the isopropyl-alcohol-producing Escherichia coli into contact with the plant-derived raw material in the culture vessel to produce isopropyl alcohol; and collecting isopropyl alcohol that is produced by the isopropyl-alcohol-producing Escherichia coli from the product-containing culture liquid removed from the culture vessel.</p> |
