PURPOSE:To enable the cleaning of waste water, the reutilization of the produced precipitate of bacterial cells, and the production of fuel gas economically on an industrial scale, by transferring a liquid containing large amount of proliferated aerobic bacterial cells quickly to an anaerobic state to effect the generation of hydrogen gas. CONSTITUTION:For example, the waste water of a starch-processing plant is aerated to proliferate a large amount of aerobic bacterial cells (e.g. Escherichia coli) and is transferred quickly to an anaerobic state to effect the generation of a large volume of hydrogen gas preferably in the presence of a phytosynthetic bacterial (e.g. Rhodopseudomonas capsulata). The objective fuel gas is produced by this process.
