Abstract

The present invention provides a method of hydrogen production from microorganisms, wherein a bioreactor provides an environment conducive to the production of hydrogen from hydrogen producing microorganisms and restrictive to the production of methane from methanogens. The method further includes an equalization tank that provides improved control of flow rates, particularly when combining the hydrogen production system with an industrial process such that organic feed material obtained from the industrial process is utilized in the hydrogen production system. The environment in the bioreactor is preferably maintained between about 3.5 and 6.0 pH.
