METHOD FOR SUSTAINED MICROBIAL PRODUCTION OF HYDROGEN GAS IN A BIOREACTOR

摘要

The present invention provides a method of hydrogen production from hydrogen producing 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 hydrogen producing microorganisms metabolize an organic feed substrate, wherein the organic feed material in preferably maintained between about 3.5 and 6.0 pH while contained within the bioreactor. The organic feed material is further heated prior to entry into the bioreactor to substantially deactivate or kill methanogens.
