Process for the utilization of ruminant animal methane emissions

1. A method for oxidizing methane using a source of oxygen and the enteric fermentation methane produced by one or more ruminant animals as a source of carbon and/or energy, comprising:

a. providing one or more ruminant animals contained in an enclosure;

b. providing a first gas comprising enteric fermentation-derived methane gas that has been emitted by and collected directly from said animals;

c. providing a second gas comprising air that has been combined with said first gas in said enclosure, wherein said second gas comprises oxygen and wherein the concentration of said enteric fermentation-derived methane in said combination of first and second gases is between 1.7 ppm and 1000 ppm;

d. providing a culture of at least one methanotrophic microorganism, wherein said microorganism oxidizes methane to methanol, water, and/or carbon dioxide, wherein said microorganism is unable to utilize said first gas as a sole source of methane;

e. providing a third gas comprising methane, wherein the amount of methane in said third gas is sufficient to support the growth of said at least one microorganism when fed to said microorganism;

f. introducing a combination of said first, second and third gases into a culture chamber comprising said at least one methanotrophic microorganism thereby oxidizing a portion of said methane in both said first and third gases to methanol, water, and/or carbon dioxide.

2. The method of claim 1 , wherein an air conveyor is provided to direct, move, and/or convey said second gas, wherein the air conveyor can be used to contact said second gas with said third gas and/or said microorganism.

3. The method of claim 1 , wherein said microorganism utilizes methane monooxygenase to oxidize methane to intracellular methanol and/or carbon dioxide, and subsequently utilizes said intracellular methanol and/or carbon dioxide for cellular metabolism.

4. The method of claim 1 , wherein said second gas comprises air, dust, non-methane organic matter, ammonia, gases, flies, particulate matter, and/or airborne matter fully or partially contained by said enclosure.

5. The method of claim 1 , wherein said second gas is contacted with said microorganism to function as an oxygen source for said microorganism that reduces environmental enteric fermentation methane emissions.

6. The method of claim 1 , wherein the flow rate of said second gas conveyed through said enclosure is reduced to increase the concentration of said methane within said enclosure, or wherein the flow rate of said second gas conveyed by said conveyor through said enclosure is increased to reduce the concentration of said methane within said enclosure.

7. The method of claim 1 , wherein the temperature and flow rate of said air within said enclosure are simultaneously controlled to optimize the health of said ruminant animals within said enclosure and the concentration of said oxygen and/or methane.
