[0129] Preparation of Microbial-Based Products

[0130] The present invention provides microbial-based products that reduce methane emissions from livestock production. A microorganism-based product of the invention is simply a fermentation medium comprising the microorganisms and / or microbial metabolites and / or any residual nutrients produced by the microorganisms. Fermented products are used directly without extraction or purification. Extraction and purification can be readily achieved, if desired, using standard extraction and / or purification methods or techniques described in the literature.

[0131] In one example, the yeast fermentation product designated "Star 3+" can be obtained by culturing the killing yeast, Wickhamiana anomalies, using a modified form of solid state fermentation. Cultures can be grown on surfaces with sufficient surface area for yeast to attach to and multiply on, such as rice, soybeans, chickpeas, pasta, oatmeal, or beans. For example, whole ye...

Embodiment 1

[0187] Example 1 - Production of Sophorolipids

[0188] Fermentation temperatures are typically between about 22-28°C, depending on the microorganisms and / or microbial growth by-products being cultured. For Candida globosa, a temperature of about 25°C is optimal.

[0189] The pH should be from about 2.0 to about 7.0, preferably from about 3.0 to about 6.5, depending on the microorganisms and / or microbial growth by-products being cultured. Additionally, to reduce the possibility of contamination, the cultivation process can be initiated at a first pH range and then adjusted to a second pH range above or below the first pH range.

[0190] Under these culture conditions, industrially useful production of biomass, biosurfactants and other metabolites is achieved after a minimum of 24 hours of fermentation. After the fermentation is complete, the growth by-products and / or remaining culture can be harvested from the reactor and used for a variety of industrial purposes.

Abstract

The subject invention provides compositions and methods for reducing atmospheric methane and / or nitrous oxide emissions using livestock feed additives and / or supplements. In preferred embodiments, a composition comprising a beneficial microorganism and / or a growth by-product thereof is contacted with animal feed and / or drinking water prior to the animal ingesting it. The composition is capable of, for example, controlling methanogenic microorganisms within the animal's digestive system, and thus, reducing the amount of enteric methane emissions produced from the animal and from the animal's waste.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 743,167, filed October 9, 2018, and U.S. Provisional Patent Application No. 62 / 885,929, filed August 13, 2019, which Both are incorporated herein by reference in their entirety. Background technique [0003] Gases that store heat in the atmosphere are called "greenhouse gases" or "GHGs" and include carbon dioxide, methane, nitrous oxide, and fluorinated gases (EPA report 2016 p. 6). [0004] Carbon dioxide (CO2) enters the atmosphere through the burning of fossil fuels (coal, natural gas and oil), solid waste, trees and wood products, and certain chemical reactions (eg, cement manufacturing). Plants remove carbon dioxide from the atmosphere by, for example, uptake as part of the biological carbon cycle. [0005] Nitrous oxide (N2O) is emitted from industrial activities and during the combustion of fossil fuels and solid waste. In agricultur...
