  • Publication number: 20140186929
    Abstract: Compositions and methods for the production of biogas from forage are provided. Compositions comprise a combination microbial inoculant, silage produced from forage inoculated with the combination microbial inoculant, and biogas produced from the silage. Various methods are provided for increasing biogas production and decreasing dry matter loss by inoculating forage with a combination inoculant. In certain embodiments, inoculating forage with specific combinations of bacterial strains results in a synergistic decrease in dry matter loss and a synergistic increase in biogas production. In other embodiments, inoculating a biomass composition comprising silage and sludge with specific combinations of bacterial strains results in a synergistic increase in biogas production.

  • Publication number: 20090028992
    Abstract: A method for treating silage to enhance aerobic stability by inhibiting growth of microorganisms selected from yeasts, molds and spore-forming bacteria is disclosed. The method comprises treating silage or feed with a composition comprising Lactobacillus buchneri, LN1286, or the antimicrobial components produced thereby. The strain of Lactobacillus buchneri disclosed in the invention has been purified and isolated and has been found to be nontoxic, safe and able to improve aerobic stability of silage.
