  • COMPOSITIONS AND METHODS COMPRISING A COMBINATION SILAGE INOCULANT
    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.

  • Cloning and Sequencing of the Ferulate Esterase Gene From Lactobacillus Buchneri LN4017
    Publication number: 20110154533
    Abstract: Embodiments of the present invention include polypeptides having ferulate esterase activity and the nucleic acid sequences that encode them. Methods of the embodiments utilize these ferulate esterase polypeptides and nucleic acid sequences to enhance the digestibility of plant cell walls and the accessibility of carbohydrates in plants. The invention provides for transgenic plants and bacteria transformed with expression vectors containing a DNA sequence encoding ferulate esterase from Lactobacillus buchneri. Methods of using same to enhance plant fiber digestion in animals, are disclosed. Uses of this invention include, but are not limited to, forage and silage with improved digestibility for livestock, and enhanced biomass conversion.
