Abstract
Compositions of ferulate esterase producing bacterial strains or functional mutants thereof and methods of using ferulate esterase producing bacterial strains as silage inoculants for the enhancement of biogas production are disclosed. Ferulate esterase producing bacterial strains of Lactobacillus, including Lactobacillus buchneri, or functional mutants thereof are used as silage inoculants to improve the degradation of plant biomass for enhanced production of biogas.
Claims8
A method for enhancing biogas production from plant silage, said method comprising:
- adding an effective amount of a ferulate esterase containing composition to said silage, wherein said ferulate esterase is derived from a biologically pure culture of a ferulate esterase producing Lactobacillus buchneri strain, wherein said Lactobacillus buchneri strain is selected from the group consisting of Lactobacillus buchneri, strain LN4017, deposited as Patent Deposit No. PTA-6138;
- Lactobacillus buchneri, strain LN4888, deposited as Patent Deposit NRRL B-30866;
- and mixtures thereof;
- adding said silage to a biogas generator;
- and
- producing an increased amount of biogas in comparison to silage not treated with a ferulate esterase containing composition.
