METHOD OF ORGANIC ACID FERMENTATION BY RUMEN FLUID USING CELLULOSE-CONTAINING WASTE MATTER

摘要

[Prpblem] To provide a method for producing acetic acid, propionic acid, butyric acid, or another high-quality raw material designed for methane fermentation and obtained by converting waste paper and other forms of cellulose-based biomass to organic acid. This method serves as a method for the effective use of cellulose-containing waste matter, which is a high-quality fermentation resource. [Solution] A method for producing organic acid to serve as a raw material for methane fermentation, the method comprising a step for reacting rumen fluid collected from a ruminant animal with cellulose-containing waste matter. Also, a method for performing methane fermentation to produce methane using, as a raw material, either the organic acid produced by the method for producing organic acid, or processed rumen fluid product containing the organic acid.
