Title:
NOVEL BACTERIUM THAT CONTRIBUTES TO MASS PRODUCTION OF PROPIONIC ACID PRECURSOR SUBSTANCE
Document Type and Number:
WIPO Patent Application WO/2022/265014
Kind Code:
A1
Abstract:
In order to enable an enhanced propionic acid production and a reduced methane production in the rumen of ruminants, a bacterium of genus Prevotella is provided that characteristically has the following property: the proportion of malic acid and lactic acid in the organic acids in a fermentation product is at least 20%.
