The invention involves the anaerobic growth of S. ruminantium on lactic acid or glucose in a fermentation medium, preferably sterilized, which produces salts of propionic acid and other products in order to supply the energy and materials for growth. It comprises an improved process for preparing sodium propionate from sodium lactate, for instance, for conversion to propionic acid, in at least 1% and preferably 2% yield, and up to 2.4%, based on about 48 hours of fermentation of the lactate. Smaller amounts of acetate and succinate are concurrently produced.
