ABSTRACT:
Storage stable, lyophilized, acid producing bacteria, such as lactic acid bacteria, are prepared by lyophilizing the bacteria in the presence of at least 5% by weight of the bacteria of a basic organic or inorganic buffering agent, preferably an alkali metal salt of glycerophosphate, to provide lyophilized bacteria containing less than 5% by weight water, and sealing the lyophilized bacteria in a container while in a vacuum or surrounded by a gaseous atmosphere substantially free of oxygen, preferably argon which is essentially free of oxygen.
