Overview
This medium is described by Lewis (1960). The addition of phosphoric acid allows less propionic acid to be used without reducing its fungicidal effects. It is the food used at Caltech since 1955. At Caltech the food is always seeded after cooling with a yeast strain called 'Y-2 Original', which tolerates propionic acid. See Lewis (1960) for details of this yeast and its use.
