Product Overview

General methods in yeast genetics specify using yeast extract-peptone-glucose (YPD) medium for cultivating Saccharomyces cerevisiae and other yeasts. Yeast grow well on a minimal medium containing only glucose and salts. The addition of protein and yeast extract allow faster growth.
