A solid medium for the propagation of yeast. synonym: YEPD agar

YPD broth is used for the propagation and maintenance of yeasts.

General methods in yeast genetics specify using yeast extract-peptone-dextrose (YPD) medium for cultivating Saccharomyces cerevisiae and other yeasts. Yeasts grow well on a minimal medium containing only dextrose and salts. The addition of protein and yeast cell extract hydrolysates allows faster growth so that during exponential or log-phase growth, the cells divide every 90 minutes.

● Yeast extract supplies B-complex vitamins, which stimulate bacterial growth
● Peptone acts as a source of carbon, nitrogen, vitamins and minerals
● Glucose is the carbohydrate source
