BD Difco YPD Agar; 500g Bottle; Dehydrated media culture; pH 6.5 +/- 0.2; Beige powder; For propagation and maintenance of yeasts in molecular biology

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.

  • Peptone acts as a source of carbon, nitrogen, vitamins and minerals
  • Yeast extract supplies B-complex vitamins, which stimulate bacterial growth
  • Dextrose is the carbohydrate source
  • Agar acts as the solidifying agent
  • pH (6.5% solution, 25°C): 6.5 ± 0.2
