YPD

Summary
YPD Medium (aka YEPD). Standard growth medium for yeast.

Ingredients

 * 10 g yeast extract
 * 20 g peptone
 * If making plates add 20 g agar
 * 2% (w/v) glucose (20 g)

Protocol

 * 1) Mix dry ingredients (except glucose) and add distilled water up to 950 mL
 * 2) Pour into 2 L flask (or greater)
 * 3) Autoclave (liquid cycle)
 * 4) * 250&deg; F, 22 psi, 30 minutes

Notes: We do not pH medium when we make it on the fly. However, if it is really important, pH the medium to 7.0 with 5M NaOH (~200µL). We usually obtain this from the kitchen.
