YEPD
YEPD or yeast extract peptone dextrose, also often abbreviated as YPD, is a complete medium for yeast growth. It contains yeast extract, peptone, double-distilled water, and glucose or dextrose. It can be used as solid medium by including agar. The yeast extract will typically contain all the amino acids necessary for growth. By being a complete medium, YEPD cannot be used as a selection medium to test for auxotrophs. Instead, YEPD is used as a growth medium to grow yeast cultures.
YEPD typically contains 1% yeast extract, 2% peptone, and 2% glucose/dextrose in distilled water. It may be made as a broth, or made into an agar gel by adding 1.5 to 2% of agar to hot broth and allowing the mixture to cool and solidify.
