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 (dextrose). It can be used as solid medium by including agar Agar ( or ), or agar-agar, is a jelly-like substance consisting of polysaccharides obtained from the cell walls of some species of red algae, primarily from ogonori (''Gracilaria'') and "tengusa" (''Gelidiaceae''). As found in nature, agar is .... 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 in distilled water. It may be made as a broth, or made into an agar gel by adding 1.5 to 2% agar.
