Yeast Cultivation and Propagation: Rich, carbon-source–free medium for routine growth, starter cultures, and colony expansion; add dextrose to make YPD.

Preparation of YPD Broth and Plates: Mix 1:1 with 4% dextrose to obtain 1X YPD (2% glucose); add agar for plate pouring.

Transformation Recovery/Outgrowth: Supports rapid, non-selective recovery of yeast after chemical or electroporation-based transformation.

Protein Expression in Yeast: Base medium for expression workflows using YP + galactose/raffinose (e.g., GAL-promoter–driven expression).

Fermentation and Growth Kinetics: Enables carbon-source testing and growth curves by supplementing glucose, galactose, glycerol, or ethanol.

Biomass Production for Downstream Analyses: Generates high-density yeast cultures for DNA/RNA/protein extraction.

Non-Selective Expansion Prior to Selection: Short outgrowth before transfer to selective media for genetic screens or phenotypic assays.

Media Optimization Studies: Benchmark rich base (2.0% yeast extract, 4.0% tryptone) for supplement and additive testing.
