Yeast Strain Maintenance: Defined minimal agar for routine cultivation of Saccharomyces and Candida using 2.0% glucose and 0.5% ammonium sulfate.

Auxotrophic Selection: Selection of transformants (e.g., URA3, LEU2, HIS3, TRP1 markers) when used with appropriate dropout supplements.

Plasmid Maintenance: Stable selection and propagation of plasmid-bearing yeast under defined nutritional conditions.

Colony Isolation and Enumeration: Streaking, single-colony isolation, and CFU counts on a standardized minimal medium.

Yeast Two-Hybrid Screening: Growth and reporter selection on SD-based selective plates (e.g., -Leu/-Trp/-His) prepared with this YNB agar base.

Metabolic and Carbon Utilization Studies: Baseline growth on 2.0% glucose for comparative metabolic assays and nutrient limitation studies.

Phenotypic Screening: Assessment of growth under stressors (e.g., pH, osmotic, drug exposure) in a chemically defined matrix.

Quality Control of Yeast Cultures: Purity checks and verification of strain identity on minimal, reproducible agar.
