Yeast Cultivation and Colony Isolation: Rich medium for growing and isolating yeast colonies (e.g., Saccharomyces cerevisiae) while suppressing bacterial contaminants such as Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, and Staphylococcus aureus via 25 µg/mL kanamycin.

Strain Maintenance and Stocking: Routine passaging, streaking, and preservation of yeast strains with reduced risk of bacterial overgrowth.

Colony Purification: Restreaking mixed cultures to obtain pure yeast isolates by suppressing co-occurring bacteria.

Quality Control of Yeast Cultures: Monitoring for bacterial contamination; kanamycin helps ensure plates yield predominantly yeast colonies.

Replica Plating and Phenotypic Screening: Non-selective yeast growth to compare phenotypes or test stress responses without bacterial interference.

CFU Enumeration and Viability Checks: Counting yeast colony-forming units and assessing culture viability on a rich, supportive matrix.

Inoculum Preparation for Liquid Cultures: Picking healthy yeast colonies from robust YPD for starting overnight cultures or experiments.

Teaching and Training Applications: Educational exercises in yeast handling and plating techniques with minimized bacterial contamination risk.
