Yeast Culture and Colony Isolation: Routine streaking and single-colony isolation of Saccharomyces cerevisiae and other yeasts on rich medium (1.0% yeast extract, 2.0% peptone, 2.0% dextrose, 2.0% agar).

Yeast Strain Maintenance: Short- and medium-term storage of yeast stocks as patches or slants for subsequent experiments.

Post-Transformation Recovery and Plating: Outgrowth and initial plating of yeast transformants prior to transfer to selective media.

Antibiotic Selection in Yeast: Plating with antibiotics (e.g., G418, hygromycin B, nourseothricin) for selecting engineered yeast carrying resistance markers.

Mating and Patch-Mating Assays: Mixing and growth of haploid strains to promote zygote formation before selection on appropriate media.

Replica Plating and Phenotypic Screening: High-throughput screening of temperature sensitivity, drug sensitivity, and stress-response phenotypes.

Colony PCR Template Preparation: Generating robust yeast colonies suitable for rapid colony PCR workflows.

Viability and CFU Enumeration: Determining yeast cell viability and colony-forming units from cultures or environmental isolates.

Fermentation Strain Isolation: Isolation and propagation of brewing, baking, and bioindustrial yeast strains from mixed samples.

Contamination Monitoring: Detecting microbial contaminants (e.g., Escherichia coli, Bacillus subtilis) in yeast workflows on a rich, nonselective base.
