Technical Article on yeast media. Yeasts are eukaryotic microorganisms whose genomes have been comprehensively studied and some have been sequenced.
The development of genetic engineering and cloning has opened many possibilities of expression and isolation of heterologous proteins for research purposes. Considerable advances in technology have enabled expression and isolation of recombinant proteins in large scale.
Yeast Drop Out Bulletin. The selection of plasmids in yeast is based on the use of auxotrophic mutant strains, which cannot grow without a specific medium component (an amino acid, purine or pyrimidine). Transformation with a plasmid containing the mutated gene enables the transformant to grow on a medium lacking the required component. Although yeast can grow on a synthetic medium without any amino acids, better yield and growth rate can be achieved on richer media.
Yeasts are considered model systems for eukaryotic studies as they exhibit fast growth and have dispersed cells. Yeast cultures can be grown, maintained, and stored in liquid media or on agar plates using techniques similar to those for bacterial cultures.
