Application

Yeast Synthetic Drop-out Medium Supplements, without uracil, leucine, and tryptophan has been used for screening:

  • the transformants of the PO1f strains which carried the pCRISPRyl_URA3sgRNA plasmids[1]
  • Yarrowia lipolytica PO1f strain positive transformants[2]
  • CRISPR- and RNA-assisted in vivo directed evolution (CRAIDE) mutants[3]
The selection of plasmids in yeast is based on the use of auxotrophic mutant strains that cannot grow without a specific media 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. Sigma′s Yeast Synthetic Drop-Out Media Supplements create a richer medium for better yield and growth rate, and increase the probability of successful transformations when screening libraries or performing gene knock-outs.

Other Notes

Mixtures of amino acids and other nutrients to be added to Yeast Nitrogen Base Without Amino Acids.

Orotic acid (OA) is an intermediate of the pyrimidine biosynthesis with high industrial relevance due to its use as precursor for production of biochemical pyrimidines or its use as carrier molecule in drug formulations. It can be produced by fermentation

Directed evolution is a powerful approach to obtain genetically-encoded sought-for traits. Compared to the prolonged adaptation regimes to mutations occurring under natural selection, directed evolution unlocks rapid screening and selection of mutants with improved traits from vast mutated sequence spaces.
Paul Swietalski et al.
Microbial cell factories, 19(1), 100-100 (2020-05-13)
The secretory production of recombinant proteins in yeast simplifies isolation and purification but also faces possible complications due to the complexity of the secretory pathway. Therefore, correct folding, maturation and intracellular transport of the recombinant proteins are important processing steps
