应用
酵母氨基酸缺陷型合成培养基添加剂不含尿嘧啶、亮氨酸和色氨酸，可用于筛查：
- 携带pCRISPRyl_URA3sgRNA 质粒的 PO1f 菌株的转化株
- 解脂耶氏酵母 PO1f 菌株的阳性转化株
- CRISPR和 RNA辅助体内定向进化（CRAIDE）突变体
由于在缺乏特定培养基成分（比如氨基酸、嘌呤或嘧啶）的情况下无法生长，营养缺陷型突变菌株的使用很大程度上大决定了酵母质粒的选择。 用含有突变基因的质粒转化，可使转化菌株能够在缺乏所需成分的培养基上生长。 Sigma 公司的′s 酵母营养缺陷型培养基补充剂提供了一种更丰富的培养基，可以提高产量和生长速度，并增加筛选文库或进行基因敲除时转化的成功率。
其他说明
氨基酸和其他营养素的混合物加入到无氨基酸酵母氮源。
制备说明
每升培养基溶解10.4克添加剂。

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.

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
