Yeast cells for recombinant protein production

Traditional methods for acquiring pharmaceutical raw materials, such as plant extraction or relying on natural organisms, face challenges like long growth cycles and limited yields. Microbial recombinant protein synthesis technology, particularly using yeast as a production host, offers a promising alternative for biopharmaceutical production. Through intricate cellular engineering designs, yeast cell factories are advancing toward large-scale industrial applications.

Cellular Engineering:

Promoter Engineering: Optimizing yeast promoters like AOX1 in Pichia pastoris for self-regulation and using CRISPR/Cas9 for precise gene manipulation.

Secretion Pathway Optimization: Enhancing yeast secretion pathways to improve recombinant protein yields and quality.

Glycosylation Engineering: Modifying yeast glycosylation patterns to match human glycosylation, reducing immunogenicity, and expanding yeast applications.

Fermentation and Scale-Up Strategies:

Growth and Production Kinetics: Understanding the impact of carbon sources on yeast growth and protein production kinetics.

Strain Screening and Culture Optimization: Efficiently screening recombinant strains and optimizing culture conditions to significantly increase protein yields.

Development of Bioprocesses in Non-Traditional Yeasts:

Utilizing yeasts like Kluyveromyces lactis, Hansenula polymorpha, and Yarrowia lipolytica for specific biopharmaceutical production through tailored fermentation processes.

In conclusion, while customized yeast cell factories have made significant strides in biopharmaceuticals, continuous exploration and refinement are necessary. Future developments in gene expression regulation, glycosylation engineering, and fermentation processes will undoubtedly enhance their role in creating new possibilities for human health.
