Yeast, such as Saccharomyces cerevisiae and Pichia pastoris, is another popular host for recombinant protein production. Yeast combines the simplicity of bacterial systems with the ability to perform some post-translational modifications, making it a versatile option.

Applications

• Ideal for producing proteins that need glycosylation, though yeast glycosylation differs from mammalian cells.
• Widely used in vaccine production.
• A common platform for enzymes used in biotechnology and food industries.
