Recombinant Protein Production in Microalgae: Emerging Trends.

Area of Science:

• Biotechnology
• Molecular Biology
• Biopharming

Background:

• Microalgae are a promising, cost-effective platform for large-scale recombinant protein production.
• Chlamydomonas reinhardtii is particularly attractive due to its sequenced genomes and available molecular tools.
• Chloroplast genome transformation offers advantages over nuclear transformation for biopharming.

Purpose of the Study:

• To review the potential of microalgae, specifically Chlamydomonas reinhardtii, as a platform for recombinant protein production.
• To highlight the advantages and challenges of algal chloroplast transformation for biopharming.
• To discuss strategies for improving expression levels in algal chloroplasts for commercial viability.

Main Methods:

• Review of existing literature on microalgal genetic transformation and recombinant protein expression.
• Analysis of studies focusing on chloroplast genome manipulation in Chlamydomonas reinhardtii.
• Examination of factors influencing protein expression levels in algal chloroplasts.

Main Results:

• Over 100 recombinant proteins have been successfully expressed in algal chloroplasts.
• Algal chloroplast transformation presents unique advantages for biopharming applications.
• Current expression levels in algal chloroplasts are generally lower than in higher plants.

Conclusions:

• Microalgae hold significant potential for commercial recombinant protein production.
• Further research is needed to optimize expression levels in algal chloroplasts.
• Developing commercially competitive algal chloroplast expression systems is achievable with targeted research.
