Engineering Approaches for Sustainable Protein Production in Microalgae: A Comprehensive Review.
2025Objective: Develop sustainable microalgae-based protein production platforms by combining upstream cultivation optimization, strain modification, downstream processing, extracted-protein recovery, and biorefinery integration.
Why it works: The review frames protein production as a multi-stage engineering problem in which upstream cultivation and strain modification increase biomass and protein accumulation, while downstream processing and recovery determine product quality and application range, and biorefinery integration improves economic viability.

Stages
- 1.Upstream cultivation optimization(functional_characterization)
The review states that mixotrophic cultivation is often preferred to maximize protein production and that light quality, carbon sources, and nitrogen availability direct metabolic fluxes toward protein biosynthesis.
Selection: Optimize cultivation mode and environmental inputs to maximize protein production and biomass yield.
- 2.Strain modification(functional_characterization)
The abstract identifies CRISPR/Cas9 as promising but still challenging and limited for enhancing microalgal protein production, while random mutagenesis is described as proven effective across multiple strains.
Selection: Apply genetic or mutational approaches to improve strains for protein accumulation.
- 3.Whole-cell downstream processing(secondary_characterization)
The abstract emphasizes drying, extrusion forming, and fermentation as downstream engineering approaches for improving whole-cell product properties.
Selection: Use downstream processing methods to improve nutritional and functional properties of whole-cell microalgal protein products for food and feed.
- 4.Extracted-protein recovery and quality shaping(secondary_characterization)
The abstract states that extracted proteins broaden potential applications and that their quality is significantly affected by cell disruption/extraction, purification, and hydrolysis methods.
Selection: Choose extraction, purification, and hydrolysis methods that support desired quality in extracted microalgal proteins.
- 5.Protein-first biorefinery integration(decision_gate)
The abstract states that novel biorefinery strategies enhance economic viability by integrating value-added biomass utilization within a protein-first recovery scheme.
Selection: Integrate value-added biomass utilization around a protein-first recovery scheme to improve economic viability.
