Microalgae based production of single-cell protein

Marcel Janssen et al.

Summary: Microalgae have high protein expression levels and can be produced in contained cultivation systems with low water requirements. Although the current production scale is small, techno economic analysis has shown good potential for scale-up and cost reduction. Microalgal protein has a suitable amino acid composition for food and feed requirements, and high quality can be guaranteed through novel biomass pre-treatment steps.

Microalgae-Based PUFAs for Food and Feed: Current Applications, Future Possibilities, and Constraints

Anna Santin et al.

Summary: Microalgae are considered valuable sources of compounds such as PUFAs for human and animal consumption. Culturing microalgae in open ponds is a common method for production, but it is more susceptible to contamination and lacks reproducibility. Genetic engineering techniques have improved, allowing for modified microalgae to accumulate specific compounds. However, these modified strains should be cultured in closed photobioreactors to minimize contamination and achieve higher yields. This review provides information on microalgae-derived commodities, with a focus on PUFAs, and discusses the challenges and possible solutions for large-scale production.
