KAUST researchers are exploring the potential of algae for various high-value applications, including animal feed, crop fertilizers, and waste remediation. Claudio Grunewald directs a project focused on producing high-protein algae for agriculture. Kyle Lauersen brings expertise in algal synthetic biology and metabolic engineering. Why it matters: Investment in algae research and biotechnology could yield significant returns for Saudi Arabia, contributing to sustainable solutions and economic diversification.
KAUST has launched a pilot algae facility as part of the DAB-KSA project, in collaboration with the Ministry of Environment, Water and Agriculture (MEWA). The facility aims to produce high-protein algae for animal feed, particularly for fish and poultry, using outdoor ponds and closed tubes. KAUST is positioning itself as a center for algal research, leveraging the Kingdom's resources like sunlight, saltwater, and CO2. Why it matters: This initiative could significantly reduce Saudi Arabia's reliance on imported animal feed and contribute to food security.
KAUST's algae biotechnology lab, led by Kyle Lauersen, is isolating and characterizing algal species adapted to Saudi Arabia's climate, using 22 bioreactors to simulate different conditions. The team has isolated over 60 strains, building a biobank for Saudi Arabia, and collaborates with a pilot algal facility supported by the Ministry of Environment, Water and Agriculture to produce high-protein algae for aquaculture. They are also determining optimal conditions for algal growth and measuring oil, protein, and carbohydrate production. Why it matters: This research has the potential to advance Saudi Arabia's bioeconomy by leveraging algae for wastewater treatment, animal feed production, and other applications.
KAUST researchers cultivated the extremophile microalga Cyanidioschyzon merolae, which thrives in hot, acidic conditions, using commercial fertilizer at lab and outdoor large-scale culture. This was part of the Development of Algal Biotechnology in the Kingdom of Saudi Arabia (DABKSA) project, a collaboration between MEWA and KAUST. The microalgae consume pollutants and CO2 to produce biomass like proteins and oils, which can be used as sustainable animal feed. Why it matters: This positions Saudi Arabia as a potential leader in algal technologies, strengthens food independence, and contributes to the country's carbon net-zero goal by 2060.
KAUST researchers have developed a green synthetic biology approach using engineered algae to replicate the complex fragrances of agarwood, also known as oudh. They catalogued the chemical diversity of sesquiterpenes (STPs) in 58 agarwood samples and reproduced some of the chemical complexity of agarwood STPs in algae using synthetic biology. The team used the green alga Chlamydomonas reinhardtii to produce nine distinct STP chemical products widely found in agarwood, offering a sustainable alternative to harvesting endangered trees. Why it matters: This research provides a sustainable route for producing sought-after fragrances, reducing pressure on endangered agarwood tree populations and promoting green chemistry in the region.
