KAUST researchers have developed a new synthetic biology process using metabolically engineered algae to produce fragrant sesquiterpenoids, the core compounds in agarwood and other perfumes. The process, developed by the Lauersen and Szekely groups, achieved yields 25 times higher than previous methods and allows for the synthesis of 103 types of fragrant sesquiterpenoids. It also incorporates an energy-efficient nanofiltration step and operates at room temperature with minimal waste. Why it matters: This sustainable bioprocess offers a green alternative to environmentally damaging harvesting of natural resources for the $44 billion fragrance industry, with potential applications in drug development.
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.
KAUST researchers collaborated to identify molecular pathways for plant biofortification of vitamin A. A KAUST group demonstrated high pressure conversion of carbon dioxide into useful products. Another team designed a biosensor using metal oxide transistors to detect glucose in saliva. Why it matters: These projects highlight KAUST's contributions to biotechnology, environmental sustainability, and healthcare through advanced materials and molecular techniques.
KAUST researchers led by Mark Tester are developing new irrigation technology to enable crop production using semi-saline water, aiming to reduce freshwater reliance to 10% in greenhouse systems. The technology is eco-friendly and intends to cut agricultural costs by utilizing seawater, targeting a cost of 10 U.S. cents per cubic meter. A new company named Red Sea Farms is being developed to grow salt-tolerant tomatoes in diluted seawater in a greenhouse cooled with undiluted seawater. Why it matters: This research could significantly reduce pressure on freshwater resources in arid regions and offers a sustainable approach to increase food production using available seawater.
KAUST, the National Livestock and Fisheries Development Program (NLFDP), and the National Research and Development Center for Sustainable Agriculture (Estidama) are collaborating to explore algae-based biostimulants for agriculture. These biostimulants, derived from marine algae, enhance plant growth and nutrient uptake without the negative impacts of chemical fertilizers. KAUST already operates a commercial-scale algae manufacturing plant capable of producing tons of algae per month for biostimulant production. Why it matters: This initiative positions Saudi Arabia as a leader in sustainable food technology by leveraging algae biostimulants to improve soil health and reduce dependence on imported raw materials.
KAUST researchers from the Red Sea Research Center (RSRC) and Computational Bioscience Research Center (CBRC) found macroalgae DNA prevalent in the open ocean, up to 5,000 km from coastal areas. 69% of drifting macroalgae sinks below 1,000 m depth, sequestering carbon in deep ocean waters. The study used metagenomes generated by global ocean expeditions Tara Oceans and Malaspina, analyzed via KAUST's DMAP platform and Shaheen supercomputer. Why it matters: The findings confirm the role of macroalgae in carbon sequestration, highlighting their importance in blue carbon assessments for climate change mitigation and underscoring KAUST's contribution to environmental sustainability research.
KAUST researchers have developed polytriazole membranes for energy-efficient crude oil fractionation, as detailed in a recent Science Magazine paper. Led by Dr. Suzana Nunes and Dr. Stefan Chisca, the team created membranes that can withstand harsh industrial conditions like high temperatures and organic solvents. The membranes offer a low-carbon footprint alternative to traditional separation techniques like distillation. Why it matters: This innovation could significantly reduce energy consumption and promote a circular carbon economy in the petrochemical industry within the GCC region and beyond.
KAUST researchers developed a tandem solar cell with 32.5% conversion efficiency by optimizing the silicon-perovskite connection. Another team combined spectroscopy and reactor technologies to reveal details on catalyst function and reaction mechanisms. A KAUST team also developed a mathematical framework improving data rates by 30% and optimizing terrestrial network speeds. Why it matters: These advances highlight KAUST's contributions to sustainable energy, industrial processes, and network optimization, addressing key challenges in the region and globally.
