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 is collaborating with Coastline Company to convert Red Sea seaweed, specifically Sargassum, into valuable commodities. This initiative addresses the environmental hazard of decomposing seaweed blooms and promotes local employment and a circular economy. KAUST is exploring the use of Sargassum to produce fabric raw materials, alginate for food, biostimulants for agriculture, and fucoidans for therapeutic applications, processing it in a biorefinery manner. Why it matters: This project aligns with Saudi Arabia's sustainability priorities and demonstrates the potential of marine biomass in various industries, including fashion through collaboration with the Saudi Fashion Commission and PYRATEX®.
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 Professor Carlos Duarte gave a TED Talk on seagrass, highlighting their importance as marine ecosystems. His research focuses on Zostera marina, the first marine angiosperm to be fully sequenced. Duarte's team discovered massive clones of Posidonia oceanica in the Spanish Mediterranean, estimated to be 200,000 years old, which play a critical role in carbon sequestration. Why it matters: This research underscores the potential of seagrass in mitigating climate change and protecting coastal regions, emphasizing KAUST's contribution to marine science and environmental sustainability.
KAUST's Professor Carlos Duarte contributed to sequencing the genome of Zostera marina (eelgrass), work published in Nature. The research identifies gene loss and adaptation mechanisms related to the plant's transition from land to marine environments. Eelgrass developed salt resistance, which could inform selective breeding for salt-tolerant food crops. Why it matters: Understanding the eelgrass genome can help in conservation efforts and provide insights into plant adaptation to climate change and marine environments.
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 and MEWA's Aquaculture Development Program (ADP) showcased achievements at the 6th International Saudi Aquaculture Development Workshop. New fish nutrition formulations developed by KAUST Beacon Development (KBD) could save Saudi Arabia $417 million per year in aquaculture production costs by 2030 through improved feed conversion ratios. KBD has also established complete production cycles for Sobaity and Gilthead seabream under Red Sea conditions. Why it matters: These advancements boost Saudi Arabia's food security and promote sustainable aquaculture, reducing reliance on imports and diversifying the economy in line with Vision 2030.
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.
