A KAUST-led study has revealed a unique microbial ecosystem in the Hatiba Mons hydrothermal vent fields of the Red Sea, first documented in 2023. Using genome-resolved metagenomics, the study reconstructed over 300 microbial genomes from five vent sites. The analysis showed an ecosystem dominated by microbes capable of iron, sulfur, nitrogen, and carbon cycling, unlike most hydrothermal vents that are sulfur- and methane-based. Why it matters: The discovery provides new insights into microbial processes in extreme conditions, ocean resilience, and global carbon cycling, highlighting the interplay between geology and biology in the Red Sea.
KAUST researchers, in collaboration with Spanish scientists, have released the Global Ocean Gene Catalog 1.0, the world's largest open-source catalog of marine microbes. The catalog, created using the KAUST Metagenomic Analysis Platform (KMAP), matches microbial class with gene function, geographic location, and habitat type, including 317 million unique gene clusters. The catalog analyzes 2102 ocean samples taken from different depths and locations around the world. Why it matters: This resource will enable researchers to investigate ocean ecosystems, track pollution impact, and explore biotechnology applications, potentially driving significant advances in fields like antibiotic discovery and plastic degradation.
KAUST Professor Raquel Peixoto will co-lead the first global body under the International Union for Conservation of Nature (IUCN) to safeguard microbial biodiversity. The Microbial Conservation Specialist Group will explore ecological disruption and potential extinction of microbes vital to ecosystems and human health. The group will assess extinction risks, set conservation priorities, and establish criteria for a microorganism Red List. Why it matters: This initiative highlights the growing recognition of the importance of microbial ecosystems and positions KAUST as a leader in integrating microbiology into global biodiversity governance.
KAUST Professor Heribert Hirt has been elected to Academia Europaea for his research on plant-microbe relationships. His work focuses on identifying beneficial microbial genes and finding local microbes to enhance plant resilience, especially in desert environments. Hirt's research has demonstrated the importance of microbes for plant health and the detrimental effects of chemical-reliant agriculture. Why it matters: This recognition highlights KAUST's contributions to understanding plant resilience in extreme environments and the importance of microbiome research for sustainable agriculture in the region.
KAUST researchers in collaboration with NASA discovered 26 new bacterial species thriving in NASA cleanrooms. These species possess genetic traits that suggest they can survive the harsh conditions of space travel. The study analyzed the genetic traits of extremophiles to understand the risk of their transfer in space missions. Why it matters: This research supports Saudi Arabia's space vision and KAUST's role in microbial and space biology, aiding NASA in anticipating microorganisms encountered in space missions.
KAUST researchers are contributing new information about desert and mangrove plants to support Saudi Arabia's Green Initiative. They are creating a soil atlas for Saudi Arabia, studying soil profiles and microbial populations in hyperarid regions. The team has also compiled the world’s largest biobank of desert microbes, sequencing each microbe's genome. Why it matters: This research is crucial for ensuring the success and sustainability of large-scale greening efforts in arid environments like Saudi Arabia.
KAUST's Darwin21 research group, led by Maged Saad and Heribert Hirt, has developed biostimulant products using plant endophyte microbes to enhance crop resilience in arid conditions. Estidamah, the National Research and Development Center for Sustainable Agriculture, validated Darwin21's products, demonstrating increased vegetable yield and quality with reduced water consumption. A cucumber harvest required only two-thirds of the water when the microbes were applied. Why it matters: This validation paves the way for commercial application, contributing to Saudi Vision 2030's goals of water conservation and food security through innovative agri-technologies.
KAUST postdoctoral fellow Daffne López-Sandoval's marine science research was inspired by Jacques Cousteau's ocean exploration documentaries. She joined KAUST in October 2016 after working at the Institute of Marine Sciences in Barcelona, drawn by the university's potential and opportunities for collaboration. At KAUST, her research focuses on developing new tools to measure microalgae productivity in the Red Sea. Why it matters: This research contributes to understanding the role of marine microbes in the Red Sea ecosystem and their impact on global CO2 sequestration.
