A KAUST Global Ocean Genome workshop convened international scientists to discuss and evaluate the global ocean genome's progress. Participants assessed the representation of microbial communities and their gene pools, explored the functional capacities of the global ocean microbiome, and examined the distribution of key functional genes. KAUST aims to become a repository of global metagenome data, using big-data systems to explore ocean metagenome knowledge. Why it matters: This initiative highlights KAUST's commitment to advancing microbiome research and fostering international collaboration in marine genomics, positioning the university as a key player in understanding and utilizing ocean biodiversity.
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.
Researchers at KAUST and international collaborators have published a framework in Nature Microbiology for using microbiomes to protect wildlife. The framework outlines a path from laboratory research to large-scale applications of microbiome solutions for threatened ecosystems. It addresses ethical considerations and risk assessment for applying environmental probiotics. Why it matters: This framework provides a science-based guide for responsible research and development of microbiome solutions to combat global biodiversity loss, particularly in sensitive marine ecosystems like coral reefs.
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 researchers studied microplastic distribution in the open ocean during a recent expedition. They found microplastics everywhere but in 100 times lower quantities than expected based on production estimates. The study found larger plastic debris at expected levels, but smaller microplastics were disappearing, suggesting they are either sinking or entering the marine food chain. Why it matters: This research highlights the urgent need to understand the fate of microplastics in marine ecosystems and their potential impact on marine life and human health.
KAUST researchers demonstrated that Beneficial Microorganisms for Corals (BMC) can help corals recover from thermal stress by stimulating immune processes and rebuilding their microbiome. The study, published in Science Advances, showed that probiotic treatments can protect bleached corals from death. The research was conducted at the Federal University of Rio de Janeiro (UFRJ) and the KAUST Red Sea Research Center, with funding from the Great Barrier Reef Foundation and the Tiffany & Co Foundation. Why it matters: This finding offers a promising solution for mitigating the impacts of climate change on coral reefs, which are vital ecosystems facing increasing threats from warming ocean temperatures.
KAUST researchers have discovered that a coral's resilience to rising temperatures is determined by the microorganisms living inside them. The study identifies specific combinations of microeukaryotes and bacteria that enhance heat resistance in corals. This finding provides valuable clues for developing coral probiotics to protect and restore coastal reefs. Why it matters: This breakthrough could lead to effective interventions to combat coral bleaching and preserve vital marine ecosystems in the Red Sea and beyond.
KAUST Professor Raquel Peixoto has been awarded the inaugural Rachel Carson Prize for microbiology. The prize recognizes scientists using microbiology to preserve the global ecosystem, understand terrestrial life and ocean biodiversity, and provide solutions for sustainable marine resource use. Peixoto's research at KAUST focuses on microbiome restoration and rehabilitation through probiotics to protect corals threatened by climate change. Why it matters: This award highlights the importance of KAUST's research in marine science and its potential to provide innovative solutions for coral reef conservation in the Red Sea and beyond.
