KAUST researchers have discovered that combining ultraviolet sunlight with phages increases the susceptibility of antibiotic-resistant bacteria to sunlight disinfection. This breakthrough addresses the growing threat of antimicrobial resistance, as the rate of discovering new antibiotics has slowed. The team demonstrated this method's effectiveness against a pathogenic E. coli strain found in Saudi wastewater. Why it matters: This research offers a promising alternative to traditional antibiotics, particularly relevant in regions like Singapore and the GCC where treated wastewater is a crucial water supply source.
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.
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 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 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 analyzed bacterial communities from Deception Island, Antarctica, finding heat-loving bacteria with potential for oil cleanup. Postdoctoral student Junia Schultz is now characterizing the microbiome of extreme terrestrial environments in Saudi Arabia, including volcanoes and deserts. These extremophiles secrete surfactants to break down oil and absorb it into their cells for degradation. Why it matters: This research could lead to efficient and safe methods for cleaning up oil contamination using extremophiles found in both Antarctica and Saudi Arabia.
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 collaborated on a study published in Nature analyzing microbiomes in 170 glacier-fed streams worldwide. The study, led by EPFL, identified a unique microbiome distinct from other cryospheric systems, with almost half the bacteria endemic to specific mountain ranges. KAUST's sequencing efforts helped create a global atlas of these threatened microbiomes. Why it matters: Understanding these microbiomes is crucial for monitoring the impact of climate change on vital freshwater sources originating from glaciers.
