KAUST researchers cultivated the extremophile microalga Cyanidioschyzon merolae, which thrives in hot, acidic conditions, using commercial fertilizer at lab and outdoor large-scale culture. This was part of the Development of Algal Biotechnology in the Kingdom of Saudi Arabia (DABKSA) project, a collaboration between MEWA and KAUST. The microalgae consume pollutants and CO2 to produce biomass like proteins and oils, which can be used as sustainable animal feed. Why it matters: This positions Saudi Arabia as a potential leader in algal technologies, strengthens food independence, and contributes to the country's carbon net-zero goal by 2060.
KAUST researchers analyzed the genome of strain RS24, a bacterium isolated from the Red Sea. The bacterium, named Candidatus Micropelagos thuwalensis RS24, belongs to the PS1 clade within Alphaproteobacteria. Genome sequencing revealed that RS24 and IMCC14465, while similar, are distinct species of the PS1 clade, containing genomic islands. Why it matters: This study advances understanding of microbial adaptation to extreme marine environments like the Red Sea, providing insights into the structure-function relationships within microbial communities.
KAUST researchers discovered a five-hectare bio-sedimentary formation of living stromatolites off Sheybarah Island in the Red Sea. These structures are microbial carbonates similar to fossils of early life and are only the second group found in normal marine settings. The stromatolites host a diverse microbial community, including reticulated filaments previously only found in caves. Why it matters: The discovery provides insights into early life on Earth and has implications for understanding potential life formation on Mars, while also creating a unique educational opportunity for tourism in Saudi Arabia.
KAUST researchers have developed new techniques to produce nutritious microalgae in industrial volumes using seawater-adapted Spirulina and Chlorella strains. This innovation eliminates the need for freshwater, making algae-based livestock feed production sustainable and economically viable. The new Saudi Center for Algal Biotechnology Development and Aquaculture will scale up operations from a 1,000 square meter pilot plant to 42,000 square meters. Why it matters: This could help Saudi Arabia decrease its dependency on imported feed and raw food materials, aligning with its Vision 2030 goals for increased domestic food security.
A KAUST-led team mapped the genome of the orange clownfish using the university's Supercomputing and Bioscience Core Labs. The genome contains 26,597 protein-coding genes and is available via the Nemo Genome DB database. The clownfish genome is one of the most complete fish genomes ever produced, comprising approximately 939 million nucleotides. Why it matters: This genomic map provides a crucial resource for understanding reef fish biology and responses to environmental changes like climate change.
KAUST Research Scientist Dr. Ram Karan received a Young Scientist Award at the 15th International Congress on Thermophiles in Japan for his work on extremozymes from Red Sea brine pools. His research focuses on identifying, purifying, and bioengineering microbial proteins from these pools. He utilizes single-amplified genomes (SAGs) to produce extremozyme proteins without needing to grow cells in the lab. Why it matters: This award recognizes KAUST's innovative research into extremophiles, which have the potential to develop novel, sustainable biotechnical processes for industrial applications.
KAUST researchers discovered that the red algae strain Galdieria yellowstonesis can convert sugars from chocolate-processing waste into C-phycocyanin, a valuable blue pigment. The study found that high levels of carbon dioxide promote Galdieria growth, and the resulting phycocyanin was deemed food-safe by the U.S. FDA. Mars supported the research by providing chocolate samples. Why it matters: This research offers a sustainable method for waste management and contributes to a circular economy in the region, with potential applications in food, cosmetics, and pharmaceuticals.
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.
