\"microalgae\"<\/p>\n

Tiny, sun-powered organisms found in freshwater pools could soon fuel Hawaiʻi<\/span>\u2019s sustainable future. Researchers at the University of Hawaiʻi<\/span> at M\u0101noa are charting a path to transform microalgae into a “green gold” reality for biofuels, medicine and nutrition. In a study published in Plant Biotechnology Journal<\/em><\/a>, experts from the College of Tropical Agriculture and Human Resilience<\/a> (CTAHR<\/abbr>) reveal how cutting-edge synthetic biology and metabolic engineering are clearing the way for microalgae production locally and around the world.<\/p>\n

Microalgae excel at capturing carbon dioxide and converting it into high-value compounds such as lipids (oils) and terpenoids (organic chemicals). These can be used to create everything from renewable jet fuel to life-saving medications.<\/p>\n

“Microalgae have immense potential because they don’t compete with food crops for land or fresh water,” said Zhi-Yan (Rock) Du, an associate professor in CTAHR<\/abbr>\u2019s Department of Molecular Biosciences and Bioengineering (MBBE<\/abbr>) and the study\u2019s lead author. “Our research focuses on how we can ‘reprogram’ these organisms to produce more of these valuable materials efficiently.”<\/p>\n

Tweaking internal chemistry<\/h2>\n

Despite their potential, producing microalgal products at a scale that can compete with petroleum has been difficult. The 糖心视频<\/abbr> team, including graduate students led by Ty Shitanaka (co-principal investigator with MBBE<\/abbr> professor Samir Kumar Khanal), examined how new genetic tools such as CRISPR\/Cas9 can optimize the “metabolic superhighways” within the algae.<\/p>\n

By tweaking the internal chemistry of the cells, researchers can drive the algae to accumulate higher concentrations of oil and specific health-boosting compounds without slowing down their growth, a common problem in earlier bioengineering attempts.<\/p>\n

A sustainable vision for Hawaiʻi<\/span><\/h2>\n

For Hawaiʻi<\/span>, the state’s year-round sunshine and coastal access provide an ideal environment for algae cultivation.<\/p>\n

“This has the potential to help Hawaiʻi<\/span> create a more resilient, energy-independent economy,” said Khanal. “By integrating microalgae production with wastewater treatment or agricultural byproduct recycling, we can create a system that is both environmentally friendly and economically viable.”<\/p>\n

The study also emphasizes the importance of “synthetic biology,” which allows scientists to design biological parts that don’t exist in nature, further pushing the boundaries of what microalgae can produce.<\/p>\n

The research was a collaborative effort involving Professor Krzysztof Zienkiewicz from the Nicolaus Copernicus University in Toru\u0144, Poland.
