Tiny, sun-powered organisms found in freshwater pools could soon fuel Hawaiʻi’s sustainable future. Researchers at the University of Hawaiʻi at Mānoa 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, experts from the College of Tropical Agriculture and Human Resilience (CTAHR) reveal how cutting-edge synthetic biology and metabolic engineering are clearing the way for microalgae production locally and around the world.
