Description
Jiraporn Sirison and colleagues blast two green microalgae species with ultraviolet-C light to make them richer for food and fuel at once, in a 2026 cultivation study. Stress can push algae to stockpile valuable compounds. Cultures of Desmodesmus quadricauda and Scenedesmus dimorphus received up to three hours of UV-C, then grew for fourteen days while the team tracked biomass, pigments, protein, and fats.
Both species grew more biomass after irradiation, peaking at different doses. Cancer-fighting carotenoid pigments and protein rose, protein by up to about a third. Fat content and productivity crested at one hour of exposure, reaching up to nearly double the untreated level. The fat mix shifted toward oleic acid. The prized omega-3 DHA also appeared for the first time. Biodiesel from the fats met the cetane standard but failed cold-flow requirements, so the authors call for more tuning.
