Two professors from the University of Arizona, US, are developing a cost-effective, spirulina-based nutrition solution in bioreactors to combat global food insecurity and malnutrition, especially in climate-affected regions. Dr. Floyd Chilton, professor and director at the Center for Precision Nutrition and Wellness, and Dr. Joel Cuello, professor at the Department of Biosystems Engineering at the College of Agriculture, Life and Environmental Sciences, are working to help people with the blue-green microalgae.“We are facing an existential crisis,” says Chilton. “The world population will be around 10 billion people by 2050. That means we need to increase food production to feed those people. And we must do that in the face of climate change, which is reducing our capacity.”
