In a research study conducted at the University of Nottingham School of Biosciences, a team of scientists has uncovered how to refine seawater to produce bioethanol. When fermented, marine yeast of the Saccharomyces cerevisiae AZ65 strain and yeast extract peptone dextrose (YPD) aid in the production of biofuels. Not only is this discovery key in the development of renewable energy sources, but it also reduces the water footprint of ethanol. Through the use of seawater, the traditional biorefinery methods that rely on agriculture and freshwater become obsolete and limit further depletion of the existing freshwater supplies. Additionally, this new method for biofuel production creates greater opportunities for individual countries to become more sustainable as they switch into biofuel production.
