Biofuel production from algal biomass is a practical means of reducing carbon dioxide emissions. However, high production costs are a major drawback. Microalgae are known to contain functional substances, such as antioxidants, natural pigments, and polyunsaturated fatty acids, which contribute to a healthy life when used as cosmetics, dietary supplements and animal feed, are already available in the market. The aim of this project is to create a brand new biorefinery that will reduce production costs and enable commercial use of biofuels. This can be accomplished through the cost-efficient production of useful substances and lipid components obtained from screening 3,000 strains of the microalgae library.
