THE ETHANOL INDUSTRY WASTE AS A VALUABLE FEEDSTOCK FOR HYDROGEN PHOTOPRODUCTION BY GREEN ALGAE $CHLORELLA~VULGARIS$

Abstract

Green algae are promising objects of biotechnology due to their high growth rates and the ability to produce biologically active compounds. Moreover, green algae are able of generating biohydrogen (H2), which is of interest in biofuels technology. In this study an application of distillers grains with solubles (DGS), the main waste generated during ethanol production, as a feedstock for enhancing the yield of H2 in green alga Chlorella vulgaris IBCE C-19 was investigated. The results obtained showed the possibility of using of this waste as a valuable source of natural biological compounds in H2 production.
