Abstract: In this work, a cooperative algal-bacterial system that efficiently upgrade biogas, simultaneously reduce the biogas slurry nutrient, and exhibits high biomass productivity, was developed. The method about removing H2S and CO2 from biogas by three microalgal strains (Chlorella vulgaris, Scenedesmus obliquus, and Neochloris oleoabundans) mixed with activated sludge using biogas slurry as nutrient medium.
