Preliminary studies of biorefinery: Integration of slurry and CO2 gas as biomethane digester waste for microalgae Scenedesmus sp. growth

Bio-methane as renewable energy can generate slurry waste and CO2. Utilization of slurry has been examined in previous studies. Slurry digester which is made from seed cake Jatropha curcas, JatroMas cultivars can improve the growth of microalgae Scenedesmus sp. compared to standard media. CO2 gas...
