Popis:	In this study, a culture system with outdoor microalgae-incorporating photobioreactors was utilized to upgrade biogas produced from the anaerobic digestion of swine wastewater. Using ethyl methane sulfonate (EMS) random mutagenesis, we isolated a mutant strain of microalga, Chlorella sp. MB-9, which was tolerant to high CH4 and CO2. In the field study of outdoor operation, the maximum growth rates of Chlorella sp. MB-9 aerated with desulfurized biogas at 0.05, 0.1, 0.2 and 0.3 vvm were 0.32, 0.311, 0.275 and 0.251 g L−1 d−1. In addition, ∼70% of the CO2 in desulfurized biogas (∼20% CO2, ∼70% CH4, and H2S
