The emission of gases CO2 and CH4 are considered one of the major responsible about global warming and climate change, although the expanding use of fossil fuels and changes in land use are also among the causes. Among these emissions, CO2 represents 63%, with CH4 and N2O representing the 24% and 3%, respectively. These gases are typically converted into electricity and low value heat, but also can be microbially transformed into valuable bioproducts. There are many reports focusing in CO2 or CH4 microbial sequestration, but to enable microbial conversions of both biogases into bioproducts, a microbial consortium involving algae and bacteria can be used.  Together, these microorganisms could rapidly metabolize high concentrations of CO2 and CH4, transforming them in valuable bioproducts.
