Bioremediation is the use of microorganisms to degrade environmental pollutants. Many pollutants contain only carbon and hydrogen (oil being one example). The chemical reactions are complicated, but in general the microorganisms react the pollutant hydrocarbon with O2 to produce CO2 and other carbon- containing compounds that are incorporated into the organism's biomass. How would increasing levels of CO2 in the environment affect the bioremediation reaction?
