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 \(\mathrm{O}_{2}\) to produce \(\mathrm{CO}_{2}\) and other carbon-containing compounds that are incorporated into the organism's biomass. How would increasing levels of \(\mathrm{CO}_{2}\) in the environment affect the bioremediation reaction?

Bioremediation is the process in which microorganisms degrade environmental pollutants, such as hydrocarbons. The general reaction for bioremediation can be represented as follows: \[ {\rm Hydrocarbon \: (Pollutant) + \: O_2 \xrightarrow{Microorganism} CO_2 + Biomass} \] In other words, microorganisms use oxygen to convert hydrocarbon pollutants into carbon dioxide and their own biomass.

By applying Le Chatelier's Principle, when the concentration of \(\mathrm{CO}_{2}\) in the environment increases, the reaction system will adjust to minimize the effects of this change.

Increasing the levels of \(\mathrm{CO}_{2}\) in the environment will cause a decrease in the rate of bioremediation, as the reaction will try to counteract the increase in \(\mathrm{CO}_{2}\) concentration. As a result, the equilibrium will shift to the left, reducing the rate at which the pollutant hydrocarbon is degraded, and slowing down the overall bioremediation process. This is an example of how rising \(\mathrm{CO}_{2}\) levels can have negative effects on natural processes that help maintain environmental balance. In conclusion, increasing the levels of \(\mathrm{CO}_{2}\) in the environment would negatively affect the bioremediation reaction by slowing down the process and reducing the rate at which pollutant hydrocarbons are degraded.
