Production of carbon dioxide with a biological method

Introduction: Carbon dioxide has a many commercial and industrial applications. In liquid and solid form known as dry ice, carbon dioxide is an important refrigerant, especially in food industry, where they are used during the transportation and storage of ice-cream and other frozen foods. Carbon dioxide is used to produce carbonated soft drinks and soda water.

Carbon dioxide is often used as an inexpensive, non-flammable pressurized gas. Life jackets often have canisters of carbon dioxide for quick inflation.

Steel capsules are also sold as supplies of compressed gas for airguns, paintball markers, and for making seltzer. Rapid vaporization of liquid CO2 is used for blasting in coal mines.

Liquid carbon dioxide is a good solvent for many organic compounds, and is used to remove caffeine from coffee. It has begun to attract attention in the pharmaceutical and other chemical processing industries as a less toxic alternative to more traditional solvents.

In the theater, dry ice is used to produce fog as a special effect: when dry ice added to water, the evaporating mixture of CO2 and cold humid air condenses as a fog. 

 Project description:
In this project you will use a biological method to produce carbon dioxide. You will also observe and record the rate of CO2 production and study at least one condition that may affect the rate of CO2 production.
