Detailed explanation-1: -Q. * In the biodegradation of oil by aerobic bacteria experiment, why were aquarium pumps used to pump air into the soil sample? Because the air keeps the soil from turning to mud.
Detailed explanation-2: -How Bioremediation Works. Bioremediation relies on stimulating the growth of certain microbes that utilize contaminants like oil, solvents, and pesticides for sources of food and energy. These microbes convert contaminants into small amounts of water, as well as harmless gases like carbon dioxide.
Detailed explanation-3: -Bioremediation is a process where biological organisms are used to remove or neutralize an environmental pollutant by metabolic process.
Detailed explanation-4: -Bioremediation can be defined as any process that uses bacteria, fungi, green plants or their enzymes to return the environment altered by contaminants to its original condition. Bacteria that can degrade some soil contaminants such as chlorinated hydrocarbons are used in bioremediation.
