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: -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.
Detailed explanation-3: -Among bacteria involved in bioremediation processes, most belong to the genera Alcaligens, Achromobacter, Acinetobacter, Alteromonas, Arthrobacter, Burkholderia, Bacillus, Enterobacter, Flavobacterium, Pseudomonas [22, 23].
Detailed explanation-4: -Bioremediation helps clean up water sources, create healthier soil, and improve air quality around the globe. But unlike excavation-based remediation processes, which can be disruptive, bioremediation is less intrusive and can facilitate remediation of environmental impacts without damaging delicate ecosystems.
Detailed explanation-5: -Bioremediation is a technique used to remove environmental contaminants from the ecosystem. It utilizes the biological mechanisms inherent in microbes and plants to eradicate hazardous pollutants and restore the ecosystem to its original condition [9].
