Detailed explanation-1: -Biodegradation is a process by which microorganisms such as bacteria, fungi, and yeast break down complex compounds into simpler products. Biodegradation of oil is a natural process that slowly removes oil from the aquatic environment.

Detailed explanation-2: -Bioremediation of petroleum contaminated environments is a process in which the biological pathways within microorganisms or plants are used to degrade or sequester toxic hydrocarbons, heavy metals, and other volatile organic compounds found within fossil fuels.

Detailed explanation-3: -Bioremediation is any process that uses decomposers and green plants, or their enzymes, to improve the condition of contaminated environments. Bacteria can be used to clean up oil spills in the ocean through bioremediation.

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.

Detailed explanation-5: -These bacteria are known as hydrocarbon degrading bacteria. Pseudomonas can digest the hydrocarbons in oil. They are gram negative bacteria that are found in soil, water and plants and animals. A species called Pseudomonas putida is widely used in oil spill decontamination or bioremediation.
