Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
True or False:There are bacteria that can clean up oil spills and this process is called Bioremediation.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Bacteria can be used to clean up oil spills in the ocean through bioremediation. Specific bacteria can be used to bioremediate specific contaminants, such as hydrocarbons, which are present in oil and gasoline.

Detailed explanation-2: -Naturally occurring hydrocarbon-degrading bacteria play an important role in breaking down oil in the event of a spill. Since the mid-1990s a number of these bacteria have been isolated, such as Alcanivorax and Marinobacter.

Detailed explanation-3: -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-4: -Bacteria can break down oil to carbon dioxide and water. However, no single organism can break down all the components of crude oil or refined fuels spilled into the environment. The tens of thousands of different compounds that make up oil can only be biodegraded by communities of microorganisms acting in concert.

Detailed explanation-5: -Nanoenhanced bioremediation is effective on a variety of oil compositions and is minimally impacted by weather. It offers a sustainable alternative to traditional remediation methods, i.e., chemical dispersants, sorbents, and in situ burning, which are often toxic and ineffective.
