What are oil eating bacteria?

There are species of marine bacteria in several families, including Marinobacter, Oceanospiralles, Pseudomonas, and Alkanivorax, that can eat compounds from petroleum as part of their diet. In fact, there are at least seven species of bacteria that can survive solely on oil [1].

How are oil eating bacteria used?

Petroleum hydrocarbon-degrading bacteria are ubiquitous in nature and can utilize these compounds as sources of carbon and energy. Bacteria displaying such capabilities are often exploited for the bioremediation of petroleum oil-contaminated environments.

Which bacteria is present in oil?

Table 1

Which bacteria is used to control oil spillage?

Meet Alcanivorax borkumensis, or A. borkumensis for short. This rod-shaped microbe lives in all of the world’s oceans with a special preference for oil-polluted areas, as it uses hydrocarbon molecules for food.

What is the origin of oil eating bacteria?

These bacteria and archaea thrive in the hidden underworld of mud and sediments. You can find them in sunken patches of oil under the sea, in oil and gas seeping out underground, and maybe even in oil reservoirs.

What environmental impact would oil eating bacteria have?

The oil acts as a huge source of food and could produce bacteria “blooms,” or massive population explosions. As the blooms die and decay, they remove oxygen from the Gulf water, jeopardizing the health of fish and other aquatic animals.

How common are oil eating bacteria?

They comprised about 15-20% of the total community of microbes, when quite often you find them at less than 1% abundance. “We’re not sure why this is the case – it could be due to natural seepage of oil from the seafloor, or the release of produced waters from oil rigs.

Can oil eating bacteria live in freshwater?

Bacteria that can consume oil or fuel have been used to help clean up spills in the ocean, but their use in freshwater has been limited by a lack of research.

Which bacteria is called superbug clean oil spills?

Chakrabarty got notable recognition for development of a genetically engineered Pseudomonas, “an oil eating bacteria” also known as “superbug” while working at General Electric Research and Development Center.

How do bacteria degrade oil?

Just like your automobile, these marine-dwelling bacteria and fungi use the hydrocarbons as fuel—and emit the greenhouse gas carbon dioxide (CO2) as a result. In essence, the microbes break down the ring structures of the hydrocarbons in seaborne oil using enzymes and oxygen in the seawater.

How do microbes digest oil?

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.

What effect did the bacteria have on the oil?
