Bacteria can live on almost anything – some even on oil. Friedrich Widdel, Director at the Max Planck Institute for Marine Microbiology, is studying microbes that break down oil hydrocarbons without oxygen, deep down in the sediment.
What effect does bacteria have on 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 is the use of Alcanivorax bacteria?
Of all the Alcanivorax species and other oil-degrading microbes, Alcanivorax borkumensis is one of the most important worldwide due to the fact it produces a wide variety of very efficient oil-degrading enzymes. With this knowledge, A. borkumensis could provide a useful tool for bioremediation of oil spills.
Where is Alcanivorax found?
Alcanivorax borkumensis (A. borkumensis) is a Gram-negative, rod-shaped hydrocarbonoclastic (“oil-degrading”) bacterium. It thrives in halophilic, aerobic environments and is found in the upper layers of freshwater or marine environments such as the Mediterranean Sea, Pacific Ocean and Arctic Sea [4, 8].
How does Alcanivorax borkumensis clean up oil spills?
After a disastrous deep-sea oil spill, a bacteria was discovered at great ocean depths, feasting on the oil. Now known as Alcanivorax borkumensis, the bacteria was able to digest oil by breaking down petroleum hydrocarbons with the use of special enzymes — something no other known bacteria can do.

What size are most bacteria?
Bacterial cells range from about 1 to 10 microns in length and from 0.2 to 1 micron in width. They exist almost everywhere on earth. Some bacteria are helpful to humans, while others are harmful.
What organism can help clean up oil spills and radioactive spills?
Scientists know that marine bacteria can assist in cleaning up after oil spills.
What organism can help clean up oil spills and radioactive?
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 type of organism do humans use to help clean up oil spills?
How do bacteria clean up oil? Bacteria, however, may be a better solution for cleaning up oil. Scientists have discovered a rod-shaped bacteria that need oil for energy. These bacteria populate the area where the oil spill occurs.
When was Alcanivorax discovered?
The most closely studied of these rod-shaped bacteria, Alcanivorax borkumensis, was first identified in 1998 near the Isle of Borkum in the North Sea. It has several efficient enzymes that break down a variety of the components of crude oil called alkanes.
What is the role of a Borkumensis in bioremediation?
One of the most useful and interesting examples of the use of prokaryotes for bioremediation purposes is the cleanup of oil spills. … Some species, such as Alcanivorax borkumensis, produce surfactants that solubilize the oil (making it soluble in water), whereas other bacteria degrade the oil into carbon dioxide.
What type of microbe is Alcanivorax borkumensis?
Alcanivorax borkumensis is a cosmopolitan marine bacterium that uses oil hydrocarbons as its exclusive source of carbon and energy. Although barely detectable in unpolluted environments, A. borkumensis becomes the dominant microbe in oil-polluted waters.
