Sorry, preview is currently unavailable. There have been no reports on the bacterium being a pathogen, and since vendors that provide this strain label it as a Biosafety Level 1 organism, it is most probably not harmful to humans, but of course, this is something you should confirm with the vendors when you do purchase the strain. They have tested thousands of bacteria from a variety of sources looking for one that could do the trick. Scientists at the University of Quebec have found that the bacterium, called Alcanivorax borkumensis, uses the key components that make up natural gas and petroleum to energize. Thus, they are used to breakdown harmful substances. Alcanivorax borkumensis is a hydrocarbon degrading bacterium linked to oil degradation around oil spill sites. Certain strains of the organism were found to produce a previously unknown class of glucose lipids that reduce the surface tension of water, and most of their degradation action takes place where oil meets water.

Alcanivorax borkumensis is rod-shaped and is able to grow in highly restricted substrate spectrum. They hope that their new understanding of the biochemistry of the micro-organism will lead to the development of new, effective, environmentally friendly methods to clean up oil-contaminated waters. Alcanivorax borkumensis is a cosmopolitan marine bacterium that uses oil hydrocarbons as its exclusive source of carbon and energy. This study highlights the validity of the assay for the detection at single cell level of key-functional genes involved in the biodegradation of n-alkanes. Are stranger things auditions still open? 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]. Alcanivorax borkumensis is an ubiquitous model organism for hydrocarbonoclastic bacteria, which dominates polluted surface waters.

It belongs to the marine slow-growing hydrocarbonoclastic bacteria group. The small amounts of residue resulting from in situ burning (ISB) of oil on water can cause environmental concerns. One of the University of Quebec scientist who worked toward this goal, Dr Tarek Rouissi, poured over data sheets looking for bacterial strains that could clean up oil spills. Safety. These bacteria become predominant in crude oil-containing waters when nitrogen and phosphorus are supplied ( Kasai et al., 2002 ). After the Deepwater Horizon oil spill, when the equivalent of 4.2 million barrels of oil gushed into the sea off Houston, Texas, Alcanivorax borkumensis unexpectedly helped reduce the environmental impact of the disaster. Alcanivorax borkumensis skyrocketed, helping to get rid of the oil. There have been no reports on the bacterium being a pathogen, and since vendors that provide this strain label it as a Biosafety Level 1 organism, it is most probably not harmful to humans, but of course, this is something you should confirm with the vendors when you do purchase the strain. How does oil spills affect the economy? The bacterium multiplies at a rapid rate in areas with high concentrations of oil compounds.

The bacteria are widespread and are found in barely detectable concentrations wherever even a thin film of oil is present in the ocean, a common phenomenon resulting from natural oil deposits as well as oil spills. 1998 Category: Species Proposed as: sp. Relatively rare in unpolluted seas it quickly comes to dominate the marine microbial ecosystem. Alcanivorax borkumensis, a Gram-negative, rod-shaped chemoorganotroph, is able to use n-alkanes as its principle carbon and energy source by use of the broad spectrum of oil-degrading enzymes it possesses, but they can also use a limited number of organic compounds such as aliphatic hydrocarbons, volatile fatty acids, and pyruvate.

Add a meaning Add Alcanivorax borkumensis details Synonyms for Alcanivorax borkumensis Add synonyms Antonyms for Alcanivorax borkumensis Alcanivorax borkumensis is a marine bacterium that uses exclusively petroleum oil hydrocarbons as sources of carbon and energy (and is therefore designated "hydrocarbonoclastic"). The strain uses aliphatic hydrocarbons as its main carbon source for growth and produces an anionic glucose lipid biosurfactant. Because of its abundance in oil spill regions, it has great potential to be used actively in oil spill remediation. In essence, the microbes break down the ring structures of the hydrocarbons in seaborne oil using enzymes and oxygen in the seawater. You can download the paper by clicking the button above. The approach was further successfully validated on hydrocarbon-contaminated seawater and provided cells abundance (6.74E+04 alkB2-carrying cells mL 1) higher of about one order of magnitude than those obtained by qPCR (4.96E+03 alkB2 gene copies mL 1).

There are many microorganisms that can break down petroleum, the most prominent being hydrocarbonoclastic bacteria. 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. Few studies pointed at some marine microalgae that produce oleophilic compounds (alkanes, long-chain fatty acids, and . They are specialized for hydrocarbon degradation but have an otherwise highly restricted substrate spectrum, being capable of utilizing only a few organic acids like acetate and pyruvate, but not simple sugars, for growth ( 42 ). a1 Strain Isolated from Recovered Bunker Oil Spilt in the Solar I Accident.

It is known to be a surface bacterium leading to substantial interaction with the oil-water interface. Hope this helped. Biosurfactants are surface active molecules that have several applications in petrochemical, food and cosmetics industries, besides an important role in environmental protection, oil spills control, biodegradation, and detoxification of oil contaminated industrial effluents and soil (Khopade et al., 2012). The genus Alcanivorax is known as a petroleum hydrocarbon degrader and primarily contributes to bioremediation process of hydrocarbon pollution in petroleum-contaminated marine environments. What are the consequences of extracting oil? 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. Alcanivorax borkumensis are prominent actors in oil spill bioremediation; however, the interfacial dynamics of their biofilms and its role in oil degradation remain unclear. Longitudinal tracking of biofilm-covered oil microdroplets using microfluidics reveals a spontaneous morphological transition from a thick biofilm phenotype to a thin dendritic phenotype optimized for high oil consumption . The current evidence suggests potential health impacts due to exposure to upstream oil extraction, such as cancer, liver damage, immunodeficiency, and neurological symptoms.Adverse impacts to soil, air, and water quality in oil drilling regions were also identified. Microbial biodegradation is the use of bioremediation and biotransformation methods to harness the naturally occurring ability of microbial xenobiotic metabolism to degrade, transform or accumulate environmental pollutants, including hydrocarbons (e.g. Maggie O'Neill For Dailymail.com While governments, organizations and scientists are struggling to find a key to clean up these oil spills, appearance of oil-degrading bacteria, especially Alcanivorax borkumensis, brings optimism to environmentalists. Swallowing small amounts (less than a coffee cup) of oil will cause upset stomach, vomiting, and diarrhea, but is unlikely to have long-lasting health effects. Bacteria can be used to clean up oil spills in the ocean through bioremediation. Do you know anywhere else to acquire it for cheaper than $300. However, no single organism can break down all the components of crude oil or refined fuels spilled into the environment.
