Which bacteria is used for bioremediation of oil spill?
Many genera of plant, microbes, and fungi have demonstrated oil remediating properties including Spartina, Haloscarcia, Rhizophora, Nocardioides, Dietzia, and Microbacterium.
Which bacteria is used in biodegradation?
Bacteria with the ability to degrade hydrocarbons are named hydrocarbon-degrading bacteria. Biodegradation of hydrocarbons can occur under aerobic and anaerobic conditions, it is the case for the nitrate reducing bacterial strains Pseudomonas sp. and Brevibacillus sp.
Which bacteria can degrade oil?
Recent studies have identified bacteria from more than 79 genera that are capable of degrading petroleum hydrocarbons (Tremblay et al., 2017); several of these bacteria such as Achromobacter, Acinetobacter, Alkanindiges, Alteromonas, Arthrobacter, Burkholderia, Dietzia, Enterobacter, Kocuria, Marinobacter.
How is oil contamination being degraded by microbes?
There are the two main approaches to oil spill bioremediation: (a) bioaugmentation, in which known oil-degrading bacteria are added to supplement the existing microbial population, and (b) biostimulation, in which the growth of indigenous oil degraders is stimulated by the addition of nutrients or other growth-limiting …
How are bacteria used in oil spills?
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. If feathers come into contact with oil, the seabird ingests the oil while trying to preen.
What is aerobic biodegradation?
Aerobic biodegradation is the breakdown of organic contaminants by microorganisms when oxygen is present. Many organic contaminants are rapidly degraded under aerobic conditions by aerobic bacteria called aerobes. Aerobic bacteria (aerobe) have an oxygen based metabolism.
Which bacteria can decompose the oceanic oil spills?
A species called Pseudomonas putida is widely used in oil spill decontamination or bioremediation. It is known to break down many aromatic compounds like hydrocarbons.
What is oil biodegradation?
Biodegradation is the process in which living organisms, most often microorganisms, break down material into simpler components. The aromatic compounds in oil are toxic to living organisms and such spills can render havoc in an ecosystem. Natural seepages from unexplored oil sources is another source of contamination.
How does oil decompose?
As soon as oil enters the water it begins to break down through a complex mix of processes known as weathering: spreading, evaporation, dispersion, emulsification, dissolution, oxidation, sedimentation/sinking, and biodegradation. Spreading of oil over the surface of the water is a relatively rapid process.
How are organic contaminants degraded under aerobic conditions?
Many organic contaminants are rapidly degraded under aerobic conditions by aerobic bacteria called aerobes. Aerobic bacteria (aerobe) have an oxygen based metabolism. Aerobes, in a process known as cellular respiration, use oxygen to oxidize substrates (for example sugars and fats) in order to obtain energy.
What are the benefits of aerobic and anaerobic biodegradation?
The aerobic process also improves the environment of the workers and the animals and helps to keep pathogens in check. Anaerobic Biodegradation Anaerobic digestion occurs when the anaerobic microbes are dominant over the aerobic microbes.
What is the final product of biodegradation?
Biodegradation processes vary greatly, but frequently the final product of the degradation is carbon dioxide or methane. Organic material can be degraded aerobically , with oxygen, or anaerobically , without oxygen.
What are the biochemical processes of microbial organisms?
For those interested in the biochemical processes of the microbial organisms this document will provide a high level explanation of the aerobic and anaerobic processes. Biodegradation Biodegradation is the process by which organic substances are broken down into smaller compounds by the enzymes produced by living microbial organisms.
