What had just happened?
Put your caption here. But, why sir? BIOLOGIST Don’t worry Charlie and Selena. Well, I’m a biologist in biotech field. We will use the application of ‘superbug’.
- What is superbug bacteria? It also enhance the effect of oil degradation & bioremediation to ecosystem. It is known as oil-eating bacteria. You see, Biotechnology can be used to modify some microorganisms to metabolise oil spills, extract minerals & degrade potentially toxic waste from environment.
That’s cool! Sir, can you tell me about the major hydrocarbon degrading microbe? Well, it includes Pseudomonia sp. , Alanivorax sp. , Bacillus sp. and many more. How does the environmental clean-up occurs? These bacteria oxidize hydrocarbon molecules CO₂ and H₂O.
Well, they are used by bacteria for growth and development. Then, how about the intermediate products formed?
PRODUction of ‘superbug’ bacteria
I will watch his videos online in the evening. Sure, ANAND MOHAN CHAKRABARTY who is a microbiologist is the pioneer for this development. Sir, can you tell me about the development of this oil eating ‘SUPERBUG’
- He used 4 strains of pseudomonas with different type of plasmids from each strain . He inserted 4 plasmid into 1 strain of pseudomonas putida strain G, which has the capability to degrade camphor & octane. Thank you for your precise explanation, sir. You are welcome !
Finally, the oil spill was cleant up! Fuh...Sigh of relief.
Remediation of superbug bacteria is the process used to make the environment safe by absorbing or destroying contaminants which is the oil spill found in the sea. Toxic chemicals such as polycyclic aromatic hydrocarbons (PAHs), the aromatics which tend to be the molecular compounds in oil are the most toxic to marine life and can also be quite tenacious in the environment. Bioremediation is an eco-friendly process of cleaning pollutants using genetically engineered microbes or the superbug.
These micoorganism can degrade toxic chemicals by transferring plasmids responsible for different characteristics, making them superbugs. The aim to combine unique characteristics from envolving microbes and construct strains of superbugs for bioremediation in both aquatic and terrestrial ecosystems.
Examples of superbug bacteria: Alcanivorax Cycloclasticus Pseudomonas putida: A genetically engineered oileating bacteria developed by Professor Ananda Mohan Chakrabarty
the process for cleaning up an oil spill using superbug bacteria. A special OEM-containing solution is applied to the spill. The solution breaks down the oil to molecule size, thus increasing the surface area. The increase in surface area begins the oxygenation process; this revives dormant microbes so they will begin feeding on the hydrocarbons. Nutrients in the OEM solution help these activated microbes survive.
the benefits of using Superbug bacteria? Oil has the potential to cause short-term environmental damage. Though it is not considered a hazardous waste, crude oil coats and kills sea life and damages the surrounding beaches, rocks, trees, etc. If left to nature, oil spills will continue to plague local ecosystems indefinitely.
Application of Superbug Bacteria The Deepwater Horizon Oil Spill (2010) Microbial communities were monitored for their role in the natural degradation of the oil spill. One of the bacteria used is superbug bacteria. Exxon Valdez Oil Spill (1989) Bioremediation was one of the techniques applied to remediate the oil spill in Alaska. Nutrient addition (biostimulation) was used to accelerate the biodegradation of oil in the affected shorelines. Gulf War Oil Spill (1991) Bioremediation, through both biostimulation and bioaugmentation, was utilized to deal with oil contamination in the Persian Gulf. Oil spill can leads to serious problem if no quick action is taken.
THE END!
