How are microbes used to clean oil spills?
During an oil spill, these low-abundance microbes sense hydrocarbons and move toward the source. There they flourish and reproduce. However, GoMRI researchers did find evidence of anaerobic hydrocarbon degradation, suggesting that even in these environments, microbes are working to break down the spilled oil.
Which species of genetically engineered microorganisms is successful in bioremediation of oil spills?
Organisms that produce enzymes capable of degrading petroleum are useful in cleaning up oil spills. Some common ones that break down oil are genetically engineered species of Pseudomonas and Azotobactera.
What type of bacteria eats oil?
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.
Why microorganisms are used in bioremediation?
Microorganisms are suited to the task of contaminant destruction because they possess enzymes that allow them to use environmental contaminants as a food. For bioremediation to be effective, microorganisms must enzymatically attack the pollutants and convert them to harmless products.
What group of microorganisms are used for bioremediation reducing toxic wastes from the environment?
Deinococcus radiodurans is a radiation-resistant extremophile bacterium that is genetically engineered for the bioremediation of solvents and heavy metals. An engineered strain of Deinococcus radiodurans has been shown to degrade ionic mercury and toluene in radioactive mixed waste environments [7].
What is ex situ bioremediation?
Ex-situ bioremediation is a biological process in which excavated soil is placed in a lined above-ground treatment area and aerated following processing to enhance the degradation of organic contaminants by the indigenous microbial population.
