What are the uses of phytoremediation in life?
Phytoremediation uses plants to clean up contaminated environments. Plants can help clean up many types of contaminants including metals, pesticides, explosives, and oil. However, they work best where contaminant levels are low because high concentrations may limit plant growth and take too long to clean up.
What is the application of bioremediation?
Bioremediation is a branch of biotechnology that employs the use of living organisms, like microbes and bacteria, in the removal of contaminants, pollutants, and toxins from soil, water, and other environments. Bioremediation is used to clean up oil spills or contaminated groundwater.
What is phytoremediation and its types?
There are five basic types of phytoremediation techniques: 1) rhizofiltration, a water remediation technique involving the uptake of contaminants by plant roots; 2) phytoextraction, a soil technique involving uptake from soil, 3) phytotransformation, applicable to both soil and water, involving the degradation of …
What is phytoremediation explain its types with suitable examples?
What is bioremediation and its applications in microbiology?
Bioremediation can be defined as any process that uses bacteria, fungi, green plants or their enzymes to return the environment altered by contaminants to its original condition.
What are the advantages of bioremediation and phytoremediation?
There are several advantages of using bioremediation processes compared with other remediation technologies: (1) biologically-based remediation detoxifies hazardous substances instead of merely transferring contaminants from one environmental medium to another; (2) bioremediation is generally less disruptive to the …
What are some application of a bioremediation?
Bioremediation techniques are used to degrade highly toxic metals, chemicals, effluents and pollutants from the environment. Heavy metals from tanneries if not degraded by algae produce toxic oxides; these oxides produce lungs cancer, asthma, paralysis, brain damage, memory loss etc.
What is the application of biology in bioremediation?
An important early application of molecular biology to the study of bioremediation was the evaluation of 16S rRNA genes in contaminated environments, which provided an indication of the microorganisms that naturally inhabited these environments or became important when the environment was manipulated to accelerate …
What are the main types of phytoremediation techniques?
What is phytoremediation and its type?
Phytoremediation is a cost-effective, plant-based approach to remediation that takes advantage of the ability of plants to concentrate elements and compounds from the environment and metabolize various molecules in their tissues.
What is phytoremediation?
Phytoremediation 4 Phytoremediation consists of mitigating pollutant concentrations in contaminated soils, water, or air, with plants able to contain, degrade, or eliminate metals, pesticides, solvents,explosives, crude oil and its derivatives, and various other contaminants from the media that contain them. 6.
What is phytotransformation and why is it important?
23. 3.Phytotransformation Definition: Also known as phytodegradation, it is the breakdown of contaminants taken up plants by metabolic processes within the plant. ● Remediate some organic contaminants, such as chlorinated solvents, herbicides, and munitions ● It can address contaminants in soil, sediment, or groundwater. 24. 3.
What is Phytostimulation?
Phytostimulation (Rhizodegradation) Definition: Breakdown of contaminants within the plant root zone, or rhizosphere. ● Carried out by bacteria or other microorganisms flourishing in the rhizosphere. ● Microbes in rhizosphere transform contaminant to non toxic product. ● Works well in the removal of petroleum hydrocarbons 26. 4.
What is phytoconcentration or phytoextraction?
Phytoextraction or phytoconcentration, where the contaminant is concentrated in the roots,stem and foliage of the plant, 2. Phytodegradation, where plant enzymes help catalyze breakdown of the contaminantmolecule, 3.
