What is biostimulation used for?
Biostimulation refers to the addition of rate limiting nutrients like phosphorus, nitrogen, oxygen, electron donors to severely polluted sites to stimulate the existing bacteria to degrade the hazardous and toxic contaminants.
What are some examples of bioremediation?
Some examples of bioremediation related technologies are phytoremediation, bioventing, bioattenuation, biosparging, composting (biopiles and windrows), and landfarming. Other remediation techniques include, thermal desorption, vitrification, air stripping, bioleaching, rhizofiltration, and soil washing.
What are the disadvantages of bioremediation?
The main disadvantage of bioremediation technology is that it is restricted to biodegradable compounds. Further, researchers have revealed that sometimes the new product developed after biodegradation may be more toxic to the environment than the initial compound.
What is the process of biostimulation?
Biostimulation involves the modification of the environment to stimulate existing bacteria capable of bioremediation. This can be done by addition of various forms of rate limiting nutrients and electron acceptors, such as phosphorus, nitrogen, oxygen, or carbon (e.g. in the form of molasses).
What microorganisms are used in bioremediation?
In bioremediation, microorganisms with biological activity, including algae, bacteria, fungi, and yeast, can be used in their naturally occurring forms.
Who benefits from bioremediation?
Bioremediation helps clean up water sources, create healthier soil, and improve air quality around the globe. But unlike excavation-based remediation processes, which can be disruptive, bioremediation is less intrusive and can facilitate remediation of environmental impacts without damaging delicate ecosystems.
What are 4 advantages of bioremediation?
The major benefits of bioremediation are: Completely natural process with almost no harmful side effects. Carried out in situ for most applications with no dangerous transport. Quick turnaround time to make soil and water useful.
