In simple words, bioremediation is a process of environmental improvement, in which organisms play a key role. Organisms adapt to their surrounding conditions over the time. So, many microorganisms developed a way to use certain environmental pollutants as food sources and finally, to obtain energy.
Definition of bioremediation: the treatment of pollutants or waste (as in an oil spill, contaminated groundwater, or an industrial process) by the use of microorganisms (such as bacteria) that break down the undesirable substances Examples of bioremediation in a Sentence.Bioremediation has been described as “a treatability technology that uses biological activity to reduce the concentration or toxicity of a pollutant. It commonly uses processes by which microorganisms transform or degrade chemicals in the environment” (King 1).Bioremediation is a process used to treat contaminated media, including water, soil and subsurface material, by altering environmental conditions to stimulate growth of microorganisms and degrade the target pollutants. In many cases, bioremediation is less expensive and more sustainable than other remediation alternatives.
Bioremediation process using microorganisms is a kind of nature-friendly and cost-effective clean green technology. Recently, biodegradation of industrial wastes using enzymes from marine microorganisms has been reported worldwide. The prospectus research activity in remediation area would contribute toward the development of advanced bioprocess technology. To minimize industrial wastes.
This essay discusses student difficulties with writing in English from examining five student writing samples, and proposes remediation possibilities via a process approach to writing. Following from the introduction is an overview of the process approach to writing employed in this essay.
The term bioremediation very effectively describes its most important characteristic which is the use of living microorganisms for the improvement of the environment and maintaining a homeostasis in the ecosystem. It is used to clean up a vast range of hazardous waste from industries, farms, cities etc.

Bioremediation is the use of microbes to clean up contaminated soil and groundwater. Microbes are very small organisms, such as bacteria, that live naturally in the environment. Bioremediation stimulates the growth of certain microbes that use contaminants as a source of food and energy.
Bioremediation is defined as the process whereby organic wastes are biologically degraded under controlled conditions to an innocuous state, or to levels below concentration limits established by regulatory authorities (2) For bioremediation to be effective, microorganisms must enzymatically attack the pollutants and convert them to harmless products. As bioremediation can be effective only.
In the previous article, bioremediation processes involved in treatment and removal of oil hydrocarbon pollutants was discussed.In the present article, the problem of plastic pollution and associated bioremediation solutions are reviewed. Plastic waste or debris are one of the most hazardous pollutant entering the seas and oceans, after oil spills and sewage discharge.
Definition Bioremediation is the use of microbes, fungi or plants to remove toxic contaminants from a site. This can be accomplished in situ or ex situ. In situ bioremediation involves remediating the contaminant at the site of contamination.
Examples of how to use “bioremediation” in a sentence from the Cambridge Dictionary Labs.
Thus, bioremediation systems for dealing with soils contaminated by spilled gasoline or petroleum can be based on simple tillage and fertilization. Similarly, petroleum refineries may utilize a bioremediation process called land farming, in which oily wastes are spread onto land, which is then tilled and fertilized until microbes reduce the residue concentrations to an acceptable level.
Bioremediation is a technology that utilizes the metabolic potential of microorganisms to clean up contaminated environments. One important characteristic of bioremediation is that it is carried out in non-sterile open environments that contain a variety of organisms. Of these, bacteria, such as those capable of degrading pollutants, usually.
Bioremediation Technology Market Demand and Production Report 2019 to 2025 - A new report available with decisiondatabases.com on Bioremediation Technology Market which provides an in-depth analysis during the forecast period. This report focuses on top manufactures with capacity, production, price, revenue and Market share.
Bioremediation occurs when prokaryotes clean up a polluted environment through the natural breakdown of pollutants. Microbial bioremediation is the use of prokaryotes (or microbial metabolism) to remove pollutants. Certain toxic metals and oxides, such as selenium and arsenic compounds, can also be removed from water by bioremediation. Mercury is an example of a toxic metal that can be removed.
This will allow easy passage of nutrients suitable for the development of the microorganism. Bioremediation techniques. The nature of the contaminants determines the technique used on the site of contamination. Bioremediation strategies require two broad procedures. In-situ and Ex-situ are two major techniques employed in bioremediation processes. In-situ bioremediation is used when the.
