Essential Uses Of Microorganisms Biology Essay.
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). This use of microorganisms (mainly bacteria) to destroy or transform hazardous.
Bioremediation is a useful technique for removing contaminants from various environments. In this lesson you'll learn about some of the applications and uses of bioremediation.
This essay will discuss the numerous beneficial microorganisms that carry out processes in biotechnology, agriculture, industries and environment; necessary to sustain life. Firstly, essential uses of microorganisms can be seen in the environment, as they play a vital role in many of the nutrient cycles. For instance, carbon fixation during the.
Bioremediation uses micro-organisms to reduce pollution through the biological degradation of pollutants into non-toxic substances. This can involve either aerobic or anaerobic micro-organisms that often use this breakdown as an energy source. There are three categories of bioremediation techniques: in situ land treatment for soil and.
Premium Essay Bioremediation .to biodiversity has brought public attention to this problem. Bioremediation is a promising approach for recovery of environmental sites contaminated with crude oil and other hydrocarbons. Many microorganisms have been identified to possess hydrocarbon degradation potential. This review covers an overview of common hydrocarbon pollutants, microbes known as.

Bioremediation- cleaning up pollution using bacteria, process that uses microorganisms to degrade harmful chemicals xxii. Decade PCBS, DDT, trichloroethylene and others xxiii. Help.
Bioremediation refers to the process of using microorganisms to remove the environmental pollutants i.e. the toxic wastes found in soil, water, air etc. The microbes serve as scavengers in bioremediation. The removal of organic wastes by microbes for environmental clean-up is the essence of bioremediation. The other names used (by some authors.
Bioremediation is the use of living organisms, primarily microorganisms, to degrade environmental contaminants into less toxic forms. Research has demonstrated that there are very few environments where microbes have not been able to survive, adapt, and indeed, thrive. Microbes are able to utilize a near infinite combination of electron donors and electron acceptors to drive their metabolism.
Bioremediation uses living organisms designed to consume contaminants to help in the recovery or clean up of a contaminated medium.. In both oil spills, microorganisms were used to consume petroleum hydrocarbons and played a significant role in reducing the environmental impact. Bioremediation works where contaminants are not toxic to biological organisms. Bioremediation provides a good.
Bioremediation of explosive contaminated soil “It has been estimated that there are thousands of explosives-contaminated sites within the United States, and even a greater number in Europe and the Soviet Union.”(2) TNT (2,4,6- trinitrotoluene) is one of the most popular explosives used by military forces, and due to improper handling and disposal techniques TNT and its derivatives, have.
In this essay we will discuss about Environmental Biotechnology. After reading this essay you will learn about: 1. Introduction to Environmental Biotechnology 2. Key Points of Environment Biotechnology 3. Bioremediation 4. Microbes and Plants in Environmental Remediation 5. Solid Waste Bio-Treatment 6. Biodegradation of Hydrocarbons 7. Biodegradation of Refractory Pollutants and Waste and.
Bioremediation is any process that cleans an environment degraded by contaminants with the use of microorganisms or other such organisms. The process has been used for many purposes over the centuries. One major use was the desalination of agricultural lands. In modern times, George M. Robinson is credited with being the first person to use bioremediation to solve a major environmental problem.
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. Biological treatment is a similar approach used to treat wastes.
