Bioremediation is the technique of using living organisms to clean up contamination in land and water is called bioremediation. A subset of bioremediation is phytoremediation (technique of using plants as environmental clean-up remedies. petroleum industry employs bacteria to clean up after oil spills and leaks have occurred. oil-loving bacteria break down the chemicals into natural substances, including carbon dioxide gas, a type of alcohol, and water. Bioremediation, while safe relies on natural

Plants that help in bioremediation are rhizophores, mangroves, lemnia, Spartina etc. METHODOLOGY: 1) Sampling of the soil and Field study – Type of area to be treated and bio monitoring of the field to decide whether bioremediation is possible mainly by pre-treatment assessment. 2) Pre treatment
much of the surrounding life. Bioremediation offers an efficient solution for cleaning up oil spills. The pollutants are biologically degraded by complete mineralization of the organic contaminants, turning the toxic waste into harmless products such as carbon dioxide, water, inorganic compounds, and cell protein (Das & Chandran, 2010). Although contaminants could be removed by physical means, this does not dispose of the dangerous petroleum hydrocarbons. Bioremediation can clean up our oceans without
Over 39 years have passed since the nationwide ban of a well-known pesticide, dichlorodiphenyltrichloroethane (DDT) (1), yet it still has an important role in public health as well as the environment. DDT is a persistent toxin, having a long half-life of 2 to 15 years terrestrially and 150 years aquatically (as cited in 5). It was originally used in World War II to control malaria and yellow fever then became a main staple in pesticide control for crops. Because DDT was a highly effective pesticide
stressed environment, and the advantages and disadvantages of using plants for bioremediation. Examples of emerging technology in the ever-evolving field of phytoremediation will also be discussed. Phytoremediation is characterized by the use of vegetative species for in situ treatment of land areas polluted by a variety of hazardous substances. (Sykes et al., 1999) Plants are especially useful in the process of bioremediation because they prevent erosion and leaching which can spread the toxic substances
environment.” This statement is often used to describe the fundamental aim of bioremediation around the world. Richard Raymond, who is thought by some the father of bioremediation, foresaw that “adding acclimated microorganisms to contaminated sites could become a common practice” thus benefiting society by attacking the pollutants and converting them into harmless products to humanity and animal habitat. Bioremediation technologies can be generally classified as ex situ in which treatments involve
Soil remediation is part of a broader effort known as environmental remediation. It restores previously contaminated land to an uncontaminated state and is an important part of sustainable development, especially in respect of resource management and reducing reliance on landfill (Scottish Environment Protection Agency, n.d., p. 4). Most countries around the world are actively engaged in some form of soil remediation. Each year in the European Union, several billion euros are expended on the remediation
solve the problem and “Bioremediation” means to solve the problem with the help of biological agents The term Bioremediation has been introduce to describe the process of removing of toxic waste from environment with the help of microorganisms. Bioremediation is most effective management technique to reduce the contamination of soil and recoveration of contaminated soil. Bioremediation is natural and successful cleaning technique for polluted environment. Now a day bioremediation is widely accepted
The word “remediate” means to solve a problem, so the word “bioremediation” refers to the use of biological organisms to solve an environmental problem. Bacteria, fungi, protists and other microorganisms in a non-polluted environment are constantly breaking down organic matter, and when the soil is polluted, some of the organisms may die, but others will still be able to break down the pollutants. Bioremediation provides organisms that can consume the pollutants with fertilizer, oxygen, and other
intensive agriculture and other human activities cause soil degradation, pollution and lowers the productivity and sustainability of the crops that further increase the pressure on natural resources and contribute to their degradation. Environmental bioremediation is an effective management tool for managing the polluted environment and in restoring the contaminated soil. The use of microbial sources, coupled with advanced technology is one of the most promising and economic strategies for the removal of
community is bioremediation. Bioremediation is the application of microorganisms or biological enzymes to treat or remove contaminants. (“In Situ Bioremediation,” para. 1) Bioremediation is a lower cost and more effective option than removing contaminated soil offsite as a preventative measure, before the contaminants reach groundwater. When contaminants reach ground water bioremediation is still an excellent option, but it takes a longer period of time to remove the contaminants. Bioremediation is a sustainable
will first come to our mind. With the development of recombinant DNA technology, metabolic potentials of microorganisms are being explored. Nowadays, genetically modified microorganisms (GMMs) have vast applications in human and animal health, bioremediation, and in industries such as food and textiles. The first GMM, specifically E. coli, was made in the 1970s (Teisha, 2013). A few years later, GMMs which produced essential human proteins were churned out by researchers (Teisha, 2013). Insulin, interferons
Not mentioned in the report is a technique called bioremediation, which uses microbes to clean up the hazardous waste. Some small natural organisms, such as bacteria, can eat, digest and gain energy from contaminants, converting them into small amounts of water or innocuous gases. Specific conditions must be present for bioremediation to be successful. Natural amendments can be added if ideal conditions are not present, or contaminated soil
With the significant increase in global human population in recent decades, the pressure for groups of people to produce enough food and energy for everyone to consume while ensuring that these resources remain sustainable and replaceable has likewise dramatically increased. While the first several challenges produced by the rise on population were met with advances in technology, notably the Green Revolution, the continued growth of the population has placed further strains on the fields of agricultural
Oil plays a immense and vital role in our society as it is organized today. Oil represents much more than just one of the main energy sources used by mankind. The oil and petroleum industry plays an extremely important role in the economy and politics of our country. Petroleum products, besides being an important energy source, serve as feedstock for several consumer goods, which in turn plays a growing and relevant role in people’s lives. But apart from all pertinent role the oil industry plays
The presence of radionuclides and heavy metals in our surroundings has become the most serious environmental concern. These contaminants or pollutants fail to degrade on their own over time and must be removed or neutralized. Microorganisms act as natural catalysts in the process of transformation of toxic metals into non-toxic ones. This is why there is an increased interest in the understanding of microbiological processes which help in remediation of these toxic wastes from the environment (Francis

little. This includes religious fasting and bioremediation. During religious fasting, there is generally little to no fresh input of nutrient. So the body must use fat reserves in the body to perform cellular respiration. The lipids stored in the body take a related metabolic pathway. Eventually the energy extracted from the fat fuels ATP synthase that makes ATP to be used by the body for energy, even though there is no input of nutrients. Bioremediation is the use of genetically modified organism
When someone is passionate about something, you can see it radiate through their smile, hear it resonate in their voice, and feel it’s energy emanate from their enthusiasm. Talking about biological topics such as protein function, DNA regulation, and cellular communication makes my heart rate jump to about 120 beats per minute and my eyes double in dilation. This partly because I always get excited when someone actually wants to listen to me talk about biology. The other part of my enthusiasm stems
are often ineffective or uneconomical when heavy metal concentration is higher than permissible concentration (less than 1 mg /L), which require a high cost when they used for heavy metals disposal from aqueous effluents. (Abbas et al., 2014). Bioremediation processes are very attractive compared to physicochemical methods like electrochemical treatment, ion exchange, precipitation, reverse osmosis, evaporation, and sorption for heavy metal removal because they require lower cost and have higher efficiency
