Bioremediation Project Presented by: Alex Dunford, Holly Fontaine, Emily Hight, Whatley Ozer, Theresa Blaz Prob Scenario and Specifications Due to the the growing number of agricultural areas around the United States, these farms across the country have had an increasingly large impact on local runoff. The high concentration of phosphates and nitrates in the many water systems such as the rivers, streams, and ponds have caused many environmental problems. Different algae in

Intrinsic and Engineered Bioremediation: A review A Aarthy(14BBT0093) aarthy96@gmail.com Vishal Joshi (14BBT0097) vishu.joshi60@gmail.com Abstract: With the rise in waste production, we need methods to tackle them. The conventional methods just transfer the waste from one site to another. Bioremediation is one of the solutions for waste management which is environmental friendly, efficient and cost effective. It depends on the ability of living organisms to degrade the contaminants. Though intrinsic

of the oil. If given the ability to choose amongst the methods, I would have chosen to use both bioremediation and traditional clean up methods. I would first use bioremediation because it gets rid of majority of the contaminants and pollutants. In order to get rid of the remaining qualities of contaminants, the traditional clean up methods could be used. It would be more beneficial to use bioremediation to remove all of the pollutants that can be removed with its use first because it is healthier

However, there are a number of advantages to bioremediation, which may be employed in areas which cannot be reached easily without excavation. The foundation of bioremediation has been the natural ability of microorganisms to degrade organic compounds. Bioremediation is not a panacea but rather a natural process alternative to such methods as incineration, catalytic destruction, the use of adsorbents, and

INTRODUCTION A chemical reaction is the chemical change of atoms and molecules. They is are an essential part of daily life, and can be very useful for solving various problems. This essay discusses the use of bioremediation in oil spills, and the chemical processes involved. PROBLEM An oil spill is simply the release of liquid petroleum (also known as crude oil) into the environment. Large-scale oil spills are very problematic, as they as they can cause a multitude of short-term and long-term

The fermentation does not require external electron acceptors because the organic contaminant serves as both an electron donor and an electron acceptor. Through a series of internal microorganism-mediated electron transfers, the organic contaminant is converted into harmless compounds known as fermentation products. Examples of fermentation products are acetate, propionate, ethanol, hydrogen and carbon dioxide. Fermentation products can be biodegraded by other species of bacteria, eventually turning

Bioremediation is a waste management technique that involves the use of organisms to remove or neutralize pollutants from a contaminated site—in this case, the waters of Alaska. According to the EPA (Environmental Protection Agency), bioremediation is “treatment that uses naturally occurring organisms to break down hazardous substances into less toxic or non-toxic substances (bioremediation, Wiki). In terms of bioremediation and the oil spill, this technique consist

damaged plants. Its application in bioremediation comes from its ability to increase in number and change its macro structure in response to oil contamination. Most organisms react to metals by detoxifying them but they make sue of different methods to do the same. Psedumonas functions by utilizing carbon that it obtains from hydrocarbon compounds. Therefore crude oil, phenol, heavy metals or other hydrocarbon compounds are its source of

paragraphs for various types of plagiarism. Indicate what you think is plagiarized and why. Finally, write a concluding paragraph for the essay, without plagiarizing. Bioremediation, or the use of biological remedies for pollution reduction, is being tested as a potential solution to certain environmental catastrophes. Bioremediation has been used to treat sewage for many decades. Recently, it has been investigated as a treatment for refractory chemical wastes. State of the art knowledge on

Since the industrial revolution, crude oil has been the major source of energy which powers daily life. Crude oil otherwise known as fossil fuel, consists of a complex mixture of different molecular weight hydrocarbons and organic compounds that are explore from the earth. Crude oil is heterogeneous in nature with the main constituents being aromatic and aliphatic hydrocarbons, asphaltines and resins (Al-Gamdi, 2011). At high temperature and pressure, crude oil is formed through the pyrolysis of

combination of these methods is used for a more efficient and cost-effective treatment of a contaminated site [1]. Today, the remediation of Cr(VI)-contaminated sites is usually based on physical and chemical approaches, but bioremediation is becoming increasingly significant [10]. Bioremediation of chromium is based on the microbial reduction of Cr(VI) to the much less toxic Cr(III). Moreover, it precipitates as Cr(OH)3 (in the pH range 6-9) and thus immobilizes the chromium in the soil matrix [5]. 1.3 Scope

Basidiomycota contains the most morphologically, physiologically and biochemichally complex and evolutionarily derived members of the Kingdom Fungi, comprising some of the most popularly known fungal species, such as the gilled mushrooms and bracket fungi. They inhabit a wide range of ecological niches, performing vital ecosystem roles, particularly in global carbon cycling and as symbiotic partners with a wide range of other organisms, such as plants, animals, algae and other fungi. Specifically

Deinococcus radiodurans is an interesting obligate aerobic and polyextremophilic bacterium, harboring characteristics that allow for growth and survival under some of the world’s harshest conditions. In 1956, Arthur W. Anderson et al. discovered the bacterium while conducting food sterilization experiments at the Oregon Agricultural Experimental Station in Corvalis. After using substantial doses of gamma radiation on canned meat, the researchers found that the meat still spoiled, and D. radiodurans

denitrifying bacteria convert nitrates into nitrogen. Bacteria can cause food poisoning. If food is contaminated or not stored properly bacteria will grow and will make you very sick Some bacteria are used to combat pollution known as Bioremediation. Bioremediation is the use of microorganisms to consume and breakdown environmental pollutants. When bacteria invades the body it lowers your immune system and make the body more vulnerable to other types of viruses and

1. Introduction Bacteria have evolved several different mechanisms to enable them adapt successfully to their environment. All organisms have intrinsic genetic determinants that are expressed when challenged with different stress factors. Examples of such environmental stressors include antibiotics, chemicals, ionizing radiation, high salinity, extreme hydrostatic pressure, extreme temperatures and heavy metal stress, among others. When faced with single or multiple challenges, a series of transcriptional

It is important to isolate the bacteria having a high capacity to degrade hydrocarbon contamination to perform the bioremediation methods in contaminated areas (20). In the current study, a bacterium strain MS1 with high capacity responsible for crude oil degradation was isolated from surface sediment of Kish Island and identified as Halomonas sp. The genus Halomonas, which was initially suggested by Vreeland (21) and includes more than 20 species, are among the largest moderate halophilic bacterial

As time goes by, people are racing to develop technologies in order to help solving problems, such as building the industries and all of its machines. However the industrial itself has several drawbacks such as the industrial waste. Sludge soil that contaminated by heavy metal is one of the examples of industrial waste. Heavy metals have a negative effect on human’s health, such as mental disorder. Exploration, transportation, and exploitation of crude oil can cause marine and terrestrial oil pollution

Unlike mercury and lead, arsenic is a metalloid; and in some food source; like rice; the biggest problem. Arsenic is toxic and carcinogenic, it is highly abundant in nature with a mean availability of 5mg/kg soil within earth’s crust (Manvi Singh, 2013). One of the reason arsenic is abundant in the soil and water is because of mining of coal and other metals. Therefore arsenic contamination has a widespread reach, in regards to food consumption it not only contaminates sea-based food, but also land-based

For a substantial number of years, rotted plants, creatures and microscopic organisms have been reused into energy in many types of mixes. These mixes are rich in hydrogen and carbon and are being expelled from various underground locations and utilized as its primary wellspring of energy. There is a broadly acknowledged hypothesis that oil and petroleum products were shaped many years prior from dead plants and creatures that passed on and tumbled to the base of the seas. So, after some time, covered

protein being creating in the cell. In this specific case, the protein that makes the Aequorea victoria jellyfish fluorescent, is transferred into the bacteria. The process of transformation can be used in a variety of fields including agriculture, bioremediation, and medicine. Though this is usually beneficial, transformation can lead to bacteria developing the ability to be resistant to antibiotics by having a mutant bacteria cell that has resistance, spreading that resistance to every bacterial cell
