    We are part of a society that has become obsessed with removing all forms of bacteria from our lives. We use anti-bacterial soap, wipes, cleaners, and even anti-bacterial gels to put directly on our hands. However, bacteria is a very important part of our lives. Some bacteria can control pollution, degrade plastics, help with targeting and curing cancer tumors, as well many other useful applications in out lives. One of the common uses for microorganisms in the environment is in bio-remediation

    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

    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

    Oil Spills 1. a. What are some chemical methods that are used to clean up an oil spill? There are many different chemical methods used to clean up oil spills. Dispersants are used to break down the oil and speed up its natural decomposition. There are three different types of dispersants. The first type is a hydrocarbon based solvent. These dispersants are sprayed onto the affected area to dilute the oil contamination. The second type of dispersants are made of alcohol or glycol solvent. These

    Phytoremediation: Green Technology for the Future Phytoremediation is the process by which plants and trees are used to remove or stabilize hazardous pollutants that exist in soil, sediments, surface water or groundwater. The EPA (environmental protection agency) estimates that more than 30,000 sites in the U.S. are in need of environmental treatment, and a great number of these sites are contaminated with highly toxic metals. Abandoned or under-used commercial and industrial facilities, termed

    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

    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

    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

    All soils and water contain various metals that vary in concentrations. Mg is a macronutrient and is essential for enzymatic activities relating to photosynthesis. A substantial amount of Mg is found in plant tissue, hence the term macronutrient (Manahan, 2010). Metals, such as Fe, Mn, Cu, Zn, and Ni are essential micronutrients for many living organisms (Cempel and Nikel, 2006; Göhre and Paszkowski, 2006; Manousaki and Kalogerakis, 2011; Kalogeropoulos et al., 2012), however at high concentrations

    Many recent studies using showed that microbial communities in heavily contaminated soils and sediments have the capability of PAHs biodegradation without a lag period as 14C-labelled PAHs were biotransformed into 14CO2. Microbial communities in contaminated soils and sediments with low levels of hydrocarbons can easily be adapted for rapid anaerobic PAH biotransformation once they are exposed to PAHs contamination. The extent of PAHs biotransformation under anaerobic conditions is directly proportional

    Introduction Soil contamination is a worldwide environmental problem. It is caused by either solid or liquid hazardous substances, such as toxic trace metal, mixing with the naturally occurring soil. Contaminated areas are often those with mining activities or agricultural land affected by the use of metal-containing fertilizers. Mining and mineral processing in particular generate large quantity of by-product mine wastes. These are collected in mine waste piles and tailings, and may cause severe

    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

Richness and Shannon diversity index of Glomus was found significantly higher in site 1 compared to other two sites (Fig. 4). The sequence of dominant bands obtained from DGGE analysis and their closest AMF species match from genbank are presented in Table 2. All three sites were dominated by uncultured Glomus and G. mosseae. In addition, site 2 and site 3 were dominated by G. intraradices. DGGE analysis and

    Factors Affecting Petroleum Biodegradation Rates Favorable conditions for microbial growth and degradation of the pollutants require knowledge on the different factors affecting the rates of biodegradation. At optimal conditions, maximum biodegradation occurs. Among these factors are the physical and chemical characteristics of the contaminated material, and also the characteristics of the microorganisms to be used. Chemical Composition, Molecular Weight, and Solubility Hydrocarbon biodegradation

    Bioremediation & Green Infrastructure by Stephanie Marandi The effects of intensive human activity have taken a heavy toll on Jamaica Bay’s ecosystem and have threatened the area’s future productivity. Excessive physical alteration of the shoreline and bay bottom, together with widespread pollution have affected the hydrology and water quality of the bay, leading to an unfortunate and accelerating loss of intertidal wetlands since the mid-1970s.

    Introduction: “Bioremediation is the process of using organisms to neutralize or remove contamination from waste” (Conserve Energy Future, 2017). It is an alternative way to manage or degrade materials, being eco-friendly, and much more cost effective compared to traditional techniques such as incineration. (Philp, 2015). “Bioremediation is an attractive and successful cleaning technique for a polluted environment.” It has been used at a number of international sites, including Europe and South
