INTRODUCTION The rapid expansion and increasing sophistication of the chemical industries in the past century and particularly over the last thirty years has meant that there has been an increasing amount and complexity of toxic waste effluents. Even though policies and environmental efforts should continue to be directed towards applying pressure to industry to reduce toxic waste production, biotechnology presents opportunities to detoxify industrial effluents. Bacteria can be altered to produce

The Long- Term Effects of oil on ecosystems: A comparison of the Exxon Valdez and the BP oil spill The Exxon Valdez was a single hull, 987-foot super tanker built by the National Steel and Shipbuilding Company, out of San Diego, California. The Exxon Corporation commissioned this ship into service on December 11, 1986. After the March of 1989 collision with Bligh Reef, the vessel was towed to the shipyard in San Diego and repaired in June of 1989, more than 1,600 tons of steel needed

infected person dehydrated. E coli is a very common cause of food poisoning. Prokaryotes are used to solve environmental problems, while they cause illness to human. Prokaryotes are used to as to remove pollutants from air, water, and soil is bioremediation. The most familiar example is the use of prokaryote decomposers to treat human sewage. Anaerobic bacteria decompose the organic matter into sludge, while aerobic microbes do the same to liquid wastes. In the mining industry, prokaryotes can be

resistance to chemical treatments (e.g. resistance to a herbicide), or improving the nutrient profile of the crop. Examples in non-food crops include production of pharmaceutical agents, biofuels, and other industrially useful goods, as well as for bioremediation. I disagree with the use of GM (genetically modified) crops. Scientists need further research on that before using those GMOs. Scientists also need to know the long term effects of GMOs when people continue using it. It may not be studied yet

Environmental Pollution is an international journal that seeks to publish papers that report results from original, novel research that addresses significant environmental pollution issues and problems and contribute new knowledge to science. The editors welcome high quality papers where the pollutants are clearly defined and measured and can be directly related to biological, ecological, and human health effects. This includes air, water, and soil pollution and climate change. New techniques

biotechnology is the study of DNA fingerprinting which detects a unique DNA pattern to convict criminals. It also uses in paternity cases, tracking, and confirming the spread of the organisms such as tuberculosis and E.coli (Thieman & Palladino, 2013). Bioremediation is the process of using biotechnology to clean up environment pollution, which causes of industrial progress. One of the most clean-up event is the Exxon Valdez oil spill in Prince William Sound, Alaska in 1989. Aquatic Biotechnology uses aquaculture

Bacterium Research: Thiobacillus Thiobacillus are small, Gram-negative, rod-shaped cells (0.3–0.5 × 0.9–4.0 µm). Some species are motile by means of polar flagella. No resting stages known. Energy is derived by the oxidation of one or more reduced sulfur compounds, including sulfides, sulfur, thiosulfate, polythionates, and thiocyanate. Sulfate is the end product of sulfur-compound oxidation, but sulfur, sulfite, and polythionates may be accumulated by most species, sometimes transiently. All species
