Those intermediates are then converted into hydrogen gas or acetate through means of acetogenisis, and with the final methanogenisis phase, converted to methane to be used as biogas, with a 60 to 70% methane availability in the gas, making it useful for energy production (Angenent et al., 2004).. When considering resource recovery and renewable energy production to reach a sustainable management of organic waste, anaerobic digestion plays an essential role towards reaching that goal (Kapdi et al., 2005).. Anaerobic digestion is a useful wastewater treatment method as it has economic value in addition to its environmental waste treating potential (Appels et al.,

    Hydraulic fracturing, or fracking, is a method used access the natural gas that exist in the shale formation layer which is around 6000 feet below ground, in a cost effective way. After fracking horizontally, they blast the water mixed with salt and chemicals into the bedrock. Due to high level of pressure shale is cracked and the gas bubble is released. Natural gas flows back to the well head at the surface. This method of gas extraction has never previously been used on such a wide scale as its being used now.

    In the mid-1900s, scientists developed new varieties of plants such as wheat and other grains that had higher yields and greater resistance to pests, diseases and drought. This was considered a long-range response to the hunger, environmental damage and global epidemics that many countries worldwide were faced with as part of World War 2. This is what was known as the Green Revolution. The Green Revolution, though it helped with a greater grain production, it also resulted in changes concerning role women within the workforce, a negative effect of the environment and traditional values specifically In Punjab India and a defined difference between the rich and the poor.

    We got negative for indole (no production of indole, pyruvic acid and ammonia), negative for Methyl Red (our bacteria does not perform mixed-acid fermentation when supplied glucose), negative for Voges-Proskauer (no fermentation of glucose in order to produce 2,3-Butanediol-Butanediol fermentation), but positive for Citrate utilization, which means our bacteria uses citrate as a sole carbon source and energy. Something interesting here is that according to the lab textbook organism that degrade citrate must also use ammonium salts, and in the process, they produce ammonia that causes the medium to become alkaline (under this condition the medium turns to deep Prussian blue, indicating the utilization of citrate). The genus Alcaligenes is well known for being alkali-producing

    The decomposition of NaHCO3 is an example of Prevention within Green Chemistry principles because all solid waste in this experiment is collected and used again. The only gaseous wastes generated by the reaction in the experiment are carbon dioxide and water, which are benign (Lab 3). The decomposition reaction of NaHCO3, generates virtually no waste, therefore less hazardous chemical syntheses. The byproducts of the reaction are gaseous CO2 and H2O which possess little or no toxicity to human health and the environment, because of the amounts released in this experiment. (Lab 3).

    Then, tests are performed to determine if the products of aerobic and anaerobic respiration are present in the flasks. The citric acid cycle consists of a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy in the form of ATP (Biology). The tests detect the presence of carbon dioxide and ethanol. Carbon dioxide should be present irrespective of the type of respiration taking place, but ethanol is present only if fermentation has occurred. Another factor that can indicate whether fermentation occurred or cellular respiration occurred is the amount of glucose utilized during incubation.

    They can also act as a final electron acceptor. Many bacteria can be differentiated and are identified by their capacity to reduce nitrates to nitrites. Most of the bacteria belonging to the family Enterobacteriaceae reduce nitrates [165]. OF test is used to differentiate those organisms that utilize carbohydrates aerobically (Oxidation) such as P. aeruginosa, from those that utilize carbohydrates anaerobically (Fermentation) such as members of the Enterobacteriaaceae. The OF medium contains peptone, test carbohydrate and bromothymol blue as indicator.

    Pollution is the introduction or release of substances or energy that decrease the quality of the marine environment. Many pollutants are toxic of harmful to marine life (Castro and Huber, 2010). South Africa is known around the world for being one of the most diverse marine environment in the world, with 83% of the known fish families residing in South Africa (Van der Elst, 2007). There are also many marine species that are endemic to South Africa, which means they are only found in South Africa. Almost 30% of the South African population lives on the coastline (Taljaard et al. 2006), which has led to the urbanization of the coastlines and which then led to the industrialization of these areas.

  • Non Renewable Resources Essay

    2.1 INTRODUCTION Non-Renewable Resources are resources that have the potential to be used up due to consumption or overuse, they have production, development or replenishment rate that cannot match up with the depletion rate. In short these are resources that can be finished, output exceeds input, and they are infinite. Non-Renewable resources vary from non-renewable fossil fuels like coal, natural gas and oil, non-renewable alternative energy sources like nuclear energy and deep-earth geo-thermal energy, soil, and minerals (Botkin & Keller, 2012). These non-renewable resources range from a few years, up to thousands of years to replenish. The local as well as global challenge, is that most non-renewable resources are directly exploited by humans and their existence is widely threatened were usage

    Green growth and green economy have been subject to various definitions but those currently being used by international organizations have a lot in common. Greening growth (GG) and moving towards a greener economy (GE) is complex and multidimensional. Green growth is a matter of both economic policy and sustainable development policy. It tackles two key imperatives together: the continued inclusive economic growth needed by developing countries to reduce poverty and improve wellbeing; and improved environmental management needed to tackle resource scarcities and climate change. The concept of green economy rests on the economy, the environment and the social pillars of sustainable development.

    The first method is broth culture. In broth culture, Escherichia coli are grown in a liquid medium. It is shown that the nutrient broth appeared to have sediment. This shows that Escherichia coli carries out anaerobic and aerobic respiration as it can survive anywhere in the broth. The second method is agar slope culture where Escherichia coli are grown on a slant agar in a test tube.
