n of marine oil is time-consuming as a result extensive damage can occur to the marine organisms and indirectly upon humans when they consume such organisms. This time lag is effectively being reduced through processes such as bioremediation through which the available bacterial population is altered or increased by addition of exogenous microbes and stimulation of indigenous population (Bioremediation methods for Oil Spills, n.d). Processes such as eutrophication have lead to increased production of organic matter which in turn results in anaerobic conditions due to oxygen uptake by heterotrophic organisms. Under such conditions mineralization of organic matter by processes such as sulphate reduction by marine-sulphate reducing bacteria can play a vital role. These anaerobic bacteria utilize sulphate as the final electron acceptor during their respiration which releases hydrogen sulphide into the environment. A number of enzymes are involved in this process and the large amounts of hydrogen sulphide released are vital from an ecological and economic viewpoint. Studies have also revealed a direct relationship between the number sulphate reducing bacteria and the amount of hydrogen sulphide released (Mudryk, Podgórska & Bolalek, 2000). The identification of microbes which degrade crude oil has been done by serial dilution of sea water samples and plating them on mineral media followed by spraying a layer of crude oil on the agar plate. The bacterial isolates which appear after an incubation period are then screened by using overlay techniques (Sakalle & Rajkumar, 2009). In another techniques beach simulation tanks oil-polluted cobble stones collected from a contaminated beach were put into tanks which were filled with sea water. The gravel was then inoculated into enrichment cultures followed by broth and agar culture (Cerniglia & Perry, 2007). The DNA was then isolated from pure cultures and nucleotide sequencing of 16S rDNA was carried out which was then used
The role of microorganisms in degradation of marine oil spills is being constantly investigated as the fate of petroleum compounds in marine environment depends on their transformation or degradation by microbes. More than hundred known species of bacteria and fungi play a role…
Although these questions are plain and general but their answers are way too difficult and important. They have confused many a man. A philosophical question is concerned with comparing things and asks about ‘goods and bads’ of the choices. But science generally propounds questions which are concerned with how things work.
There are many other clues that people use to guess ethnicity. If I do not get a chance of asking the other person where he is from, the first thing I would consider is his language and the accent he is talking in. Different regions in a country have different accents and these help in guessing a person’s background.
The book narrates about the struggles that exist between the indigenous social movements, the multinational energy company and the Ecuadoran state (Sawyer, 2004: 2). It is based on anthropological research in the Ecuadorian Amazon in the 1990s. Suzanna Sawyer reports how a grassroots organization, the Organization of Indigenous Peoples of Pastaza (OPIP), confronted multinational companies that wanted to drill for oil in their region.
The passage provides some explanation about the place of a claim or thesis within the body of the argument. The centrality of a claim is paramount in the process of developing an argument towards a logical conclusion.
However, the focus remains under the parameters of problems related to oil supply and provides little solution and relatively low amount of analytical approach.
It can be stated that this article is chiefly a 'problem indicating' text and in doing so the writer provides a wide range of data with supporting facts and figures but little is presented in terms of analysis of those data, facts and figures.
These changes have shed light to them as their status as rent states, which pertains to their significance as oil producers makes them rich by developed countries standard. The changes that are currently
