2. Introduction
In the recent years, wastewater treatment has been a matter of major concern due to increased demand of water for its varied uses. Water is a universal solvent and is vital in the transportation of a range of molecules in an organism and in the ecosystem however, it is also known to be a carrier of pathogens (Sayed et al.). Usage of clean water has significant roles in domestic, industrial, agricultural and pharmaceutical industries hence it is detrimental that the water is free of microorganisms and does not spread diseases. Water is in continuous circulation and hence microorganisms can enter it through organic wastes, soil, dead plants etc. (Brooke et al.). It is found that 80% of the diseases in developing nations such as

(Gupta G. et al.). The wastewater undergoes treatment in water treatment plants before it is released into the environment as per laws and regulations established by the government that allows the release of the water into natural water bodies only after it has achieved the minimum levels of all the parameters. It is vital that the treatment systems are effective since the treated wastewater will be under continuous circulation in the water cycle once they enter natural water bodies (Gupta V. et …show more content…
Degradation of AF would release several beneficial biomolecules in simpler forms that could potentially have antibacterial activity against clinical pathogens and MDROs (Ramani et al.). Antibacterial strategies against MDROs target specific intermediates in a metabolic pathway and interfere with the process in order to stop the pathway and hence limit the effect of the pathogenic cell. This could be bactericidal or bacteriostatic through modes of action such as inhibition of cell wall synthesis, cell membrane synthesis, protein synthesis, nucleic acid synthesis and secondary metabolite synthesis (Gupta G. et
PHAR 100 Assignment 3 1. Antibiotics are a form of medicine that seek out and destroy the bacteria that make us feel sick. Antibiotics work great against bacteria, however they don’t work against viruses. Penicillin was the first antibiotic to be discovered by Alexander Fleming, and it was first used to treat infections. Essentially, these powerful medicines fight bacterial infections, and have the potential to save lives.
The lipid A has phosphoethanolamine added to it, which in turn, inhibits the bacteria from any attachment. Q3E: What is the origin of the mcr-1 gene, and what evidence do the authors use to support this
Water from the Nile River is immensely toxic or unhealthy, but when but through cleaning systems like a filter can change that. The very scarce but clean water can provide the proper nutrients to defeat and prevent waterborne
The Houston Water Quality: Is It Really Up to your Standards? According to Forbes Magazine Houston, Texas is known for being one of the dirtiest cities within the United States. When I was conducting research on the city’s water quality, I was surprised to learn how well the city really does take care of their water supply. Contradictory to what I first thought, Houston actually has average or normal amounts of contaminates; their scores were all passing for pollutes found in their drinking water and in fact is one of the best water supplies in the Unites States.. Overall the city also seems to care more about their water safety than what I assumed too, given “providing safe and reliable drinking water is their highest priority.
In addition, the bacteria need arabinose that help activate the protein that allows to glow green in the transformed bacteria cells. To let
Staphylococcus Aureus belongs to the extremely common bacteria of microflora of the skin and mucous membranes of the humans. These pathogens cause many infections, including superficial and deep purulent infections, poisoning, urinary tract infection etc. In the US, staphylococcus bacteria are supposed to be the leading cause of sepsis, postoperative wound and prosthesis infections. In addition, staphylococcus belongs to one of the leading causes of bacterial food poisoning. Staphylococcus Aureus is one of the most dangerous human pathogen.
aureus microbe problematic is because it is the leading cause of nosocomial or hospital-acquired infections by gram-positive bacteria and is notoriously resistant to penicillin and many other commonly used antibiotics. It was actually recently reported that a strain of S. aureus is resistant to every known antibiotic in clinical usage. The emergence of antibiotic resistance strains of S. aureus, such as methicillin resistant staph aureus (MRSA), is becoming a greater problem. Since S. aureus has become resistant to most of the beta-lactam antibiotics, vancomycin, a glycopeptide antibiotic, is used to fight MRSA. However, there are now strains of S. aureus that are resistant to vancomycin, such as vancomycin intermediate staph aureus (VISA) and vancomycin resistant staph aureus (VRSA).
Wasteland is a documentary by Lucy Walker that depicts the lives of selected garbage pickers in Jardim Gramacho – a massive dumpsite found in the outskirts of Rio de Janeiro. The film is about Vik Muniz’s 2-year journey back to his home country seeking to give back to an impoverished community through making images out of an unusual material – trash. The film featured 7 garbage pickers from the landfill, and each has a story that brought them to their current places. One unique thing about the whole creative process is that the pickers themselves became part of it. Vik imagined that as they work on their own and each other’s images, the pickers will not only show themselves to a broader world that is for now comfortably oblivious of their existence, but also see themselves differently (Fuchs, 2010).
This is launched to enhance the understanding of the role of Microbiome in the ecology of humans and using the concerned knowledge in the development of therapies for various illnesses (About MGH, nd, News Releases). The department of chemistry and biological engineering, and MIT institute of medical engineering and science are involved in collaboration with MGH clinical medicine. This new partnership will follow the one that was implemented among MIT, Ragon Institute of MGH and Harvard, which started in 2009 and worked on developing effective vaccine against AIDS as a part of their study on the role of immune system in human disease (MIT News, Oct. 15, 2014). This new partnership between MIT and MGH has offered $3 million to a two-year period research project dealing with the problems in diagnostics, autoimmune and infectious diseases and in

Experiment 3: Cell Viability Testing and Counting with Trypan Blue Exclusion Method Anna Coretta R. Santos I. Introduction Cell viability assay plays a crucial role is in the cells of the cell culture. This assay can be used to identify the relationship of cell count from the cell’s behavior (Stoddart 2011). This test help researchers to determine the number of viable and non-viable cells in a cell culture. This assay helps in estimating the cell count of a cell culture and to determine if there is sufficient amount of viable cells in the cell culture that a person will use for future research (Riss et al. 2013).
Water can no longer continue to stay unprotected, it is simply too important. Today most countries have laws aimed at safeguarding water quality and controlling water abstractions (Groenfeldt, 2013). In 2010, a new human right to ‘safe water and sanitation’ was recognized by the United Nations and implemented effective immediately. Water not only feeds the human body, but also the earth. Without water, nothing can grow.
LITERATURE REVIEW What is water pollution? As the country is becoming more and more populated, the demands for social services have increased significantly. This has led to an increase of the pollution in many developing towns such as Ga-kgapane. The most disturbing and problematic forms of pollution in Ga-kgapane is the pollution of the natural streams. Water pollution is when there is a build of one or more substances in water to such an extent that it causes problems for animals or plants.
S. aureus is a non-motile facultative anaerobic bacteria. This bacteria can survive long periods in the environment; so it is readily transmissible. S. aureus causes a number of medical infections and is the leading cause of wound infections. It is an opportunistic bacteria, and infects any population. It favors the skin, since it is part of the normal flora.
Water is the most important component found on the surface of the earth because it is source of life for living creatures. However, water pollution has become a global concern. Water pollution can have several forms from diverse sources. It is expected that there will be a lack of clean water in next few decades due to pollution. Nile river water in Egypt is the focus of attention of many studies due to many reasons.
