Water is one of Earth’s most precious resource. All living things need water. In this report we will be discussing which water is safe for drinking, how the quality of water is tested, where it is stored and collected, how it is purified and using an alternative supply to tap water. Safe water is water that will not harm you if you come in contact with it. This type of water is free from harmful micro-organisms and substances. This water would also have had to be tested and met certain…

There has been an increased interest and knowledge in relation to privacy rights and issues. The reason for this is that they are a fundamental right which ensures the personhood of individuals by allowing them to control who has access to personal information about them. Privacy issues are also of importance because it helps individuals avoid unwanted intrusions in their personal dealings. Consequently, for the reason that privacy is such a complex concept, there have been ongoing concerns and…

In Gram negative bacteria cadmium is targeted on DsbA gene in the periplasm. DsbA gene is responsible for the formation of disulfide. Cadmium resistance in some gram-positive bacteria was also found to be mediated by CadA-like proteins (Liu et al., 1997). In S. cerevisiae…

human rights and how each one interrelates. Then I will make the case that human rights isn’t a western concept on the basis that rights are universal irrespective of culture. Human rights come under three main categories; negative rights, positive rights and group rights. Negative rights are characterized as civil, political rights or ‘first generation rights.’ They are framed as ‘freedom forms’ or ‘freedoms…

the slide for 30 seconds. 4. Observe what happens to the bacteria, and check the results against what is known to happen to certain kinds of bacteria in the presence of KOH, Gram positive will turn watery and will have a purple color, while Gram negative will be mucosal and turn pink. Prepping Test Tube Bacterial Specimens for Spectrophotometer Use/Using a Spectrophotometer Procedure: 1. Blank the spectrophotometer. 2. Get a small cuvette. 3. Use a pipette to add the mixture you want to use in…

Burkholderia pseudomallei also called as pseudomonas pseudomallei is an intracellular gram negative bipolar staining aerobic motile shaped rod with a safety pin appearance when seen microscopically measuring 25 micro metre in length and 0.4 -0.8 micro metre in diameter . It is capable of self population using flagella. In vitro , it requires a temperature of 40 degree and grows in an acidic environment fermenting glucose and galactose . It produces both exotoxin and endotoxins. It causes…

Biotechnology and probiotic GOS (Galacto-oligo-saccharides) INTRODUCTION What are Prebiotics? Prebiotics are commonly defined as non- digestible polysaccharides and oligosaccharides. These prebiotics enhance the growth of beneficial bacteria like lactic acid bacteria in intestinal tract and also exert antagonistic property against some other species like salmonella sp. or E. coli. Some scientist also defined other properties of prebiotics; which includes resistance to gastric activity,…

around the disc were measured and sensitivity and resistance of strains were determined and then results were compared with CLSI standard table.20 In each experiment, a disc containing the solvent dimethyl sulfoxide (DMSO) 10% was determined as a negative control and a disc containing Vancomaycin 30 μg/disc and Ciprofloxacin 5 μg/disc standard positive control was used as an antibiotic. The tests were repeated three times and the results were presented in the…

difference between gram negative and gram positive bacterium. This is important when doing gram staining experiments. It also looks at the importance of microbiology. DIFFERENCES OF GRAM NEGATIVE AND GRAM POSITIVE BACTERIUM There are notable differences between the gram negative and gram positive bacterium. Gram negative bacterium is surrounded by a thin peptidoglycan cell wall while Gram positive has a thick layer of peptidoglycan. The peptidoglycan around the gram negative is about 8-10 mm…

trillion of US dollars a year (Pugh). We will also have to use the negative income tax system. A negative income tax will tax the first $35,000 of additional income by 50%. People that are making an additional $35,000, will have an offset in paying taxes and will not be affected by the program (Pugh). Based on the income levels of the 2010 census, providing $17,500 to citizens will only cost the government $1.9 trillion dollars with the negative income tax in effect ("Annual Social and Economic…
