Unit 7 Introduction In this piece of coursework‚ there are few amounts of ideas and experiments that I could achieved of which different products to test for my concluding idea. The type of bacteria that I am going to discuss and chosen is E-coli. I will also going to research the effectiveness of antibacterial cleaning products‚ for instance sanitizer. I will also‚ research which is the most effective product for the house hold and some other work places. Background Information What are

acknowledges a pending threat to the business operations of the restaurant‚ and becomes very insightful by observing and theorizing a possible correlation between the decline of sales of the restaurant’s beef products and the increase of reporting of E. Coli contamination at local grocery stores. It will be imperative for the ownership to take up on this research proposal‚ because if the findings result in the fact that there is a possible correlation between the reports and the decline in sales‚ the

Escherichia coli also known as E. Coli‚ is a type of bacteria which thrives in polluted water. Many people will come in contact with this type of bacteria in their lifetime. In fact‚ E. coli is normally found in the intestine of humans and animal where it plays a significant role in the digestive system. The bacteria can also be found in raw meat and uncooked vegetables as well as polluted water. Most of the strain of E. coli are harmless therefore they will not cause illness if consumed. “One of

1) TITLE (2pt): Testing antimicrobial props in soaps 2) INTRODUCTION (6 pts): In this experiment we wanted to test how effective different types of soaps against E. Coli. For this experiment we were interested in looking at antimicrobial soaps vs. non-antibiotics soaps in their effectiveness to kill E. Coli. The protocol that we used was the Kirby Bauer technique. This technique was used to test the antimicrobial properties of each soaps. (“Kirby-Bauer” 2015). 3) METHODS (6 pts): We first started

This article is about public and private swimming pools being contaminated with E. coli. Chlorine is not doing its job in sanitizing the human waste in the swimming pool. Human waste seems to refuse being sanitized. The Centers for Disease Control (CDC) concluded that the E. coli came from one major primary source; swimmers pooping in the swimming pool. Researchers say such contamination is due to swimmers not rinsing themselves off before going in the pool. Scientists say a person carries about

RESULTS AND DISCUSSION E. coli and S. aureus were tested to determine effectiveness of photodynamic inactivation with the use of methylene blue as photosensitizer and blue LED as alternative light source. Table 1 shows the resulting number of colonies for each replicate of every treatment per bacteria tested. Each of the treatments was averaged to get the mean number of colonies per treatment. All experimental setups were produced in quintuplicate‚ however only three of the five replicates were

Transformation is the genetic alteration of a cell‚ resulting from the intake of exogenous genetic material through the surrounding cell membrane. The purpose of this lab was to determine transformation of bacteria by testing the effect of P Vib plasmid of E. coli MM294‚ and how the color of the E. coli bacteria changes. In this lab‚ two small test tubes were given calcium chloride‚ E. coli MM294‚ and one of the tubes also received the plasmid P Vib. The test tubes were then placed in ice‚ heat shocked

their food intake is through meat and dairy products and it’s not a lie when people say the food industry is a bunch of shady people. Past generations have been able to eat raw beef without even considering consequences like e-coli‚ but at this point in the United States e coli is the least of our worries. It is time to stand up against the food industry and make a change for the better of our world‚ and our future generations. The United States is a country where food is being mass-produced. We
