lab is to successfully infiltrate E. coli bacterial cells with a pARA-R plasmid that is antibiotic resistant and has the rfp gene‚ or red fluorescent protein. This can be verified if the E. coli obtains the characteristics of the plasmid when it enters. To start‚ three Petri plates containing agar are needed. On each plate there is a control group and a treatment group; the treatment group being the one with the plasmid. Before the plasmid is put with the E. coli‚ first the bacteria are “stressed

The Escherichia Coli bacterium was discovered in 1885 by bacteriologist Theodor Escherich. He found the bacteria in the human colon and showed that some strains of Escherichia Coli were responsible for infant diarrhea and gastroenteritis. The Escherichia Coli was originally named Bacterium Coli. The name was changed to honor Theodor Escherich. E coli are normally harmless and are part of the normal flora found in the lower intestines of humans and healthy cattle. Some E. coli serotypes are known

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.

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

There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics to other purposes such as knowing the exact microorganism has to be used to make certain foods. This experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by the lab instructor. The methods that
