Plasmids And E. Coli Growth

Improved Essays
After analyzing the results obtained, one can state that the data provided gives us enough evidence to support that the plasmids without any ampicillin had the highest levels of E.coli growth, while the plasmids with ampicillin had the lowest levels of E.coli growth. This represents that there is enough evidence to reject the null hypothesis, stating how there is no correlation between the plasmids and the ampicillin present. There’s enough evidence to support the alternative hypothesis, which states that there is a correlation between the plasmids and the ampicillin present in the bacteria. The results indicated in Figure 9.1, represent how in the six agar plates obtained, three of them had ampicillin, while the other three had no ampicillin. …show more content…
In the agar plates containing both pUC18 and lux various colonies were observed. This showed the effect of the plasmid on E.coli survival in an antibiotic environment. Each colony was formed by the survival and reproduction of a single cell (Singer 2014). As the cells in both agar plates continued to replicate, so did the plasmids, providing every cell with the gene necessary to survive in the same environment (Alberte et al., 2012). The plates containing no plasmids showed no colonial growth; all E.coli cells were killed by the antibiotic before they were able to reproduce. This made it possible to tag the cells, making it clear that only those cells that replicated had been transformed (Singer 2014). The three plates containing no ampicillin, showed stable patchy growth leaning towards lawn growth. If the plates had been left at their optimal temperature for about a day longer, lawn growth was highly likely to be

    Escherichia coli DH5훂 is the third species being studied. Since E. coli bacteria are considered model organisms, they make perfect study subjects. This particular strain of E. coli is not considered a pathogen. It was made especially for laboratory study. It’s main use has been mostly for cloning.…

    coli is considered a mesophile, meaning it grows at moderate temperatures, between 20°C and 40°C, with its optimal growth temperature being 37°C (Piispanen, 2017, Fall Lecture). The results demonstrates that 37°C is the most optimal temperature for growth, as this plate had the highest number of colonies present. However, to support this statement of E. coli being a mesophile, there would had to have been growth on the plate incubated at 23°C. To clarify these findings further and investigate why there was no growth on the 23°C, the experiment could be performed an additional time. However, the sample could be diluted more, using a dilution other than 10-6, such as 10-8.…

This is not the first time that a person had been infected with E. coli, but it is the first time that an outbreak became widely known and as far spread. Jack in the Box fast food chain was accredited with the blame for this first big E. coli outbreak. Ever since this first large infection with Escherichia coli the world has been on edge, not wanting another major outbreak.…

    In conclusion, the hypothesis the SPC method of establishing a growth curve and determining the number of bacteria colonies present in a culture would be more accurate than the OD spectrophotometer could be true in more experienced cases where there is less chance of human error because the Spec 20 cannot differentiate viable cells and dead cells. The Standard plate count method, considering if the inoculations and dilutions are done correctly, and the environmental conditions are most efficient for growth of E. coli, then this method should be better for establishing an accurate growth…

    It is also important to get information about changes in population, and characteristics of the cases involved. Our method of determining if the cases were related was by performing an DNA fingerprinting by Pulsed field gel electrophoresis. In DNA fingerprinting, bacteria is cut and the pieces are separated by placing in jelly-like substance. Smaller pieces move through the gel quicker than larger pieces which results in separation of DNA into distinct bands. If the DNA is different it will result in a different banding patterns but based on figure one in appendix E five out of the seven isolates were indistinguishable from each other.…

    E. coli Genomic DNA Isolation and Quantitation Introduction In this experiment, the genomic DNA of E. coli cells were isolated, purified, and quantified. To achieve this, E. coli cells were lysed, purified from impurities and Methods E. coli cells were first centrifuged in order to separate the cell pellet from the supernatant. Cell pellets were resuspended in saline-EDTA, which weakens bacterial membranes and chelates metal ions. Since E. coli has three layers (outer membrane, peptidoglycan layer, and the inner membrane) saline-EDTA helps break the outer membrane by removing the cations that link the phosphate groups in the ends of lipopolysaccharides.…

    Colonial growth is the key to discovering whether there was a successful transformation in the bacterium 's cells. If there is colonial growth of E. coli in an ampicillin environment then the plasmids triumphantly transformed the cell and as a result were able to create either the enzyme beta-lactamase, for the pUC18 transformed cells, or the enzyme luciferase, for the lux transformed cells, which would counteract the effect of ampicillin on the cell wall of the bacteria. There were many errors in this experiment. Only two of the agar plates actually developed properly, one of them was the ampicillin agar plate with no plasmid (Fig 1: top left) because there was no growth seen. This was the expected result because since ampicillin kills the bacteria, the E. coli cells should not have been able to survive in the environment…

However, different types of bacteria grow in different places depending on the environmental conditions and the required factors for growth for the specific bacteria. Also, I learned is the impact an error in the procedure can have. I think there were some errors in our environmental sampling lab.…

    Discovered in a human colon in 1855 by German bacteriologist Theodor Escherich, E. coli is “the most prevalent infecting organism in the family of gram-negative bacteria known as enterobacteriaceae”, according to about-ecoli.com. Scientifically, it was previously known as Bacterium coli, it was later changed to Escherichia coli in honour of its discoverer [1]. E. Coli lives in the human and animal intestines, even though many differing types are harmless, e. coli is a source of food poisoning. The most frequent way a being may get e. coli is from contaminated foods, such as unpasteurized (raw) mild and juice, drinking untreated or swimming in contaminated waters, raw fruits and vegetables (sprouts for example), and especially undercooked ground…

    One of the key questions asked within the field of evolutionary developmental biology (ev-devo) today is that of how mutation and selection work together to bring about evolutionary changes. Originally thought that the two mechanisms works independently of each other to bring about change through natural selection operating to the extent that it can and that mutations account for anything that selection doesn’t (Livnat. A 2013), this view is now been believed to be incorrect. By exploring the two essential key evolutionary mechanisms, mutation and natural selection, a deeper understanding of how evolution has shaped the world around us can be achieved. Through the study of evo-devo, many examples of how mutations and natural selection work together to achieve evolutionary change can be found.…

    The organism proved to be negative in citrate utilization, narrowing done the options to just three unknowns. The final tests needed to decide the identity of the unknown were the lactose and urease tests. A positive lactose resulted, along with a negative urease test. These two final tests, along with the tests before, led us to the conclusion of the unknown identifying as Escherichia coli. Very often throughout the testing and identification process of an unknown, false negatives or false positives occur.…
