    Escherichia Coli

    • 1833 Words
    • 8 Pages

    Objective I. To learn how to inoculate the nutrient broth properly in preventing contamination to the nutrient broth and the culture Escherichia Coli. This is done by sterilized the loop and sterilized the neck of the tub with heat from before use and before put the cape on. II. To learn how to do a simple streak of an E. coli culture on a nutrient agar plate with one stroke from start to end like a “Z”. III. To learn how to do a complex streak where we grow E. coli culture on the nutrient agar plate for differential the isolate colonies presence. IV. To learn how to know whether the culture is a selective or differential media. The culture bacteria that will be using are E. coli, Bacillus subtilis, staphylococcus aureus and Proteus vulgaris. V. To learn how to find the extracellular enzyme production by bacteria. The culture bacteria that will be using are E. coli, Bacillus subtilis, and staphylococcus aureus. Result i. The two…

    • 5 Pages

    The spectrophotometer analysis of Escherichia coli growth during heat application The purpose of this experiment is to determine the rate of Escherichia coli (E. coli) growth over 100 minutes in a liquid growth medium (control), and to determine the rate of E. coli growth over 100 minutes in a heated liquid growth medium. The prediction is that the control E. coli culture will grow at a faster rate exponentially over 100 minutes than the experimental bacteria culture. Consequently due to heat…

    Classification Escherichia coli is a bacterium that is mostly found in humans and other animals. It is a unicellular micro-organism, making its Domain and Kingdom Bacteria. E. coli’s Phylum is Proteobacteria because it is a gram-negative bacterium. It is also in the Phylum Proteobacteria because of the lipopolysaccharides that protect the cell membrane. E. coli is a facultative anaerobic G- bacterium, making its Class Gamma Proteobacteria. Because of its rod-shape, E. coli’s Order is…

    Escherichia coli is a gram negative bacteria with pathogenic potential to both humans and animals causing three general clinical syndromes: (1) enteric/diarrhoeal disease, (2) urinary tract infections (UTIs) and (3) sepsis/meningitis (Kaper et al., 2004). However, this bacteria uses different virulence factors to cause the above-mentioned clinical syndromes (Croxen and Finlay, 2010; Kaper et al., 2004). The E. coli producing pore forming toxin α-hemolysin causing bacteraemia/sepsis causes…

    Escherichia coli and Me The disease/infection that I have chosen is the urinary tract infection, commonly known as the UTI. Depending on where the infection occurs, there are two specific names. If the infection occurs in the lower part, like in your bladder, it is called Cystitis. If the infection travels up towards your kidneys, it is called Pyelonephritis (Umm/Health). The microbe that causes this infection is Escherichia coli, more commonly known as E. coli. It is found commonly in…

    Unknown Organism Report I have identified my Unknown Organism #1 as Escherichia coli, or E. coli. My Unknown Organism is an anaerobic gram-negative, unicellular eubacteria. It belongs to the genus Escherichia, which is named after Theodor Escherich, a German pediatrician. E. coli is usually found in the colon of mammals, explaining the name “coli” meaning from the colon. It’s classified in the order of enterobacteriales, and the family of enterobacteriaceae. It is the most abundant bacteria in…

    Let’s start the introduction by talking about our main target, Escherichia coli or how it is mostly unknown, E.coli, are a diverse and large group of bacteria found food, the environment, and in the intestinal tracts of humans and animals were it normally inhabits and it can also cause infection in other parts of the body, especially the urinary tract. Its name was given by a German physician called Theodor Escherich and it is the most common member of the genus Escherichia. E.coli is “a…

    active and visible. The arabinose C gene also present with the GFP recognizes and binds to arabinose so that they gene may produce the glow. A common bacteria used in this process is Escherichia coli, better known as E. coli. It is a small, single-celled bacterium with a rapid reproduction rate, making it ideal to use in transformations since the effects will be seen much faster than with other hosts. When the bacterium receives the genes from the plasmids, it provides better traits for…
