  • Manipulation of Bacteria Essay

    3385 Words  | 14 Pages

    MANIPULATION OF BACTERIA INTRODUCTION: In this experiment that we performed, there were many methods that were used to help us manipulate and identify the bacteria E.coli on a MacConkey agar plate. The first part of the experiment involved the methods of manipulating, identifying and counting the bacteria and the second part was to find out whether the bacteria E.coli was the only type found in the given area by gram staining. E.coli was the chosen bacteria for this type of experiment. It is

  • The Effect of Heat and Growth on the Survival of Bacteria

    1485 Words  | 6 Pages

    Aims The purpose of the two experiments was to determine the fundamental effects that temperature has on the growth and survival of bacteria. During the first experiment five different bacterial broth cultures of Escherichia coli, Pseudomonas fluorescens, Enterococcus faecalis, Bacillus subtilis and Bacillus stearothermophilus were individually incubated at temperatures of 5, 25, 37, 45 and 55°C for one week in an aim to distinguish the effect temperature has on growth and survival of the five different

  • Characteristics And Differences: Archaea Vs. Bacteria

    760 Words  | 4 Pages

    Archaea vs. Bacteria When I first got the assignment, I had little knowledge what archaea and bacteria are. But throughout the research, I learned about their characteristics, structure, differences and the way they exist. Both of them hugely impact our life, and are able to think, communicate with each other and control your mind (in a sense that there is intelligence in the way they operate and function). Throughout this paper, I will try to give a brief profile of these two microorganisms

  • The Evolution of Antibiotic Resistant Bacteria Essay

    1412 Words  | 6 Pages

    The Evolution of Antibiotic Resistant Bacteria Since antibiotics, such as penicillin, became widely available in the 1940s, they have been called miracle drugs. They have been able to eliminate bacteria without significantly harming the other cells of the host. Now with each passing year, bacteria that are immune to antibiotics have become more and more common. This turn of events presents us with an alarming problem. Strains of bacteria that are resistant to all prescribed antibiotics are

  • The Use Of Bacteria For Recombinant Protein Production

    1283 Words  | 6 Pages

    plant genome, the bacterium basically reprograms the plant cells to grow into a tumor and produce an exceptional food source for the bacteria. The opines are amino acid derivatives used by the bacterium as a source of carbon and energy. Bacteria play major role on production of proteins especially for proteins that are required to be synthesised in glycosylated, bacteria have outstanding appearance system and also their relative simplicity biologically. Bacterial processes also be likely to be cheaper

  • Clorox Is Very Effective on Bacteria Essay

    758 Words  | 4 Pages

    Throughout most of history people did not believe in the existence of bacteria. These tiny organisms that can cause sickness were myth to the people in Europe during the 1400s . Plague and disease were common everyday things in the dark age. It is now known that the cause of those prevalent plagues were bacteria.According to Infection control today "Plague claimed an estimated 30 percent to 50 percent of Europe's 14th century population" ;this is means that half the population perished due to diseases

  • Investigation Of An Unknown Bacteria

    1674 Words  | 7 Pages

    identification of an unknown bacteria. This bacteria was causing a urinary tract infection on a patient. A sample of the bacteria causing the infection was received and analyzed. The first step was to isolate the bacteria to insure that sample was free of contamination. A MAC plate, a PEA plate, along with a Nutrient agar plate where used to produce pure colonies by using the quadrant streak method on each plate. After a 24 hour incubation period the colonies where isolated. The bacteria collected was inoculated

  • The Characteristics Of The Unknown Bacteria

    1300 Words  | 6 Pages

    Results The first result of importance was the result of the Gram stain. The observations of the unknown bacteria from the slant culture after Gram staining showed that the unknown bacteria were Gram negative bacilli (Image 1). After determining the unknown bacteria was Gram negative, an oxidase test was conducted on a sample from the slant culture. The cotton swap with the sample of bacteria did not change color when the oxidase reagent was applied, thus providing a negative result. With a negative

  • Biology : The Unknown Bacteria

    964 Words  | 4 Pages

    the skills and test that are taught and learned in microbiology were applied into learning what the unknown bacteria culture was. There were multiple procedures and test done in order to gain all the information needed to determine which bacteria was given. In order to find what the bacteria was the first step was finding the right environment and temperature that would allow the bacteria to thrive and grow. Determining this is one of the most important steps in being able to obtain conclusive results

  • The Role of Agarase in Agar-Degrading Bacteria

    1848 Words  | 8 Pages

    The Role of Agarase in Agar-Degrading Bacteria Abstract Agar-Degrading (agarolytic) Bacteria is physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases - enzymes which break down agarose into oligosaccharides. This physiological class branches through genii, regardless of Gram Stain status or morphology. Through a review of scientific literature we can find identification methods, optimum conditions and the
