    Bacteria are inoculated (introduced) and cultured (grown) in the laboratory for test studies to determine their morphology (the shape, size, arrangement, and internal structures) and pathology (ability to cause disease). Inoculation has to be performed without adding other microbes or contaminants. Aseptic (sterile) technique is the process of growing pure (uncontaminated) cultures, and is essential for proper characterization of a bacterium. Aseptic technique includes the use of sterile media and equipment. The sterility of these tools is maintained by proper handling procedure, which prevents the introduction of contamination. The basics of aseptic technique are:…

    Bacteria identification is accomplished in a number of ways. Two common tools microbiologists use to identify unknown bacteria include dichotomous key and biochemical tests. The dichotomous key is useful when a microbiologist only needs to know which group an unknown microbe belongs to on a general level. When a microbiologist needs to identify a specific bacterium, biochemical tests are used.…

They have certain identifiable features that distinguishes them from Eukaryotes such as: “Their DNA is not enclosed within a membrane” and “they usually divide by binary fusion, organelles are not encompassed within the membrane and the cell walls usually consist of complex polysaccharides peptidoglycan” (Tortora, 2013).…

    Unknown Bacteria Essay

    Usually the media is based on a known environmental condition range that they tolerate and most groups can not. An example is Manitol Salts Agar (MSA). This media contains salts that most organisms can’t tolerate due to their osmolity ranges. Microbes that normally exist under these conditions are able to grow. MSA is usually used for Staphylococcal species. Differential media provides chemical compounds that bacteria metabolize differently. The difference is observed by a colony or media color change. This media is often used to differentiate between groups of organisms with the same morphology and biochemical resemblances. Eosin Methylene Blue (EMB) is an example that can be used to differentiate between various Gram (-) rods of the intestinal tract. Escherichia coli and other enteric bacteria are able to ferment. Lactose fermentation results in a colony color change ranging from pink to purple.…

    Fighting Bacterial Growth

    The purpose of this lab was to determine the effectiveness of antiseptics, disinfectants, and antibiotics on bacteria. The hypothesis was that if bleach was used, it would be the most effective because bleach is commonly used to clean and disinfect various things. The variables that were tested were antibacterial soap and Scope mouthwash for the antiseptics; bleach and ammonia for the disinfectant; and Cipro, erythromycin, and tetracycline for the antibiotics. All of these chemicals were used on the bacteria M. luteus. Two Petri dishes were covered in the bacteria and split into four quadrants, in which each had a disc containing one of the chemicals stated above. One quadrant was left alone with no chemicals for the control group. The dishes were then left for the bacteria to grow, and once obtained again it was obvious that some of the bacteria was killed by the chemicals. In individual data, there was a zone of inhibition of 3mm in the antibacterial soap; 10mm in the Scope mouthwash; 2mm in the bleach; no zone of inhibition around the ammonia; 10mm in both the erythromycin and the tetracycline, and 15mm for the Cipro. The average length of the halo of inhibition in antiseptics was 8 mm in the E. coli, and 6 mm in the M. luteus. The average length of the halo of inhibition in the disinfectants was 12mm and 11mm respectively. For the antibiotics, it was 7mm and 9mm respectively. The data represented the hypothesis because for both the E. coli and the M. luteus, the largest zone of inhibition was in the disinfectant; and more specifically, the averages were 28mm in the E. coli and 18mm in the M. luteus in the bleach. In some Petri dishes, the bleach also killed bacteria in the other quadrants, indicating that it killed a lot of bacteria. This also affected some measurements for the other chemicals, because the zone of inhibition for the other chemicals around the bleach could have been caused by the bleach instead of the other chemical.…
