  • The Role of Agarase in Agar-Degrading Bacteria
    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...

Emily Koch noticed that her mom, who eats garlic, has fewer colds than other family members, so she decided to see if the stories about garlic are true. You can get a look at her project display in the figure. Figure: Project display for “Garlic and bacteria inhibition.”...

  • Bacteria Growth and Glucose Percentages
    Bacteria’s Growth Affected by Various Glucose Percentages This lab tested whether or not different glucose levels activated bacteria growth. My lab group and I wanted to figure out, if more glucose was spread on the bacteria plates, would there be more bacteria growth in the agar plate. My group predicted that with 25% glucose (the highest percentage of glucose), the bacteria growth would be the greatest. In order to conduct this experiment, my group had 3 ager plates. One plate had 0%...

    Introduction In my report I will discuss what I did as an experiment and what I hope for it to achieve. Firstly I carried out an experiment to assay the effectiveness that a range of disinfectants have on the growth of ecoli and whether or not it can prevent it from growing. From the experiment i should be able to see that some disinfectants have a greater effect than others do. From this I shall then draw a conclusion and evaluation on what was the most effective, and could there have...

  • Lab experiment 7 questions and conclusion
    Experiment 7 Questions 1. Coccus shape bacteria are more structurally sound. 2. Alpha will turn green on the plate because the bacterium is outcompeting the body for oxygen because there is an iron binding site. Beta hemolysis is cellular death which means that when it is present in the body it is releasing an acidic byproduct or a basic byproduct which will crush the structure of the blood cells. Alpha outcompetes with the blood for oxygen while beta hemolysis kills the competition for...
