Bacteria Essay

Introduction: Bacteria and Fungi are important contributors of the living life. They however differ in their colony/ color/ size/shape/appearance. Bacteria are generally small in size but large in colonial structure, they are usually in the form of coccus, bacillus and spirillum, many times bacteria are of vivid colors because they have chlorophyll which also absorbs the light of different wavelengths which create natural colors of brown, pink, blue, orange and purple. Fungi on the other…

Many things live in your mouth. Bacteria live in it. You ask, “What kinds of bacteria? Why can’t we sense it? Is it good or bad?” Be brave, take a reading adventure and find out answers to all these questions, and more. How much bacteria exactly? A lot of bacteria live in your mouth, colonies, and colonies. About 6 billion live in your mouth. That’s interesting because about 7.3 billion people live on earth. All those bacteria that live in your mouth actually live in diverse communities,…

Introduction Bacteria is a small prokaryotic that is a single celled organism. There are many kinds of bacteria that are used daily in the medical or research field. Escherichia coli is a bacteria that is found in the intestines that is not harmful and is used by many laboratories where they perform many experiments with it. Researchers value Escherichia coli for its genetic simplicity (it has about 4400 genes, versus the 30,000 in a human cell) and for its fast growth (Feltman). One of the…

While he was growing bacteria in a petri dish, he notices the appearance of a type of fungus. The contamination caught the attention of Fleming. He realizes that he had found a substance that had the power to kill bacteria. Fleming continued to grow more fungal mold and tested it on different kind of bacteria. Additionally, he tested it on healthy mice in which he obtained an adverse effect from it. Fleming figured out that there were numerous substances that can kill bacteria. However, he…

Involving the use of living organisms like bacteria in industrial processes due to their natural metabolic capabilities are known as biotechnology. They are used a several ways such as manufacturing of foods, cosmetic products and production of antibiotics, probiotics, drugs, vaccines, insecticides, and enzymes. In addition, they are also being widely used in the genetic engineering. Nowadays, bacteria are commonly used in the food industry for the manufacture of dairy products such as cheese,…

Effectiveness of Bacteria Killing Agents Bacteria are everywhere, you may not be able to see it, but it is present. Many different bacteria killing agents exist. For example, there are antibiotics, which can be helpful, but harmful, and are usually prescribed by doctors. Some people also use essential oils whish are safer and healthier. Bacteria can be good and bad. Good bacteria help to keep you healthy. The bad bacteria can make you sick. Poor diets and constipation can lead to bad bacteria.…

1. Penicillin kill bacteria by meddling with the capacity to blend cell divider. In this grouping, Escherichia coli were brooded in penicillin for 30 minutes. The bactericidal kills the bacteria. Also, bacteriostatic is a keeps bacteria organisms from developing. 2. Antibiotic resistance happens when bacteria organisms change somehow that decreases or wipes out the adequacy of medications, chemicals, or different specialists intended to cure or avoid contaminations. The microscopic organisms…

infections in two people. In order to treat the infections, we had to conduct a Grams’ test to figure out what kind of infection the children had and then identify the antibiotic that would best treat the infection or if they were antibiotic-resistant bacteria. For this experiment, my hypothesis is that both culture’s A and B will not be antibiotic-resistant and will have at least one antibiotic that will be able to treat the infections. The null hypothesis is that culture’s A and B will be…

presence of disease-causing bacteria in drinking water. One the simplest way to tell if there is a disease-causing pathogen in the water is the presence of coliform. Just like most of the microorganisms, coliform bacteria, a Gram-negative bacteria that belongs to the bacterial group Enterobacteriaceae, can be found mostly in soil, surface and water. In addition, coliform can be found in the digestive tract, especially in the intestines of animals and humans. While coliform bacteria…

After part 1, the experimenters found two things about the Bacteria: First, that the bacterium was bacilli (rod) shaped. This was determined by viewing individual cells through a microscope at 400x power. Secondly, that the bacterium was most likely a Gram-stain-negative because it appeared to be a pink color after gram-staining. This had several implications: The experimenters now knew the bacteria’s cell wall composition, its outer membrane composition, peptidoglycan concentration, outer…
