Bacteria Essay

Identification of bacteria can be a difficult process due to the fact that individual bacterial cells can possess similar structural morphology to other types of bacteria. As we have demonstrated in previous lab experiments there are key biological and chemical processes that are characteristic to different types of bacteria. Using various biochemical tests we can evaluate and detect these different processes to aid in our identification of unknown bacterial samples. The implications of these…

Exercise 2: Observing Bacteria Cultures in Yogurt Firstly, we created an incubator using a Styrofoam cooler with a removable lid and a small hole in the top which was used for placing a 7 watt light bulb in order to maintain a Microbe growing temperature of 35-37° Celsius. We also monitored the temperature with the use of a thermometer. A teaspoon of yogurt was then placed into a clean plastic container with lid. The container was then placed in the Styrofoam incubator, which was not…

ADOPT A MICROBE Part 3 Marissa DiMauro BIO 250-550 In the selected article by Sofie Rombouts et al., there is a problem posed by the bacterium Pseudomonas syringea pv. porri. The issue is due to the bacterial blights produced by this pathogen, which hurts leek cultivation. This has caught scientist’s attention, as these cases of bacterial blights have been increasing and are causing economical losses in the process. Although there are different methods for disease…

Article #1: How “Dead” Bacteria Return to Life Summary The article, How “Dead” Bacteria Return to Life, discusses how bacteria that can be switch to a dormant stage, can survive when no growth is deemed possible. The people working in these findings are international researchers working with Professor Karl Forchhammer and Alexander Klotz at University of Tübingen 's Interfaculty Institute of Microbiology and Infection Medicine. It is stated that the cells stop photosynthesis and begin to…

everywhere throughout the world. Those microscopic life forms are known as bacteria. Bacteria can survive in the coldest or hottest temperatures around the earth. Known to be unicellular, bacteria live within human bodies and also in the food we eat. Not only that, they are everywhere. Bacteria plays a major role in the human body. For an example, it is bacteria located in the intestines that help with food digestion. Even though bacteria are plentiful and prevalent throughout our daily lives,…

Pathogens may be viruses, bacteria, protists, or fungi they are just microorganisms that can cause diseases. Bacteria are microscopic and once bacteria find their way into the body they release toxins that make us feel sick. Examples of bacterial infections are cholera, typhoid, food poisoning, and gonorrhea. Although bacteria are very small viruses are much smaller, they are among the smallest organisms we know of. Viruses not only enter the body but they enter cells and reproduce inside cells,…

CTQ 04: Fundamental Concept:  An agent lethal to bacteria is bactericidal and which inhibits the growth of bacteria is bacteriostatic.  Effectiveness of control agent depends on its concentration, time of exposure and its activity (cidal or static) Solution: • Microbial control agents are of two types based on their effect on microbial cells which are either bactericidal or bacteriostatic. • Bactericidal antibiotics kill (cidal) the bacteria Ex: Polymixin B is a bactericidal agents which…

Bacteria are single-cell organisms can appear everywhere. The bacteria live in every climate and location on Earth (in the air, water or land...). When prompted to "bacteria", many people assume that it means negative, but the bacteria perform many important functions for the organism and the environment. The majority of bacteria harmful to humans but still have some kind of beneficial. In the gastrointestinal tract of humans, the good bacteria that aid digestion, producing vitamins and immune…

Lives of Bacteria” by Bonnie Bassler, she talk about bacteria and how they operate together to do things. She starts by stating bacteria is the oldest living component on earth, they have been here for billions of years. Bacteria are single celled microscopic organisms with one strand of DNA. Their life includes consuming nutrients from their environment, growing, and then dividing into two cells. Bacteria are continuously growing and dividing. Bassler continues her discussion of bacteria by…

Bacteria! They're everywhere, and they are usually harmful. But did you know that some bacteria are actually good for you?.. Good bacteria, called Probiotics, are friendly to the human body, and actually are very important to have inside of us. While many of us have heard of probiotics some people are still unsure or even confused as to exactly what they are and what they do. I have been asked number of times to provide some clarity on this subject. The following is a Q & A of the most common…
