Pros And Cons Of Bacteria
1690 Words7 Pages
Introduction
Bacteria are everywhere some harmful and others not, without bacteria the world would be nothing. In this research paper I will be discussing bacteria, anti-bacterial agents, pros and cons of bacteria and my conductive experiment on the growth and the killing of bacteria.
Bacteria are single cellular organisms that most commonly reproduce through means of binary fission. They were first discovered by Anton Leeuwenhoek in 1676 and are classified as Monera in the five kingdom classification system. Anti-bacterial agents kill or inhibit bacterial growth.
My conductive research consisted of making agar, growing bacteria that I received from the inside of a human’s mouth and using different toothpastes to see which brands work better.

Gram positive organisms are susceptible to antibiotics such as penicillin (Introduction to Penicillins, 2012). This is because, gram positive bacteria have a thick layer of peptidoglycan, a sugar and peptide coating that gives a cell its shape and helps it stay intact (Wiley, 2004). The original antibiotic, penicillin, and the likes are used to treat infections caused by bacteria that are gram positive. Based on the scope of the experiment and the materials needed, a budget estimate of $1,000.00 would be needed to buy reagents and materials for this experiment.

Adding copper pennies to the vase helps preserve the flower and help it live longer. A copper penny could be used as an antibacterial agent. It helps the flower stay alive longer because the copper prevents the fungi from growing in the inside, which could kill the flower. The help of the penny copper means that there will be none or limited fungi which is one factor why the flower could die faster.

Bacteria are living things that have only one cell. Under a microscope, they look like balls, rods, or spirals. Many are helpful. Some bacteria help to digest food, destroy disease-causing cells, and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt.

These microorganisms are used to teach us how multicellular organisms came to be and how they can survive today. These small, microscopic organisms are so unique that the identification of them is paramount in the advancements of science. Knowing the chemical makeup, the shape, and the biochemical processes is important in identifying these organisms to understand how they survive and where. A number of tests can be ran on an unknown bacteria to determine their ideal

The Unknown Identification Lab was an experiment that provided the opportunity to apply all the tests that were learned in the semester of lab, to identify the two bacterias that remain unknown. Gram- staining and two other tests will be used to identify the unknowns. This experiment is crucial to the understanding of each test, and can benefit in the ability to identify the characteristics of specific bacteria. Having a clearer understanding of the bacteria can further the research of bacteria for medicine, such as antibiotics. The understanding can also help the development of research in the environment.

Introduction: Microbiology is the study of the microbial world, which is composed of microorganisms that are too tiny to be seen with a naked eye. This project demonstrates the significance of correctly identifying unknown organisms with methods and techniques acquired in the laboratory as they can make or break one's ability to accurately isolate and identify various species. Studying microbes enables oneself to have an insight on not just their structure or how they function, but how they have an impact on organisms and their environment around them as they can be found nearly anywhere. The importance of the process of identifying unknown bacteria vary from determining the causative agent of a disease, to testing if a specific food or fluid is safe to consume, and simply knowing what is present

Bethany Brookshire, the author of the article “New gene resists our last-ditch drug” found in the Society for Science & the Public, invoked fear and urgency in teen readers fascinated with biology and health. Throughout her article, Brookshire establishes that doctors, farmers, and everyday citizens should be cautious in the use of antibiotics and use methods to limit the spread of harmful bacteria worldwide. She gains her readers’ attention and trust by quoting information from several scientists in different fields and from different parts of the world. Although her syntax was rigid and overly simplified, Brookshire connect to the teen readers ****** Brookshire is professional and *** in her popular article. She maintains an unbiased standpoint

In the laboratory, identification of an unknown bacterium is often necessary. In the lab, a random sample consisting of three different bacteria was selected. The sample contained one gram-positive, one gram-negative paracolon, and one gram-negative coliform. The purpose of the experiment is to identify each of the three species that the mixture contained. After receiving an unknown mixture, the sample was streaked for isolation onto TSA, blood agar, and MacConkey plates.

Bonnie Bassler, a molecular biologist talks about her discoveries about the possibilities of communication between bacteria, and demonstrates the depths of bacterial quorum sensing, the method in which bacteria “talk” to each other. Bassler states “you think of yourselves as human beings, but I think of you as 99 percent bacterial” (Bassler, 2009). She then talks about how human bodies are made up of cells but in reality, the body is made up of fewer cells and mostly bacteria. Bassler thinks of humans at 90-99% bacteria for two reasons. First, humans have about 1 trillion human cells in them at all time, while at the same time we have 10 trillion bacterial cells in us as well, meaning we are 10 times more bacterial than human relative to the cells we exhibit.

Antibiotics the Good and the Bad Is society aware that they could be facing a major problem created by themselves if antibiotics are not used correctly? Resistance against antibiotics has just recently become a problem. Farmers use antibiotics by giving them to their livestock, which does have many benefits, but also has a downside after being harvested. Overusing antibiotics is thought to lead to resistant strains of bacteria that no antibiotic can cure. Some believe that antibiotics should be used in food animals because it treats illnesses and promotes growth, while others believe antibiotics should not be used because the resistant strains could end up affecting humans through their meat.

Biological warfare has been used “…since the onset of human civilization…” (Kostadinov and Galabova, 2010, p. 295). If populations were able to use biological agents back then, it is naïve to think that terrorists will not use them as a weapon of mass destruction. The 2001 Anthrax attacks were the first Anthrax attacks to occur in the U.S. in 25 years (NPR.Org, 2011, p. 2). This attack proves that biological warfare will always be a risk.

Bacteria that causes disease are called pathogens. The disease is caused by a poison called exotoxin and endotoxin produced by the bacteria. Another microbial life are protist. They are unicellular eukaryotes. Types of protist includes protozoans and slime molds.
