  • The Role And Functions Of Bacteria In The Community

    801 Words  | 4 Pages

    Bacteria are found everywhere around us and many of which are beneficial to the environment and humans, assisting in protecting the biodiversity of ecosystems within an urbanized environment. This paper aims to determine the role and functions of bacteria found within the ponds of Centennial Park in relation with other bacteria and eukaryotes. This was achieved through the process of traditional and modern microbiological techniques of gram staining, biochemical tests and 16s rRNA analysis of bacterial

  • Bacteri Bacteria And The Test Tubes

    1994 Words  | 8 Pages

    Bacteria Growth in Different Test Tubes Introduction The purpose of this lab is to learn about restriction enzymes, plasmids, and cloning genes. In class, we learned a lot about the structure of DNA and genes, which were both very helpful while performing this experiment. Restriction enzymes have the ability to cut DNA at specific sequences. Plasmids are perfect for genetic engineering because they can replicate and initiate transcription. Performing this experiment helped us learn more about the

  • Transformation Of Escherichia Bacteria And Dna

    1348 Words  | 6 Pages

    Transformation of Escherichia coli in different concentrations of Plasmid DNA Introduction This report discusses an experiment which students have to transform and plate competent Escherichia coli in different concentrations of plasmid DNA. This experiment uses four concentrations of plasmid DNA to perform four transformations. These concentrations are namely, 5 µl of distilled water, which acts as the control in this experiment; 2.5 µl of undiluted plasmid DNA; 1.0µl of undiluted plasmid DNA; and

  • Essay Antibiotic Resistance in Bacteria

    757 Words  | 4 Pages

    Antibiotic Resistance in Bacteria For about 50 years, antibiotics have been the answer to many bacterial infections. Antibiotics are chemical substances that are secreted by living things. Doctors prescribed these medicines to cure many diseases. During World War II, it treated one of the biggest killers during wartime - infected wounds. It was the beginning of the antibiotic era. But just when antibiotics were being mass produced, bacteria started to evolve and became resistant to these medicines

  • The Dangers Of Drug Resistant Bacteria

    1243 Words  | 5 Pages

    “Drug Resistant Bacteria According to Cable News Network, reported that, “the Center for Disease Control is categorizing antibiotic-resistant organisms by threat level. That’s because, they have estimated, more than 2 million people get antibiotic- resistant infections each year, and at least 23,000 died because current drugs no longer stop their infections” (Falco,1). Antibiotic-resistance is becoming a growing issue in society today. “A 59-year-old man was hospitalized with Klebsiella pneumonia

  • Antibiotics Combat Infectious Bacteria

    1365 Words  | 6 Pages

    ability to kill or hinder the growth of bacteria. Antibiotics contain compounds that are naturally produced by organisms to combat diseases caused by microbes. Discovery of penicillin by Sir Alexander Fleming became the first stepping stone of many new antibiotics of today’s modern medicine. Antibiotics typically invade the very components that make up bacteria, such as cell walls and metabolic pathways (Sato et al., 2014). However, frequent mutations of bacteria cause today’s strains to become more

  • Garlic Effects Bacteria Essay

    1220 Words  | 5 Pages

    of garlic when exposed to two different strains of bacteria. Garlic has been used throughout many centuries to treat common ailments from seasickness to intestinal parasites (Ankri and Mirelman, 1999). With the information gathered from this lab, we can conclude whether or not our predecessors were on the right track with this natural remedy. Another reason for doing this experiment is to observe how natural antibiotics affect modern bacteria. With our modern medicine, people are diagnosed with

  • The Unknown Bacteria Plate Chosen

    926 Words  | 4 Pages

    Unknown Bacteria I. Introduction The unknown bacteria plate chosen was plate #2. It was identified to be Micrococcus luteus. It is a gram positive, Coccus bacteria that is commonly found in dust, water, soil, and the air. M. luteus also thrives in the human mouth and upper respiratory tract. Sir Alexander Fleming discovered it in 1928 before he identified penicillin. It is part of the normal flora on human skin as well as other mammals. Since it is part of normal flora it is normally not pathogenic

  • Bacteria Transformation in Biotechnology Essay

    1673 Words  | 7 Pages

    Abstract Some bacteria are able to go through transformation making new combinations of genes. Transformation is a way of gene variability in bacteria. This experiment is based on the transformation mechanism of bacteria and gene regulation. The bacteria used for the experiment was Escherichia coli and the genes introduces for the transformation were: gfp and bla by a pGLO™ plasmid. After the insertion of the target genes and growing the bacteria on specialized LB media, it could be seen that the

  • The And Chemical Kill Off Bacteria

    720 Words  | 3 Pages

    experimenting how well different products, natural and chemical kill off bacteria. I’ll be testing different products such as Vinegar, Manuka honey, Ajax, tea tree oil and Dettol Hand Sanitizer. By testing the rate at which these products kill off bacteria I will be able to determine the most effective products and compare the differences between each products efficiency. Vinegar: Vinegar has been efficiently tested in killing bacteria. An experiment done in February 201 found that Vinegar has a large
