    Sam Afflu Section H1 Microbiology 680 390 Lab Report 2: The Isolation and Identification of an Unknown Bacteria Abstract This laboratory experiment’s objective was to take a pure culture and isolate it from a mixed culture. The other part of the objective was to ascertain what species of bacteria that the pure culture was. The hypothesis made stated that so long as lab protocol was followed, the unidentified culture would be positively recognized/identified. An isolated pure colony of the

  • Antibiotic Resistant Bacteria And Antibiotics

    1695 Words  | 7 Pages

    resistant to antibiotics due to people that are sick and receive an antibiotic from their doctor; but as soon as they start to feel better they stop taking the antibiotic. If you stop taking antibiotics before the treatment is over can cause the bacteria to return stronger and this time resistant to that antibiotic. Another reason that certain bacteria’s are becoming resistant to antibiotics is due to patients expecting doctors to prescribe antibiotics to them even though they have a viral infection

  • How Do Bacteria Divide?

    1600 Words  | 7 Pages

    How do bacteria divide? Introduction Cytokinesis is the process of producing to progeny cells (Scitable by nature education, 2014); the main process by which bacteria reproduce is asexual producing genetically identical offspring. The most common process of cell division in bacteria is binary fission. In this essay I intend to explain some aspects of DNA replication and septation – including the synthesis of peptidoglycan in the new cell wall – using the model organism Escherichia coli. Also, I will

  • Factors Affect The Growth Of A Bacteria

    1374 Words  | 6 Pages

    There are numerous influences that can affect the growth of a bacteria. These influences include the presence of oxygen, pH, the accessibility of water, and temperature. The abundance or lack thereof for each of these factors can determine whether a bacterial cell is able to propagate or if it will ultimately die. Additionally, the intensity of these factors can also determine the amount of growth seen. In order to observe this relationship one of the influential factors was chosen and the rate

  • Essay On Gram-Negative Bacteria

    1045 Words  | 5 Pages

    and the delivery of different components via these vesicular structures are common among Gram-negative bacteria, especially during the infection. But there are few studies on EV formation in Gram-positive bacteria. It has become evident that MVs serve as transport vehicles containing different cargoes. Although there are some differences in cell structure of Gram-positive and Gram-negative bacteria, many

  • Bacteria and Degrees Celsius Essay

    765 Words  | 4 Pages

    Bacterial refers to killing bacteria and bacteriostatic refers to inhibiting the growth of bacterial cells. Sterilization is the complete destruction or elimination of all viable organisms. There is no degree of sterilization either it is or is not. Disinfecting is lowering the number

  • The Presence of Bacteria in Unexpected Spots

    701 Words  | 3 Pages

    Locations where Bacteria can be Found: Similar to other germs like cold viruses, bacteria can live in various unexpected locations or spots. This is primarily because bacteria are actually found anywhere since they are in water, plants and animals, air, and the soil. The presence of bacteria in unexpected spots and locations originate from their ability to thrive in the most uninviting and forbidding places on the planet. Actually, some medical professionals state that germs like bacteria that attack

  • Bacteria and Fungi Research Paper

    870 Words  | 4 Pages

    What are bacteria? Bacteria are very different from viruses. First of all, bacteria are much larger in size. The largest virus is only as big as the very smallest bacterium (singular for bacteria). But bacteria are still microscopic and cannot be seen with the naked eye. They are so small that the sizes of bacteria are measured in micrometers (10,000 micrometers = 1 centimeter). By comparison, the head of a pin is about 1000 micrometers wide. Though more complex than a virus, the structure of a

    Bacterial Growth Lab Priyanka Savaliya Mrs. Bronson September 18th/2013  Bacterial Growth Lab Introduction: In this bacteria growth lab, students from Mrs. Bronson’s biology class collected bacteria samples from around the school and grew them in petri dishes filled with agar which were prepared one day before in advance with the expectation that after one week, distinct bacterial colonies will grow larger in numbers so that the human can see them. These single-celled prokaryotes were grown on agar

  • Bacteria Are The Smallest Living Organisms

    2610 Words  | 11 Pages

    Lab Report: Unknown #1 Paola Rosales 302672960 Professor Youssef INTRODUCTION: Bacteria are the smallest living organisms, they are prokaryotic and have a simple cell structure. They do not contain a nucleus, and are unicellular. Bacteria are the most abundant microorganism. They are among the earliest forms of life that appeared on earth billions of years ago. They can grow in different temperatures and many exist naturally in our human flora, such as staphylococci. Growth within different
