MANIPULATION OF BACTERIA INTRODUCTION: In this experiment that we performed‚ there were many methods that were used to help us manipulate and identify the bacteria E.coli on a MacConkey agar plate. The first part of the experiment involved the methods of manipulating‚ identifying and counting the bacteria and the second part was to find out whether the bacteria E.coli was the only type found in the given area by gram staining. E.coli was the chosen bacteria for this type of experiment. It is

these pathogens and their related epidemiology has become increasingly more important. The purpose of this study was to identify an unknown bacterium in a controlled laboratory environment over a 5 week period. Utilizing a variety of differential testing and staining methods learned in the microbiology course‚ students were to determine the identity of an assigned unknown organism. Observations were made and recorded each week to narrow down the scope of identification. Data has been presented in

Margaret E Gibson July 20‚ 2009 Microbiology Dr. Metera Lab Report 3: Labs 7 and 8- Metabolism and Biochemical Tests Abstract This experiment focused on metabolism and biochemical tests. The goal of performing these tests was to differentiate microbes from one another and to compare how metabolic and biochemical processes differ from species to species. The tests performed include: the Fermentation of Sugars Test (sucrose‚ glucose‚ and lactose)‚ the Urease Test‚ the Fermentation

Lab Report #1: Observing Bacteria Microbiology Abstract: This lab exercise familiarized the student with the use of a microscope by observing and identifying various different slides under the microscope. The student practiced observing the given slides under the 10x‚ 40x‚ and 100x (oil immersion) objective lenses‚ which allowed for the identification of the different organism’s shapes and sizes. Purpose: The aim of this exercise is to equip the student with the knowledge

“Fighting Invisible Killers” Scholastic Scope: The Language Arts Magazine January 2014 Edition‚ pages 5-9 Bacteria surround us every day. These little “bugs” are invisible to the eye and most do not harm us. Many are necessary for us to survive‚ like the bacteria in our stomachs and intestines that help us to digest food. But some bacteria are very dangerous to us. Addie Rereich became very sick in May 2011‚ when she was 11 years old. What started as something that her doctors and mother
