Determining the Unknown Microorganism from a Mixed Culture Mylah Ferland‚ Rivier University MICRO 206‚ March 16th‚ 2016 Introduction: An unknown bacterium experiment‚ this experiment was done to discover what bacterium was in a mixed culture sample. This experiment worked with enteric bacteria which are members of the Enterobacteriaceae and live in the intestinal tract (Willey et al.‚ 2014). Also found in Willey et al (2014) is some characteristics of enterics such as they all degrade sugars by

Background: In Jane Horack’s article “Staphylococcus epidermidis”‚ S. epidermidis is described as “gram-positive cocci bacteria that are part of the normal flora on the skin and nasal passages.” The article goes on to say that the species was originally named Staphylococcus Albus by microbiologist Rosenback in 1884. When viewed under a microscope S. epidermidis will appear in chains‚ pairs‚ or grape-like clusters (Horak 1). Taxonomically‚ the species S. epidermidis falls in the genus Staphylococcus

in the War In the poem‚ “The Unknown Citizen‚” a short eulogy is presented at a funeral for an unidentified soldier. When providing details about the citizens life‚ the speaker instead uses impersonal facts and government based statistics‚ rather than intimate components about who the soldier was personally. The author also displays the tone of the poem as lighthearted‚ making the speaker seem untroubled about the death of the soldier. In W.H Auden’s poem‚ “The Unknown Citizen‚” the author uses his

Experiment 19 Molar Mass Determination y Depression of the Freezing Point Introduction: The most commonly used liquid is water. In this experiment we study the equilibria that can exist between pure water and an aqueous solution‚ and ice‚ the solid form of water. The heat will transfer from a higher temperature to a lower temperature. In order for water to change states of matter‚ it takes a certain amount of kinetic energy or heat. The shift from ice to water (solid to a liquid) is called the heat

Goals The main goal of this project is to learn how to identify the properties of an unknown ionic compound. In order to do this successfully the group has to use a variety of methods and run several tests on the unknown compound. By doing this the group will be able to identify the different chemical and physical properties of the compound that will help obtain the identity of the specific compound given. The group will devise two syntheses of the compound‚ and compare them for cost effectiveness

Purpose: To identify an unknown bacterial specimen using basic laboratory technique and biochemical tests. The unknown bacteria will be one of the following: Enterococcus faecalis‚ Staphylococcus saprophyticus‚ Escherichia coli‚ Enterobacter aerogenes‚ Proteus vulgaris‚ Salmonella [I assume typhimurium]‚ or Shigella [either flexneri or sonnei‚ we used both in our lab during the semester]. Procedure {and observations}: Observe bacterial colony morphology. {Colonies are large‚ beige or

Name: Name of lab partner: Date: Title: Determination of the valency of magnesium Objective: To study the quantitative relationship between the amount of reactant and products of a reaction. A known starting mass of magnesium and the measured collection of hydrogen gas will be used to determine the reaction stoichiometry and the valency of magnesium. Introduction: In Chemistry‚ stoichiometry is the study of the quantitative relationship between amounts of reactants and products of a reaction
