Student name: Christopher Bowdoin Date: Thursday‚ November 01‚ 2012 Soldiers of the Tomb of the Unknown General Purpose: To inform Specific Purpose: To inform my audience about the soldiers who guard the Tomb of the Unknown Central Idea: Since 1937‚ the Tomb of the Unknown has been guarded 24/7 by an elite group of soldiers. INTRODUCTION I. Attention Material A. What where you doing at 0500 this morning? B. Lets imagine it is 0500 in Washington

Definition for antibiotic resistant bacteria: WebMD definitions: Antibiotic resistance is a type of drug resistance where a microorganism is able to survive exposure to an antibiotic. Genes can be... en.wikipedia.org/wiki/Antibiotic-resistant_bacteria Antibiotics were designed to kill bacterium that infect us. Unfortunately‚ they are indiscriminate and also kill the good bacterium that are mostly found in the large intestinal tract. This leaves a person open to reinfection‚ or other more

Aims The purpose of the two experiments was to determine the fundamental effects that temperature has on the growth and survival of bacteria. During the first experiment five different bacterial broth cultures of Escherichia coli‚ Pseudomonas fluorescens‚ Enterococcus faecalis‚ Bacillus subtilis and Bacillus stearothermophilus were individually incubated at temperatures of 5‚ 25‚ 37‚ 45 and 55°C for one week in an aim to distinguish the effect temperature has on growth and survival of the five different

In the unknown identification labs‚ we have identified our unknown as Pseudomonas aeruginosa. Pseudomonas aeruginosa is Gram negative and rod shaped that we found to be motile in the lab. Our strain of P. aeruginosa formed colonies that were round in shape and had scalloped margins on nutrient agar. On our agar slant‚ the P. aeruginosa colonies had a filiform appearance on the edges. I think we correctly identified our unknown as P. aeruginosa because we performed several different tests‚ eleven

spectrometry. We will do this by making 2‚ 4 a DNPH derivative and checking the melting points. Theory: By Using specific methods of compounds detection‚ we can match an unknown compound with a known compound because similar compounds will display similar characteristics. In this experiment‚ identifications of the unknown ketone was accomplished using thin layer chromatography‚ melting point‚ and NMR spectrometry. Thin layer chromatography is very quick but sensitive way of determining the components

The Role of Agarase in Agar-Degrading Bacteria Abstract Agar-Degrading (agarolytic) Bacteria is physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases - enzymes which break down agarose into oligosaccharides. This physiological class branches through genii‚ regardless of Gram Stain status or morphology. Through a review of scientific literature we can find identification methods‚ optimum conditions and the

I believe that the Unknown Soldier deserves just as much appreciation. The Wreath Ceremony would be an amazing honor to participate in and honor the Unknown Soldier and all this Soldier has given to protect us. This is truly an honor for whoever is chosen‚ I personally want to participate in the Wreath Ceremony because

The unknown carboxylic acid’s melting point was 108°C according to the Mel-Temp machine. The melting point is the temperature at which a solid precipitate changes into its liquid form upon heating. The melting point of benzoic acid‚ the aromatic carboxylic acid was 122°C. Thus‚ the product contained impurities which caused the solid to melt at a lower temperature than the actual temperature. Pure solids typically melt at higher temperatures while impure solids melt at lower temperatures. This is

The first test conducted on unknown bacteria 32 was the Gram stain. From this stain‚ unknown 32 was found to be a Gram-positive cocci. This test eliminated all possible Gram-negative bacteria‚ Gram-positive rods and Gram-positive spirillium. Next‚ the endospore test determined whether or not the Gram-positive bacteria contained endospores. With the use of malachite green‚ steam‚ and safranin it was found that unknown bacteria 32 did not contain endospores. This eliminated Gram-positive cocci Sporosarcina
