Microbiology Unknown 5/7/2013 Microbiology Unknown #94 The purpose of this report was to identify an unknown bacterium by applying methods that were previously learned and conducted in microbiology lab class. It is possible to identify a mixed culture by running experiments on the unknown bacteria and taking what we already know and applying it to the results. It helps to slowly eliminate any bacteria that do not correspond with the results of certain tests. An unknown test tube labeled 94 was

1. Obtain 1 gram of an impure‚ unknown substance solid. Make sure to stir the mixture before measuring the sample; record the mixture’s code in the data section. 2. Add approx. 25-50 mL of water and several boiling chips to a 125 mL Erlenmeyer flask and heat the water to a gentle boil using a hotplate. 3. On a second hotplate‚ place a 125 mL Erlenmeyer flask containing the one gram of unknown solid along with a boiling chip. 4. Using a ring clamp‚ slowly pour approx. 5-10 mL of boiling water into

Describe the major differences between gram positive and gram negative bacteria cell walls. The gram negative bacteria cell wall is a thin peptidoglycan layer and an outer cell membrane with a lipopolysaccharide layer. The gram positive bacteria cell wall is a single thick peptidoglycan layer. This wall forms in a mesh like formation of three layers of alternating material. 2. From the procedure that you have carried out‚do you feel that the Gram positive stain is a simple procedure? No‚ because

of biological system is usually preferred as the pH system‚ which determines the pH level of dilute aqueous solutions. In this laboratory‚ the data collected from the experiment will be used to graph the titration curves which help to identify an unknown amino acid. IntroductionAmino acids are simple monomers which are strung together to form proteins. Amino acids play a key cellular role in structure and function. Proteins themselves participate in nearly every physiological event in the cell. Since

Unknown Lab Report Microbiology Unknown A Sonia Kabra November 26‚ 2014 Introduction There are numerous reasons for identifying unknown bacteria. Some of these organisms have distinct qualities that set them apart from one another‚ such as the exposure to certain environments. Through out the semester in the laboratory‚ we are able to encounter some of the few microorganisms that we as humans have come into contact with. With the knowledge gained from the sessions in the laboratory‚ we can now

140 Matthew Tuthill Unknown Lab Report Introduction There are many reasons for knowing the identity of microorganisms. The reasons range from knowing the causative agent of a disease in a patient‚ so as to know how it can be treated‚ to knowing the correct microorganism to be used for making certain foods or antibiotics. This study was done by applying all of the methods that I have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium. The purpose

Themes of W.H. Auden’s "The Unknown Citizen" Conformity and Anonymity in the Modern World "Social Security Number? Birth date? Nine digit telephone number starting with area code? Mother’s Maiden Name?" In many ways‚ we are simply faceless numbers to modern society‚ not individuals with feelings and emotions and dreams. W.H.

The occasion is indicated in the lines contained in parenthesis that precede the body of the poem. As these lines indicate‚ the poem is a written monument that functions like a cenotaph: it commemorates a fallen man whose identity is unknown. However‚ unlike the soldier who falls in a battle of war‚ the battle this individual appears to be unwittingly a part of is a social battle

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
