Tanti Lim Thurs AM Unknown Project I. Introduction The purpose to this lab was to isolate and identify two unknown bacteria from a mixed culture provided to us. This study was done by applying all of the methods that have been instructed on thus far in microbiology laboratory class. Each test performed‚ provided us with some key information about the unknown microbes in question . The identification of unknown bacteria is a time honored part of microbiology courses. It will challenge

an Unknown Compound Purpose: The purpose of this experiment was to separate a mixture of two or more unknown compounds and identify them based on their melting point and reactivity with an acid or a base. Compound studied/Reactions: The organic solvent used in this experiment was methyl t-butyl ether (MTBE‚ 2-methoxy-2-methylpropane). The unknown that dissolved in the MTBE‚ but was insoluble in water. MBTE is very volatile and flammable. It was determined in the experiment that the unknown was

Introduction The ability to identify metals is an extremely important one. With this ability‚ we can correctly assign different traits‚ and use the metal in its most suitable environment. This is important to many industries‚ where metals play an increasingly large role. Determining the identity of the metal is paramount to determining what conditions to use the metal under. This seemly simple task is‚ however‚ can be quite complex‚ as there are many ways by which one can identify a metal‚ each with varying

My Identity Physically‚ I am an Asian boy with somewhat a smooth hairstyle. I’m relatively chubby with about 168-centimeter height and 80-kilogram weight. Working out every single day and trying to build a ripped body aren’t my things. However‚ I do love sports‚ a whole lot. Basketball‚ table tennis and swimming are hobbies that I enjoy doing real much whenever I have some free time or I simply need a stress reliever. The way I look and the way I speak may make people think that I’m an Asian

Requirements for Unknown Report You have been provided a mixed culture (a gram positive and a gram negative) from which you should have isolated each type of organism‚ described their colonies on a TSA plate‚ and described their cellular morphology. You were graded on this activity separately. After you have isolated your gram negative in pure culture you will be subjecting it to various biochemical tests and making observations about the cells‚ colonies‚ growth temperature preferences‚ etc. in

Purpose: The purpose of this experiment was to identify one ketone with Thin Layer Chromatography and one using NMR 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

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
