– Identifying Bacteria Bacteria identification is accomplished in a number of ways. Two common tools microbiologists use to identify unknown bacteria include dichotomous key and biochemical tests. The dichotomous key is useful when a microbiologist only needs to know which group an unknown microbe belongs to on a general level. When a microbiologist needs to identify a specific bacterium‚ biochemical tests are used. PART ONE: GENERAL BACTERIA IDENTIFICATION Review the dichotomous key in Figure

MIC 230 Unknown Identification Report The objective of this experiment was to identify an organism from a mixture of two unknown bacterial species. In order to accomplish this‚ I first plated my unknown mixture on Tryptic Soy Agar (TSA)‚ Columbia Naladixic Acid (CNA)‚ and MacConkey’s Agar (MAC) plates. After 48 hours of incubation‚ it was unclear that two different bacterial colonies had grown on my TSA plate. Only one type of colony was evident. However‚ it was apparent that I had successfully

Abstract: A qualitative analysis experiment was conducted to determine the identity of an unknown aldehyde or ketone. The tests include a Tollens test‚ a Schiff test‚ an iodoform test‚ and a derivative melting point test. The data of the first three tests was inconclusive. The final derivative melting point test was utilized to successfully determine that the unknown was the ketone‚ Propiophenone. Introduction: Qualitative analysis is a method or series of methods used to determine the

CHAPTER 5 DISCUSSION 5.1 Analysis of Trace Metal by FAAS Based on the table (4.3 and 4.4) the trace elements was detected by using the flame atomic absorption spectrophotometry analysis. The trace metal can be detected by the FAAS within 15 seconds to 30 seconds of each soil sample. Before the samples were analysis with the FAAS‚ the blank samples were run in the machine for each element that was being analyzed. Their absorbances were read. The mean of each blank was calculated and

Identification of a Hydrate Based on Percent Water Varun Wadhwa 11/19/12 Introduction The identity of an unknown hydrate was determined by massing the hydrate before and after heating and calculating the percentage of water. Procedure First‚ we cleaned‚ dried and heated an evaporating dish for five minutes on an iron ring with the Bunsen burner and massed it. Then‚ we added 2 grams of an unknown hydrate and calculated the mass of that. Next‚ we used gradually increasing heat for

Separation and Identification of Plant Pigments by Paper Chromatography Biology 1107L Introduction All living organisms require energy for their chemical processes. The ultimate source of this energy is the sun. Plants convert light energy into the chemical energy of sugars. During photosynthesis pigments are used to capture light energy. Pigments of green plants can easily be separated and identified using a technique called paper chromatography. The purpose of this

Systematic Identification of Bacillus subtilis and Serratia marcescens Through a Battery of Tests and Plates Introduction: The purpose of this experiment was to use a systematic battery of tube tests and plates designed to lead to identification of two unknown bacterial species‚ from the combination of all results. A sample of bacteria was used‚ labeled “Sample 4”‚ from which both species was to be obtained‚ one gram positive and one gram negative. Table 1 is a list of the possible bacteria to

EnCase is a standard of the industry and found in most‚ if not all‚ computer forensics shops. So having the EnCE certification demonstrates to employers that you have mastered the tools that they use in their forensic labs. In addition‚ passing the EnCE practical was a major confidence booster for me and I have used many of the techniques that I learned as a result of the EnCE practical during my "real" analysis. In summary‚ in order to determine the proper computer
