Identification and Recreation of Unknown White Compound #643p November 13‚ 2012 INTRODUCTION: The identity of the unknown solid white compound is determined and verified through a series of tests which uncover physical and chemical properties necessary for identification. A new sample of the same compound is then created to further prove the accuracy of the identification. The compound must be identified in order to be used. For example‚ KCl is used in medicine‚ scientific applications‚ and

Annie Cu Gallardo BSE-Biological Sciences III-3 Microbiology (Lecture) Microbiology Written Report REPORT NO. 1 Prokaryotes: Bacteria Most of us have been conditioned to think of bacteria as invisible‚ potentially harmful little creatures. Actually‚ relatively few species of bacteria cause disease in humans‚ animals‚ plants‚ or any other organisms. In fact‚ all organisms made up of eukaryotic cells probably evolved from bacteria-like organisms‚ which were some of the earliest forms of life.

Microbiology Laboratory Report Identification of Unknown Bacteria 03/10/05- 04/01/05 Authors: Richard Hendricks‚ Jessica Prebish; NMU Abstract: Broth culture 16 was randomly selected by our group and subjected to qualitative tests for taxonomic identification. The culture did appear homogenous throughout the testing period and is currently retained by Northern Michigan University’s department of Microbiology. We suggest that culture 16 is an example of Escherichia coli. Background: Techniques

This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous in his stool. The patient had no pain but mild discomfort during bowel movements. The doctor noted inflammation of the lining of the rectum. The
