The purpose of the unknown bacteria lab assignment was to select an unknown bacteria culture and‚ through a series of metabolic tests‚ identify which bacteria genus resided in the pure culture received. A nutrient broth inoculated with bacterial culture (numbered 45‚ henceforth referenced as U45) was selected and a streak plate was made to isolate a pure culture for use throughout the assignment. From the streak plate‚ several slides were made to determine the morphology of unknown 45. A Gram stain

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

Identification and Diagnosis of Unknown Enteric Bacteria in an Infected Patient Using an Enteropluritube Brooke Addario 2/16/2015 BIO 488C - Section J TA – Jacob Karsten Introduction: Enteric bacteria are members of the Enterobacteriaceae family of microorganisms. These gram negative‚ rod shaped‚ facultative anaerobes are found in the intestinal tracts of humans and animals. Enteric bacteria can be pathogenic; however‚ they are also a normal part of human bacterial flora and are therefore

Dr. 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

Phelps‚ Biology 205 MW 2:10pm. Unknown Organism Paper The unknown organism tested in the Mesa lab was collected from in between the toes of my puppy‚ Riley. The original culture grown consisted of dozens of visibly different organisms of varying colony colors and growth patterns. I chose to test a smaller‚ red colony for my experiments. Based on its gram reaction and oxygen requirements‚ the following tests were performed to reach my presumptive ID: Test Performed Result Gram Stain +

In an isotonic environment‚ the amount of water and solute are the same both inside and outside of the cell. As water drifts into the a cell‚ the same amount flows out creating a balanced environment both inside and outside of the cell. When there is a high level of
