Microbiology Lab ReportPractica #1BTC307LAmber AmelingmeierThursday‚ September 18‚ 2008OBJECTIVESIn this lab experiment two different types of bacteria‚ Escherichia coli and Staphylococcus aureus‚ were grown singly and mixed on four different types of agar in order to observe the varying morphologies within the colonies. Resulting data was analyzed to provide understanding of the use of differing culture media and conditions for bacterial growth. RESULTSFour different agar types were used in this

Organ Harvesting Research Paper We have all heard about the stories and have seen the movies in which the protagonist wakes up in a tub covered in tons of ice and stitches in his side only to realize that he was a victim of organ theft. There have been many movies surrounding this horrid topic‚ and many people believe this concept is fictitious; however these movies have partial truth to them. There are many cases across the globe in which people have been given faulty organs‚ and cases in which

Microbiology Archae are tiny microbes with no cell nucleus and membrane bound organelles. Originally thought to be extremophiles living in harsh environments‚ these creatures can live a range of habitats like oceans‚ soils and even salty lakes. Overall‚ these organisms are special and different from other life forms. The rise of archae is one of the main differences why scientist distinct it from other prokaryotes. In the past‚ archae was classified an archaebacteria‚ but now with better

The Comparative Analysis of Simple Staining and Gram Staining Techniques by observing E. Coli and S. Pyogenes under the Compound Light Microscope INTRODUCTION: A German bacteriologist‚ Dr. Theodore von Escherich‚ was the first man in 1885 who discovered the bacterium named Escherichia coli‚ which are gram negative and appears in rod shaped. Most kind of bacteria E. Coli does not cause diseases and some strains indeed are beneficial in helping the process of food breaking down in the intestines

Methyl Red and Voges-Proskauer Test The Methyl Red test shows which bacteria are creating stable acids through mixed acid fermentation of glucose. This helps to identify enteric bacteria by examining how they metabolise glucose. Every enteric bacteria first produces pyruvic acid from metabolism of glucose. A methyl red positive enteric bacteria‚ uses the mixed acid pathway when breaking down pyruvic acid to different acids‚ like lactic‚ acetic‚ and formic acids. The Voges-Proskauer test determines
