Microorganisms are classified according to their structure. By means of flow charts‚ diagrams and tables explain the differences between Viruses‚ Bacteria‚ Cyanobacteria‚ Achaea and Fungi. Bacteria or bacterium are unicellular microorganisms. They are essentially only a few micrometres long and form of various shapes including the spheres‚ rods and spirals.

Alyse Rose Microbiology Lab Bacterial Unknown March 25‚ 2013 Bacterial Unknown Report Each student was given an unknown bacteria to figure out. I was given the unknown bacteria S38. Everybody is supposed to do all sorts of test to identify the bacteria. The first thing I did was smear my bacteria on a liquid medium. I then proceeded to incubate the medium for 24-48 hours. 1. GRAM STAIN The next step I took in finding my unknown bacteria was to gram stain it. This is used to differentiate

Pure Culture Techniques In this first lab‚ you will be learning some very fundamental and important techniques. As is the case with most things‚ shorts cuts usually get you in trouble. This is especially true in Microbiology. The techniques you will be learning tonight‚ if mastered correctly‚ will make your life and learning experience in Microbiology much easier‚ if you don’t pay attention and practice these techniques incorrectly‚ well then……? Today you will be learning the following techniques:

For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

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
