Purpose: To identify an unknown bacterial specimen using basic laboratory technique and biochemical tests. The unknown bacteria will be one of the following: Enterococcus faecalis‚ Staphylococcus saprophyticus‚ Escherichia coli‚ Enterobacter aerogenes‚ Proteus vulgaris‚ Salmonella [I assume typhimurium]‚ or Shigella [either flexneri or sonnei‚ we used both in our lab during the semester]. Procedure {and observations}: Observe bacterial colony morphology. {Colonies are large‚ beige or

The unknown bacteria A and bacteria B have to be identified by its genus and species. First both bacteria had to be inoculated into a TSA agar media using the streak plate method. Four quadrants were drawn‚ so that the bacteria could be isolated as much as possible. Each bacteria was inoculated into two different plates‚ so that one could be incubated at 37 degrees Celsius and the other at 25 degrees Celsius. Bacteria B‚ which was incubated at room temperature showed red colonies throughout its media

was aimed to complete the goal of answering questions about the system of three unknown red solutions. Based on the experiments conducted and the data collected‚ I am able to conclude information about the three red solutions that will lead to a possible identity of each red solution. Starting with red solution #1‚ we are able to conclude that there are no nanoparticles in this solution and that is a molecular compound due to the fact that when potassium iodide was added‚ there was no color change
