Virtual unknown microbiology labs are a common way for students to learn about the identification of microorganisms. In these labs, students are given a sample of an unknown microorganism and are tasked with identifying it through a series of tests and observations. These labs can be conducted in a physical laboratory setting or through a virtual platform, which allows for flexibility and convenience for students.
There are several steps that students can follow to identify their unknown microorganism in a virtual unknown microbiology lab. The first step is to determine the physical characteristics of the microorganism, such as its shape, size, and arrangement. This can be done through the use of a microscope, which allows students to observe the microorganism at a higher magnification.
The next step is to perform biochemical tests to identify the metabolic capabilities of the microorganism. These tests can include determining the ability of the microorganism to ferment sugars, produce certain enzymes, or utilize specific nutrients. By performing a series of these tests, students can narrow down the possible identities of their unknown microorganism.
Another important step in the identification process is to consider the environmental conditions that the microorganism was isolated from. For example, some microorganisms are found in soil, while others are found in water or in the human body. By considering the environmental context, students can further narrow down the possible identities of their unknown microorganism.
Ultimately, the goal of a virtual unknown microbiology lab is for students to learn about the identification of microorganisms and to gain an understanding of the diversity of microbial life. By following these steps and using the resources available to them, students can successfully identify their unknown microorganism and gain a deeper understanding of microbiology.

The combination of SXT sensitivity increases the accuracy of the results. The carbohydrate fermentation test is used to determinewhether or not bacteria can ferment a specific carbohydrate. Four main families with numerous genera and species comprise the Gram negative enteric: Enterobacteriacea, Pseuodmonadaceae, Vibrionaceae, and Camplyobacteraceae. Maybe your local college has a micro tutor, using wikipedia to look up stuff in micro can get kinda overwhelming since it goes into way too much detail for tests. Refer to your Atlas as necessary for additional information if needed. I'm resurrecting this thread because I'm having problems with it, too. The tests performed and what constitutes a positive and negative test are as follows.
Final Lab report of BIO 265 Unknown microbe experiment
Currently, the most effective way of identifying the taxonomy and phylogeny of an unknown bacterium relies on the use of 16S rRNA gene sequences, which is a common genetic marker present in almost all bacteria Janda, Abbott 2007. Results You can differentiate four types of hemolysis by the appearance of the agar. To confirm the identity of sample A, the BEA, nitrate and MR tests were performed. This simulation also allows many students to learn lab techniques that would require a lot of time and resources. It features a new look, more structure for teaching microbiology, and a new collection of activities and resources for students and instructors…all centered around its tried and true simulation. Once a pure sample was confirmed by gram stain the two pure samples were used to inoculate a Nutrient slant labeled Gram-positive, and Gram-negative in order to grow pure samples of the two organisms.

In 2023, VUMIE Online becomes the latest version of this award winning software. Test Brief Instructions Probable Results TSA General Maintenance Media for Staphs Determine macromorphology Gram Stain To confirm culture purity Staphs are Gram positive McFarland Standard Dilute your organism in a tube of sterile water to obtain a turbidity equivalent to a 0. Tools include using a pH meter, aerobic plate count, High-Temperature Short-Time Treatment HTST pasteurization, and canning. Organisms which produce catalase will bubble when placed into hydrogen peroxide. The fermentation of dextrose glucose results in the production of acid. I don't understand how to run multiple tests on a sample.

See probable results table 4 below. Second , after completing the Pre-Lab questions, you will complete an assigned exercise where you will identify an unknown microorganism based on the test result images provided. Salt Tolerance Lightly inoculate broth. Different items on the workbench, collected from the fieldwork, are also fun to interact with. If an organism is able to ferment the carbohydrate, there will be acid produced, which will turn the broth yellow. You will do this virtually via your computer in these 2 steps.
