Various tests were performed to provide the fermentation abilities‚ presence of particular enzymes‚ and biochemical reactions. Qualitative observations were made on the tests in identification process. The data from experimentation provided sufficient results to suggest that the identity of unknown bacterium

identify unknown bacteria cultures using various differential tests‚ and my unknown bacteria is #17. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures. The differential tests used to identify the unknown cultures

NOTE: As you read the information in the Microbiology Handbook‚ there may be some terms you are not familiar with – such as 16s ribosomal RNA and Polymerase Chain Reaction. Refer to your text to read background material explaining any terms or processes with which you are not familiar. Record the results of your investigations of each unknown in Table 1 by completing the following steps: 1) Apply the stain to your first unknown slide and examine it under the microscope. 2)

results were ambiguous. Without putting the slide into the microscope‚ I noticed one was pink and the other purple. To resolve it‚ I discarded my slides and started again and was extremely careful in proceeding the Gram Stain. I concluded that my unknown A was gram-negative bacilli. Using the dichotomous key for gram-negative bacilli I started the protocol for the lactose test2 which would help me determine which test to conduct next to narrow down list of possible bacteria. I conducted the protocol

To do this‚ following instructions on page 104 in the Microbiology Lab Manual‚ molten agarose was poured into a casting tray where it remained for solidification. Once solidified‚ 300 ml of a buffer was added‚ this is so the electrical field has something to pass through. Next‚ each person pipetted 5 microliters

Rheumatoid arthritis is thought to be caused by a combination of genetic and environmental factors but at the present time there is no known cause of RA. Although‚ a definite cause is unknown‚ there are several known risk factors some which are considered modifiable (CDC‚ 2012). These include: family history‚ age‚ gender‚ reproductive/breastfeeding history and smoking. Doctors and specialist believe that a family history of

Unknown Experiment Introduction: The purpose of this experiment is to distinguish and indentify an unknown bacterium. There are several tests that can help one eliminate and narrow down the options. The most useful test‚ and the very first one done‚ is a gram stain. This test will tell whether the bacterium is gram-positive or gram-negative. After the type of gram stain is identified‚ the tester has a wide array of differentiating tests at their disposal. Based on the results from these
