performed this test‚ the initially slant for unknown microorganism #17 is important. For this lab‚ two identical slants are used for two reasons. Firstly‚ the slant can be used to make sure that there is no contamination from the Nutrient Agar plate. Secondly‚ the second slant will become a stock culture to prevent the shortage of slants during performing the series of tests. Kliger’s Iron Agar tests can be used to determine multiple characteristics of unknown microorganism #17. Kliger’s Iron Agar slants

Microbiology Laboratory Report Identification of Unknown Bacteria 03/10/05- 04/01/05 Authors: Richard Hendricks‚ Jessica Prebish; NMU Abstract: Broth culture 16 was randomly selected by our group and subjected to qualitative tests for taxonomic identification. The culture did appear homogenous throughout the testing period and is currently retained by Northern Michigan University’s department of Microbiology. We suggest that culture 16 is an example of Escherichia coli. Background: Techniques

Requirements for Unknown Report You have been provided a mixed culture (a gram positive and a gram negative) from which you should have isolated each type of organism‚ described their colonies on a TSA plate‚ and described their cellular morphology. You were graded on this activity separately. After you have isolated your gram negative in pure culture you will be subjecting it to various biochemical tests and making observations about the cells‚ colonies‚ growth temperature preferences‚ etc. in

Biology 205 MW 2:10pm. Unknown Organism Paper The unknown organism tested in the Mesa lab was collected from in between the toes of my puppy‚ Riley. The original culture grown consisted of dozens of visibly different organisms of varying colony colors and growth patterns. I chose to test a smaller‚ red colony for my experiments. Based on its gram reaction and oxygen requirements‚ the following tests were performed to reach my presumptive ID: Test Performed Result Gram Stain + Fluid Thioglycollate

The unknown soda ash from experiment 3 was used‚ to determine the weight for each trial we used the equation of (M of HCl) x (18 ml x 105.99) / (10 x 2 x Na2CO3 ). Which was equal to (0.01472 M) x ((18 mL X 105.99)(10 x 2 X 2.428 % )= 0.6 g. To start we had to rinse the beakers‚ electrode and the stirring bar with diluted water. The sample we needed was weighted to the closest 0.1 mg which we got was 0.3 for the first trial. The sample was transferred to a 250 mL beaker and dissolved in 70 mL of
