Purpose: Unknown mixtures will be separated by means of chromatography in which the mixture will be passed in a solution through a medium leaving behind components of the mixture at different rates‚ therefore‚ different spots on the absorbing substance. This will help determine the identity of unknown mixtures. The spot colors on the strip of filter paper and the Rf values of the unknown samples will be compared to those of known samples. To find the position of the spots on the strip of paper‚ we

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

The first test conducted on unknown bacteria 32 was the Gram stain. From this stain‚ unknown 32 was found to be a Gram-positive cocci. This test eliminated all possible Gram-negative bacteria‚ Gram-positive rods and Gram-positive spirillium. Next‚ the endospore test determined whether or not the Gram-positive bacteria contained endospores. With the use of malachite green‚ steam‚ and safranin it was found that unknown bacteria 32 did not contain endospores. This eliminated Gram-positive cocci Sporosarcina
