that will be of use to you throughout your biological work. Procedure 1. Heat the test tubes of sterile agar medium in the water bath until the agar melts. 2. Remove the test tubes from the water bath. Let them cool enough to hold in your hand‚ but not so much that the agar becomes solid again. Perform the following transfer as quickly as possible. You must work rapidly so that the liquid agar will not cool and solidify before the transfer is completed. 3. Hold both a test tube

Significance: Understand the use of Mannitol salt agar‚ blood agar and MacConkey agar plates which must be used based on the components of the bacteria. The catalase test will be used to understand the difference in facultative anaerobic and groam positive from aero tolerant anaerobes. The coagulase test converts fibrogen

semi-permeable outer membrane of E. coli would protect the bacteria from any antimicrobial properties of cilantro. A drop of cilantro juice and water in varying concentrations (1:10‚ 1:20‚ 1:40‚ 1:80) was added to a nutrient agar plate inoculated with S. epidermis and a nutrient agar plate inoculated with E. coli. The plates were incubated for 48 hours and then observed for a zone of clearing where the cilantro juice drop was placed. Cilantro was found to not display antimicrobial activity against either
