Microbiology Lab Exam 6 Questions with Complete Solutions rated A+
How are thermal death point and thermal death time different? - Thermal death point is the lowest temperature that kills all cells in a broth in 10 minutes. Thermal death time is the time required to completely sterilize a particular volume of liquid at a given temperature. Is moist heat more effective than dry heat? - Because of its ability to penetrate microbial cells, moist heat kills microogranisms by denaturing their proteins. Sterilization can be achieved at lower temperatures in a sh...

Describe the selective and differential properties of mannitol salt agar (MSA) for the isolation and identification of staphylococci. - As a selective medium, MSA has a high concentration of salt (7.5% NaCl), which is inhibitory to most bacteria other than the staphylococci. As a differential medium, MSA contains the sugar mannitol as a substrate for fermentation and phenol red as a pH indicator to detect the production of acid. S. aureus ferments mannitol and changes the color of the mediu...
