Growth medium: You are running different experiments on microbes and need to make sure you choose the correct medium.

microbiology: Aseptic Culture Techniques Lab In your daily life, you utilize aseptic technique in order to minimize contamination. List five examples of ways in which you do this.

A medium in which all the components are known is: A. Minimal medium B. Synthetic or defined medium C. Selective medium D. Complete medium E. Complex medium F. Differential medium G. General purpose medium

A measurement of a microbe is reported as 1 × 10-6 m, also known as  centimeters (cm). millimeters (mm). nanometers (nm). yards. micrometers (μ m).

Sterility: is achieved by most disinfectants and antiseptics (i.e., chemical agents) O is achieved by soap and water is the absence of PATHOGENS or spoilage-causing microbes ONLY Cannot be achieved by ethylene oxide O CANNOT be achieved by autoclaving O is the absence of ALL living cells and endospores

When applying a disinfectant to kill microbes, our bead experiment showed that what two factors affect how effectively microbes will be killed?

microbial sensivity lab: in the procedure used to test bacterial growth against various temperatures (incubator, room, refrigerator, freezer), why should efforts be made to inoculate each tube with the same number of bacteria?

You are rotating sterile supplies based on the first in, first out (FIFO) principle. What would you look at? O Sterilization method Expiration date Manufacturing date Packaging material

Which of the following is a reason to run simultaneous tests on known positive and negative controls when identifying an unknown microbe using biochemical tests? The controls maintain the differential qualities of the test medium The controls can show if there was contamination of the tubes with another species The controls will ensure that the unknown microbe multiplies on the medium The controls can show if there was a recent mutation in your unknown microbe

Pick either of these media: (EMB or HE) and describe (again, in your own words) how the chemical ingredients in that medium work to make it both "selective" as well as "differential"
