What is the purpose of using the streak plate method? - ANSWERStreak
plates lead a scientist toward a pure culture for identification or examination
of a single bacterial strain
The goal of streaking for isolation is to spread an inoculum of bacteria thinner
and thinner with each pass for the identification of individual colony-forming
units. What action must be performed between each step to ensure this? -
ANSWERSterilization of the loop must be performed
Partially digested yeast, which has varying chemical elements, is added to a
medium that has been created with exactly measured ingredients. What type
of media has been produced? - ANSWERcomplex media
A medium designed to change color in order to indicate growth of certain
types of bacteria would be considered a __________ - ANSWERdifferential
medium
Why might a hospital choose to use transport media to carry clinical
specimens? - ANSWERTransport media are designed to keep microbes stable
until they can be inoculated into appropriate growth media
Because some target bacterial species are out-competed by others during
growth on media, it is sometimes necessary to inhibit the growth of the
