Why are growth characteristics more valuable on agar plates than they are?
Why are growth characteristics better on agar plates and not on agar slopes? Because they can be capped to prevent the agar from drying out, slants are more suitable. Caps also prevent airborne contaminants from entering the slant. Slants require less storage space.
What factors besides physical growth characteristics are important when recording?
What factors, other than physical growth characteristics, are important in recording data about an organism’s biology? You should also include the growth medium, incubation temperatures and atmosphere (aerobic/anaerobic).
Why is agar slant useful?
Agar Slants can be used for culture of bacterial cells to identify them. It is hard to identify bacteria in large samples because they are often small and difficult to find. In maintaining bacteria cultures, agar slants can be more useful than Petri dishes.
What is an agar deep used for?
Agardeeps are used for growing bacteria that requires less oxygen than what is available on the medium’s surface. They are also used to determine the oxygen requirements and mottle of bacteria. Motile bacteria can grow/move away from the point where they were inoculated.
What is the primary use of slants and why?
Micro Lab 4
|What is the primary use of slants?||Long-term storage. Pure cultures|
|What is the primary use of deeps?||To store anaerobic bacteria. To test oxygen requirements.|
|What is the primary use of broths?||To grow large amounts of bacteria.|
What is the purpose of heating the loop before use?
What is the purpose for flaming the loop prior to use? After use? Flamming your culture before it is used kills any bacteria that may be on the loop. Flamming after use kills bacteria that may have been transferred through your bacterial transfer activities.
