Question

Condensation often gathers in the bottom of agar slants. why is it important in this exercise to limit condensation on plates but not on slant

Answer 1

Because condensation on the slant effects the bacterial growth in the test tube.

Step-by-step explanation:

• When agar is solidify in the test tube tilted, it takes a shape of slide on one side of the tube which is known as slat.
• Slant is used instead of petri dishes because they provide more surface area for growth.
• Water in the slat can invade the test tube, making agar unstable and the bacterial growth on the slat will be affected by moisture in bottom of slant.
• In petri dishes, it is no big problem of moisture condensation.
