Agar plate

Another way of plating organisms next to streaking on agar plates is the spot analysis This type of analysis is often used to check the viability of cells and performed with pinners (often also called froggers) A third used technique is the use of sterile glass beads to plate out cells In this technique cells are grown in a liquid culture of which a small volume is pipetted on the agar

Mold Sampling: How To Select Agar Media

The problem of using a single type of media is that some molds may not grow well (or may not grow at all) in the selected media Hence although such molds may be the dominant contaminants in the air they may end up being missed or underestimated The solution therefore is to use more than one type of mold sampling media or select one that is known to support a wide range of environmental
