What are yeast plates?
Plates are petri dishes with some the agar media poured in the bottom. They are generally used for reculturing or viability test rather than long-term storage. Pro: spacious area to work in. Can do quadrant streaking to isolate single-cell colonies. Con: easily contaminated, although the area is so large you can likely visually isolate yeast and replate it. Condensation can be hard to manage, and when there is no condensation the agar medium can quickly dry out. Should to be sealed with parafilm, electrical tape, or other water barrier. Usually has to be recultured in weeks. Sterility/starter/refrigeration required.
