*If you don't want to flame, drop a stirbar into the flask before autoclaving. Mix on the stirplate to add sugar and aa's, stir some more to take care of bubbles. Pour carefully. -Travis | *If you don't want to flame, drop a stirbar into the flask before autoclaving. Mix on the stirplate to add sugar and aa's, stir some more to take care of bubbles.

*Plate thickness varies greatly depending on who pours the plates. I prefer thicker plates (500mL = 24 plates) rather than thinner plates (500mL = 40+ plates). In my experience, thin plates can dry out before the yeast colonies reach their full growth (so you end up with small colonies and thin streaks). This is particularly problematic for slow-growing strains. -Josh | *An additional bubble-reducing strategy is to use the 70% ethanol spray mist bottle to spray a single mist of ethanol into the flask after mixing in the sugar and aa's but before pouring the plates. Be careful if you flame the flask after spraying, as the ethanol can ignite and send a mini flame shooting out of the flask. -Mike | ||
