FIG. 1.

Growth of yeast cells in microwell plates as determined by monitoring OD₆₃₀. Yeast cells were seeded into microplate wells and transferred to an incubator at 30°C as described in Materials and Methods. The OD₆₃₀ was measured at 3- to 4-h intervals until significant increases were seen. The plate was then transferred to the reader at 30°C, and readings were taken hourly for 17 h. To conserve lamp time, readings were then taken at 2- to 5-h intervals.
