FIG. 2.

Germination of spores over long periods on solid medium. Approximately 50 wild-type strain PS832 spores (solid bars) or 5,000 mutant strain FB85 spores (shaded bars) were spread on 15-cm LB agar plates and incubated at 37°C for 8 days. The number of new colonies that appeared every 24 h was recorded and expressed as a percentage of the total number of colonies recovered over the 8 days of the experiment (33 wild-type colonies and 14 mutant colonies). Similar data were obtained with two different batches of spores.
