FIG. 3.

Dependence of the rate of germination of gerBB* spores on the concentrations of various amino acids. Spores of strain PS3665 (has only GerBB*) were heat shocked and germinated with various concentrations of different amino acids, and the rates of spore germination were determined as described in Materials and Methods. Maximum rates of spore germination were taken as those at 10 mM amino acid. The symbols for the amino acids used are as follows: ○, l-alanine; •, l-asparagine; ▪, l-serine; ▴, d-alanine; □, glycine; and ▾, l-threonine.
