Abstract

SUMMARY: The germination rate of spores and the manner in which it is influenced by pH, sodium ion concentration and temperature differ according to the organic germinant used. Only -alanine initiated germination when present alone. The germination rate with optimal -alanine was increased by -phenylalanine, -arginine, -histidine or -lysine but not by other common amino acids or -lactate. With suboptimal concentrations of -alanine, addition of -lactate, -arginine or -phenylalanine increased the germination rate more than an equal concentration of -alanine. The mechanisms whereby -phenylalanine and -arginine stimulate germination appear to be different from those involved when -alanine or -lactate are the germinants.
