Germination properties of spores with low dipicolinic acid content

A KEYNAN et al. J Bacteriol. 1962 Feb.

Abstract

Keynan, A. (University of Wisconsin, Madison), W. G. Murrell, and H. O. Halvorson. Germination properties of spores with low dipicolinic acid content. J. Bacteriol. 83:395-399. 1962.-When the dipicolinic acid content of spores of Bacillus cereus strain T is reduced from 7.5 to 2 or 3%, the spores germinate spontaneously after heat activation and are sluggish in their response to l-alanine and other germination agents. Only germination initiated by calcium dipicolinic acid is unaffected. l-Alanine-induced germination is stimulated by exogenous dipicolinic acid. These results support the hypothesis that endogenous dipicolinic acid regulates the l-alanine-triggered germination.
