Title: GERMINATION PROPERTIES OF SPORES WITH LOW DIPICOLINIC ACID CONTENT
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.
