Release of Small Molecules during Germination of Spores of Bacillus Species

Department of Molecular, Microbial and Structural Biology, University of Connecticut Health Center, Farmington, Connecticut 06030-3305

Received 20 March 2008/ Accepted 26 April 2008

Free amino acids, dipicolinic acid, and unidentified small molecules were released early in Bacillus spore germination before hydrolysis of the peptidoglycan cortex, but adenine nucleotides and 3-phosphoglycerate were not. These results indicate that early in germination there is a major selective change in the permeability of the spore's inner membrane.
