Abstract
The entire absorbance vs. time curve of a sample of germinating bacterial spores can be accurately described by a model which considers that the spores rate of entry into the phase initiation of germination is determined by transitions between three spore states. The first of these transitions is easily identified with the triggering event, while the existence of the intermidiate state, and its identification with the triggered spore, can be established from theoretical as well as experimental considerations. The observed sample lag time is seen to arise from the position of the measured event in the single spore in the sequence of indices of germination. Consideration that the single spore may effect the measured change in a complex way over a finite interval of time leads to a mathematical formulation of our model which can describe the germination process whatever the endpoint chosen for its observation.
