Abstract

Curran, Harold R. (U.S. Department of Agriculture, Washington, D.C.), and Michael J. Pallansch. Incipient germination in heavy suspensions of spores of Bacillus stearothermophilus at subminimal growth temperatures. J. Bacteriol. 86:911–918. 1963.—By use of spore (plate) counts and permeability to stain, labilization was followed periodically in heavy suspensions of washed Bacillus stearothermophilus 1518 spores incubated at different temperatures. Although vegetative proliferation did not occur below 38 C, incipient germination was rapid down to 20 C and much slower and incomplete at 14 C. Dilution of the suspension materially reduced the degree and rate of labilization. The degree of washing and use of deionized water had no appreciable influence upon early development of the spores. The results are discussed from the point of view of the possible origin and nature of the germination stimulant.
