Optimal pH of the germination at 25 C and 37 C was neutral, while at lower temperature such as 6 C and 14 C it shifted to acid side, pH 5.0. Glycine (at 100 mM), L-cysteine (at 100 mM) and Hg^{2+} (at 10 mM) inhibited the alanineinduced germination remarkably. Effects of chemical treatments on spores varied with the conditions of treatments. Treatments of spores with 0.1 N NaOH at 80 C, 0.1 N HCl at 60 C, 5% sodium lauryl sulfate (SLS) at 60 C and 5% phenol at 60 C broke the capacity of germination completely. The spores by treatment with NaOH at 40 C and SLS at 60 C became lysozyme-sensitive. Treatment with NaOH at 60 C decreased the germination rates, failed to induce histidase during outgrowth and made the spores sensitive to lysozyme but it had little effect on viability and heat resistance.}, pages = {139--147}, title = {Factors affecting the germination of Bacillus subtilis spores}, volume = {24}, year = {} }
