Germination in subgerminative concentrations of alanine or inosine in combination with amino acid adjuncts. (A) Germination of spores of B. cereus ATCC 10876, the Ger+ parental strain, in l-alanine (20 μM) plus other amino acids. Symbols: □, no addition; ○, 10 mM histidine; ▵, 10 mM proline; ▴, 1 mM tyrosine; •, 10 mM tryptophan. (B) Germination of spores of B. cereus ATCC 10876, the Ger+ parental strain, in 40 μM inosine plus amino acids. Symbols are as in panel A: □, no addition; ○, 10 mM histidine; ▵, 10 mM proline; ▴, 1 mM tyrosine; •, 10 mM tryptophan. (C) Germination of mutants in inosine (40 μM) plus tryptophan (10 mM). Symbols: ○, B. cereus ATCC 10876, the Ger+ parental strain; ⋄, gerL; ▴, gerT. These three graphs are superimposed and demonstrate complete germination. The following graphs showed little or no germination and are largely superimposed: •, gerQ; ▵, gerI; □, gerN.
