ABSTRACT

The structural specificity required for induction of germination of spores of Bacillus stearothermophilus by analogues of dipicolinate in buffer at pH 5.5 is similar to that found previously with spores of Bacillus megaterium and calcium chelate salts at pH 8. 4H-pyran-2,6-dicarboxylate, but no other analogue tested, is as effective as dipicolinate di-anion.
