Résumé
To investigate effects of the cationic surfactant cetyltrimethylammonium bromide (CTAB), a disinfectant, on spores of Bacillus species. The ability of CTAB to trigger release of Bacillus spores' large depot of dipicolinic acid (DPA) in a 1 : 1 chelate with Ca The results of this investigation showed that CTAB kills spores of three Bacillus species, perhaps by damaging the spore inner membrane, although it is also possible that some killing by this agent follows its triggering of spore germination. The results of this work indicate that CTAB is also a disinfectant, but also a sporicide, and may be a useful adjunct in spore decontamination, especially at higher temperatures.
