Effects of Mn2+ levels on the resistance properties of Bacillus cereus spores

  In some Bacillus species, manganese levels influence the resistance properties of spores. To determine if this was true for Bacillus cereus, bacteria were sporulated with different MnCl2 concentrations resulting in spores with 30-fold differences in core Mn2+ levels. Spores with different Mn2+ levels displayed no differences in resistance to dry heat, UV...
