title: Photoprotection by dipicolinate against inactivation of bacterial spores with ultraviolet light.
abstract: The resistance of three types of Bacillus cereus T spores to ultraviolet radiation corresponded to their dipicolinic acid (DPA) content. Photoprotection against ultraviolet light was observed in DPA-containing spores and in DPA-less spores irradiated through calcium dipicolinate.
