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.
摘要
三种蜡样芽孢杆菌T型芽孢对紫外线辐射的抗性与其吡啶二羧酸（DPA）含量相对应。在含DPA的芽孢以及通过吡啶二羧酸钙辐照的无DPA芽孢中均观察到了对紫外线的光保护作用。
