Abstract

Ultraviolet (UV) resistance patterns of sporulating Bacillus cereus were determined. Six different categories of UV resistance were discernible as the organism progressed from exponential growth to the free, mature spore. Light microscope observations allowed the assignment of certain sporulation stages to specific UV resistance categories. Marked changes in UV resistance were associated with stages III, mid-IV, and post-IV of sporulation. Dipicolinic acid was shown to sensitize forespores to UV radiation. Mechanisms invoked to explain the different UV categories are discussed.

摘要

测定了蜡样芽孢杆菌形成芽孢过程中的紫外线（UV）抗性模式。随着该生物体从指数生长期发展到游离的成熟芽孢，可辨别出六种不同的紫外线抗性类别。光学显微镜观察使特定的芽孢形成阶段与特定的紫外线抗性类别相关联。紫外线抗性的显著变化与芽孢形成的III期、IV期中段和IV期后阶段有关。已证明吡啶二羧酸会使前芽孢对紫外线辐射敏感。文中讨论了解释不同紫外线类别的机制。
