Photoreactivation of ultraviolet radiation-induced DNA damage was examined in exponential-phase cells of six mesophilic species of the genus Bacillus. Under the experimental conditions used, it was observed that the laboratory strains B. cereus strain T and B. thuringiensis var. thuringiensis strain NRRL-B4039 exhibited strong photoreactivation (86-fold and 70-fold respectively). Bacillus licheniformis strain ATCC 8480 exhibited moderate (15-fold) photoreactivation. Weak photoreactivation was observed in B. subtilis strain 168 (4-fold) and B. megaterium strain QM B1551 (3.4-fold). Bacillus amyloliquefaciens strain H demonstrated no detectable photoreactivation.
在芽孢杆菌属的六种嗜温菌的指数生长期细胞中检测了紫外线诱导的DNA损伤的光复活作用。在所使用的实验条件下，观察到蜡样芽孢杆菌T菌株和苏云金芽孢杆菌苏云金变种NRRL-B4039实验室菌株表现出强烈的光复活作用（分别为86倍和70倍）。地衣芽孢杆菌ATCC 8480菌株表现出中等程度的（15倍）光复活作用。在枯草芽孢杆菌168菌株（4倍）和巨大芽孢杆菌QM B1551菌株（3.4倍）中观察到微弱的光复活作用。解淀粉芽孢杆菌H菌株未表现出可检测到的光复活作用。
