Bdellovibrio underwent photooxidation by visible light in the presence of exogenous photosensitizer and by near-ultraviolet light (325 to 400 nm) in its absence. The colorless, host-dependent wild type was more sensitive to the lethal effect of light than was its pigmented, facultative parasitic mutant. The latter's ability to form colonies was much more sensitive to light than was its plaque-forming capability. The biosynthesis of the mutant pigment was inhibited by diphenylamine, though this inhibition did not result in additional sensitivity to photokilling.
在存在外源性光敏剂的情况下,蛭弧菌可被可见光进行光氧化,而在没有外源性光敏剂时,可被近紫外光(325至400纳米)进行光氧化。无色的、依赖宿主的野生型比其有色素的兼性寄生突变体对光的致死效应更敏感。后者形成菌落的能力比其形成噬菌斑的能力对光更敏感。二苯胺可抑制突变体色素的生物合成,尽管这种抑制并未导致对光杀伤的额外敏感性。
