Lethal, mutagenic and recombonogenic action of the solar radiation on the model microorganisms--phage T4, bacteria Escherichia coli and ascomycet Aspergillus nidulans--has been studied. A considerable lethal effect of the solar radiation on phage T4 and E. coli was found. An increasing of mutation frequency in E. coli and A. nidulans by sunlight was also revealed. Recombinogenic action of solar radiation has been demonstrated in the experiments with diploid A. nidulans strains. It was shown that the excision and postreplication repair systems took part in recovery of damages induced by sunlight. An important role of ultra-violet region (280-320 nm) solar radiation in induction of lethal and mutagenic effects was demonstrated for all investigated microorganisms.
研究了太阳辐射对模型微生物——噬菌体T4、大肠杆菌和子囊菌烟曲霉的致死、诱变和重组作用。发现太阳辐射对噬菌体T4和大肠杆菌有相当大的致死作用。还揭示了阳光可增加大肠杆菌和烟曲霉的突变频率。在二倍体烟曲霉菌株的实验中证明了太阳辐射的重组作用。结果表明，切除修复和复制后修复系统参与了对阳光诱导损伤的修复。对于所有研究的微生物，都证明了紫外线区域（280 - 320纳米）的太阳辐射在诱导致死和诱变效应方面的重要作用。
