[Repair of damage caused by 313 nm light and photoprotection in Candida guilliermondii].
The study of the effect of near-UV light (300-380 nm) on the yeast Candida guilliermondii has shown that certain doses of 313 nm light cause inactivation which is reversible after the cells have been kept for some time in a non-nutrient medium. The findings suggest a different nature of the lesions resulting in killing the cells irradiated with light of 313 and 254 nm. The data obtained are interpreted in terms of a new, yet unknown, repair mechanism, other than the classical dark reparation, which is involved in the recovery of cells inactivated by light of 313 nm. Non-lethal doses at 313 nm induce photoprotection of the cells against UV lesions. The effect was compared with the photoprotection described in literature, and was found to be different.
