INVOLVEMENT OF NEAR‐UV‐INDUCED SYNTHESIS OF SEROTONIN IN PHOTOPROTECTION AND IN POTENTIATION OF FAR‐UV LETHALITY IN THE YEAST CANDIDA GUILLIERMONDII

Abstract
Abstract— This paper considers mechanisms of near‐UV (334nm) induced photoprotection as well as potentiation of far‐UV (254 nm) lethality in Candida guilliermondii. Using exogenous precursors of serotonin, it appears that the above two mechanisms involve photoactivated synthesis of serotonin. It has been postulated that the serotonin effect could take place by binding to DNA.
