Abstract

Ultraviolet radiation causes several harmful effects to living organisms,especially in the human epidermis, where lesions can culminate in skin cancer.skin. The existing alternatives to avoid or delay these impacts on the skin areartificial synthetic sunscreens, which are toxic because they have potentialcarcinogenic and neurotoxic in humans. In addition, they are cytotoxic and accumulatein organisms of aquatic ecosystems. Biomolecules produced by algae,cyanobacteria and fungi, known as mycosporins and amino acids likemycosporins, are capable of converting UV radiation into heat, therefore, they can composean alternative sunscreen with low or no toxicity. The Laboratory ofMicrobial Interactions at the Federal University of São Paulo, has been dedicated tocollect yeasts that have the ability to carry out the biosynthesis ofmycosporins. Currently, 3 mycosporin-producing isolates have been assembled,they are: 2 isolates of Papiliotrema laurentii, and one isolate of Naganishiafriedmannii. The production of mycosporins by these isolates was confirmed byour research group, as well as micromorphological characterization and certificationthat they have low pathogenic potential. With that, the objective of thiswork is to carry out genotypic and phenotypic characterization of the isolate producingmycosporins N. friedmanni, regarding the production of these molecules. will beqPCR techniques were employed, serial dilution in different culture media,induction of mycosporin production, bioinformatics analysis, sequencingof Sanger and UHPLC-HRMS (Ultra High Performance Liquid Chromatography - HighResolution Mass Spectrometry).
