1. Analysis of photosynthetic pigments and phenolic compounds in Gracilariopsis tenuifrons (C.J. Bird &E.C. Oliveira) Fredericq &Hommersand at different light intensities / Análise de pigmentos fotossintetizantes e substâncias fenólicas em Gracilariopsis tenuifrons (C. J. Bird &E. C. Oliveira) Fredericq &Hommersand em diferentes intensidades de luz
The high-light stress can adversely affect growth and development of photosyn-thetic organisms. In these situations, it is common to note chemical responses that may indicate different strategies of photoprotection. In this study, protocols were optimized for analysis and extraction of phenolic compounds and photosynthetic pig-ments in macrophytic red algae

2. The diversity, extracellular enzymatic activities and photoprotective compounds of yeasts isolated in Antarctica
The diversity of yeasts collected from different sites in Antarctica (Admiralty Bay, King George Island and Port Foster Bay and Deception Island) and their ability to produce extracellular enzymes and mycosporines were studied. Samples were collected during the austral summer season, between November 2006 and January 2007, from the rhizosphere of Deschampsia

3. Análogos de micosporinas: síntese e avaliação de parâmetros farmacológicos e toxicológicos / Mycosporines analogues: synthesis and evaluation of pharmacological and toxicological parameters.
Micosporinas são substâncias pertencentes a um grupo de compostos naturalmente encontrados em algas e fungos, que são utilizadas por estes organismos como mecanismo de defesa. São potentes bloqueadores químicos de radiação ultravioleta (UV), atuando principalmente na faixa espectral da radiação UVA, com absorção máxima variando entre 300 e 360 nm
