1. Eunotiales (divisão bacillariophyta) perifíticas de algumas localidades da bacia hidrográfica do Rio Descoberto, Distrito Federal - Goiás, Brasil / Periphytic eunotiales (Bacillariophyta division) from several points of the hydrographic basin of the Descoberto river, Federal District - Goiás, Brazil
A pioneer taxonomic survey of the Eunotiales (Bacillariophyta) from the Descoberto River and some of its tributaries is the aim of this study. In general, few taxonomic studies of diatoms have been done in the Federal District (DF) and Goiás State, Brazil. The Descoberto river basin, where the rivers that form the study area are located, is the main hydric

2. Polissacarídeos extracelulares e atividade enzimática das glicosidases no reservatório de Barra Bonita, SP, Brasil.
Release of extracellular polysaccharides can occur from healthy and active cells and has been demonstrated to be an important carbon source for bacteria. In eutrophic environments where large blooms are formed by efficient extracellular polysaccharide producers such as Microcystis aeruginosa and Anabaena spiroides, these organic materials (high molecular wei

3. Produção de TEP (Transparent Exopolymer Particles) em culturas de três espécies de microalgas isoladas do reservatório de Barra Bonita (Rio Tietê/SP)
Transparent exopolymer particles (TEP) have recently been documented to be abundant in ocean waters and in algal cultures. TEP play important roles in the ecology of aquatic ecosystems since they might be a direct source of carbon for higher trophic levels via protists and microzooplankton. They also adsorb dissolved compounds and compose the matrix of marin
