1. Avaliação da atividade microbiana metanogênica na lagoa de estabilização anaeróbia da estação de tratamento de esgotos sanitários do município de Cajati, Vale do Ribeira do Iguape, Estado de São Paulo / Assessment of anaerobic methanogenic microbial activity at anaerobic stabilization pond of domestic wastewater plant at Cajati city, Vale do Ribeira de Iguape, São Paulo State, Brazil
Microbial diversity studies have remarkable relevance since the knowledge about the microbiology of process can improve plants and system efficiency. This work assessed microbial activity, specially methanogenic, at anaerobic pond for domestic wastewater treatment in the city of Cajati, São Paulo State, Brazil. Poliphasic taxonomy was adopted in onder to co

2. Estrutura da comunidade microbiana (algas e bactérias) em um sistema de lagoas de estabilização em duas escalas temporais: nictemeral e sazonal / Microbial structure (algae and bacteria) from a wastewater stabilization ponds system in two different temporal scale: nictemeral and seasonal
The study of the microbial community (algae and bacteria) that participates of the organic matter stabilization process in the effluent sanitary it is important for the best knowledge of the types of the biological treatment systems. The evaluation of the dynamics of the algae and bacteria in the Australian wastewater stabilization ponds of the Novo Horizont

3. Especificidade em associações alga/bactéria vinculadas aos carbidratos excretados por três espécies fitoplanctônicas de um reservatório tropical eutrófico do Estado de São Paulo (Barra Bonita).
The release of carbohydrates by phytoplankton has been extensively studied because of its ecological significance. Bacterioplankton is a group of organisms that is able to use extracellular phytoplanktonic carbohydrates, as many authors have demonstrated. The aim of this thesis was to identify specific associations algae/bacteria in the planktonic environmen

4. Effects of microbial community interactions on transformation rates of xenobiotic chemicals.
The effects of culture filtrates, mixed populations, and common microbial exudates on bacterial transformations of three agricultural and industrial chemicals were investigated. Test chemicals included methyl parathion, diethyl phthalate, and 2,4-dichlorophenoxyacetic acid butoxyethyl ester. The presence of various cultures, filtrates, or exudates of algae,

5. Microbial Dynamics of an Epilithic Mat Community in a High Alpine Stream
Studies were conducted to examine interrelationships between the heterotrophic and phototrophic populations within an epilithic community in the outlet stream of a high alpine lake. Levels of nitrates, phosphates, and total organic compounds in the lake were consistently near the lower limits of detectability. Microscopic examination of the community by phas

6. Virioplankton: Viruses in Aquatic Ecosystems†
The discovery that viruses may be the most abundant organisms in natural waters, surpassing the number of bacteria by an order of magnitude, has inspired a resurgence of interest in viruses in the aquatic environment. Surprisingly little was known of the interaction of viruses and their hosts in nature. In the decade since the reports of extraordinarily larg

7. Metabolically Active Eukaryotic Communities in Extremely Acidic Mine Drainage
Acid mine drainage (AMD) microbial communities contain microbial eukaryotes (both fungi and protists) that confer a biofilm structure and impact the abundance of bacteria and archaea and the community composition via grazing and other mechanisms. Since prokaryotes impact iron oxidation rates and thus regulate AMD generation rates, it is important to analyze

8. Distribution of bacterioplankton in meromictic Lake Saelenvannet, as determined by denaturing gradient gel electrophoresis of PCR-amplified gene fragments coding for 16S rRNA.
The community structure of bacterioplankton in meromictic Lake Saelenvannet was examined by PCR amplification of the V3 region of 16S rRNA from microbial communities recovered from various depths in the water column. Two different primer sets were used, one for amplification of DNA from the domain Bacteria and another specific for DNA from the domain Archaea
