1. Caracterização dos resíduos esgotados de sistemas de tratamento individual de esgotos de Natal
In Natal still dominates the use of individual disposal systems for domestic sewage, once only 29% of the city has a sewarage system. Wastes that are accumulated in these individual treatment systems should be exhausted periodically, service provided by collector entrepreneurs. Some of these companies causing major damage to the environment. In Natal, only t

2. Acumulação de Poluentes Inorgânicos por Macrófitas Aquáticas nos Reservatórios de Santana e Vigário, Barra do Piraí-RJ / Accumulation of Pollutant Inorganic for Aquatic Macrophytes in Santana and Vigario Reservoir, Barra do Pirai-RJ
Paraíba do Sul River (1,145 km long) crosses three of the most important and developed states of Brazil: Minas Gerais, São Paulo and Rio de Janeiro. It is the main water supply for more than 11 million people in Rio de Janeiro City, and it is also used extensively as a waste disposal system by industrial facilities in all three states. Moreover it receives

3. Glyphosate degradation by immobilized bacteria: field studies with industrial wastewater effluent.
Immobilized bacteria have been shown in the laboratory to effectively remove glyphosate from wastewater effluent discharged from an activated sludge treatment system. Bacterial consortia in lab columns maintained a 99% glyphosate-degrading activity (GDA) at a hydraulic residence time of less than 20 min. In this study, a pilot plant (capacity, 45 liters/min)

4. In Situ, Real-Time Catabolic Gene Expression: Extraction and Characterization of Naphthalene Dioxygenase mRNA Transcripts from Groundwater
We developed procedures for isolating and characterizing in situ-transcribed mRNA from groundwater microorganisms catabolizing naphthalene at a coal tar waste-contaminated site. Groundwater was pumped through 0.22-μm-pore-size filters, which were then frozen in dry ice-ethanol. RNA was extracted from the frozen filters by boiling sodium dodecyl sulfate lysi
