1. AvaliaÃÃo fÃsico-quÃmica da remediaÃÃo de solos contaminados por BTEX
This research had as objective to evaluate the efficiency of the reactive means in the removal of aromatical hydrocarbons BTEX (Benzene, Toluene, Etil Benzene and Xylenes) in the ground, coming of leak of gasoline, either in fuel stations or underground tanks, and to explain the physico-chemical mechanisms that occuring on the system. The experiment was carr

2. Sistema de barreira bioquÃmica como alternativa para o tratamento de percolado
Nos paÃses desenvolvidos da Europa e AmÃrica do Norte, o tratamento in situ de efluente de aterro sanitÃrio surgiu na dÃcada de 50. Desde entÃo, diversos processos de tratamento vÃm sendo aplicados, com destaque para os processos biolÃgicos. Contudo, em muitos paÃses, a eficÃcia do tratamento unicamente biolÃgico nÃo satisfaz a legislaÃÃo ambien

3. Degradation of Pyridine by Micrococcus luteus Isolated from Soil †
An organism capable of growth on pyridine was isolated from soil by enrichment culture techniques and identified as Micrococcus luteus. The organism oxidized pyridine for energy and released N contained in the pyridine ring as ammonium. The organism could not grow on mono- or disubstituted pyridinecarboxylic acids or hydroxy-, chloro-, amino-, or methylpyrid
