1. PYROLIGNEOUS LIQUOR PRODUCED FROM ACACIA MEARNSII DE WILD WOOD UNDER CONTROLLED CONDITIONS AS A RENEWABLE SOURCE OF CHEMICALS
Acacia mearnsii de Wild (black wattle) is one of the most important trees planted in Southern Brazil for tannin extraction and charcoal production. The pyrolysis of the black wattle wood used for obtaining charcoal is performed in brick ovens, with the gas fraction being sent directly into the environment. The present study examines the condensable compounds

2. PALEOFAUNA E PALEOAMBIENTES DO PLEISTOCENO SUPERIOR NO MUNICÍPIO DE JAGUARARI, NORTE DA BAHIA. / PALEOFAUNA AND PALEOENVIRONMENTS OF THE CITY OF UPPER PLEISTOCENE JAGUARARI, NORTH OF BAHIA.
Estudos de reconstrução paleoambiental (vegetação e clima) são mais abundantes nas regiões Sul, Sudeste e Central do Brasil utilizando pólen depositado em sedimentos lacustres e turfeiras. Por outro lado, na região Nordeste, trabalhos análogos são mais escassos. A partir deste tipo de estudo é possível inferir sobre os processos ecológicos assoc

3. A estrutura e composição de comunidades microbianas (Bacteria e Archaea) em fragmentos de carvão pirogênico de Terra Preta de Índio da Amazônia Central / Structure and composition of bacterial communities (Bacteria and Archaea) in fragments of pyrogenic charcoal from Amazonian Dark Earth in the Central Amazon
Amazonian Dark Earth (ADE), also known as Terra Preta de Índio, present tropical A horizon, high pH, important nutrients for plant growth, high pyrogenic charcoal levels and intense biological activity when compared to its soil of origin. Soil microbial community is essential for ecosystem function, which is involved in fundamental processes such as the dec

4. Biodegradation of linear alkylbenzene sulfonate in anaerobic sequencing biofilm batch reactor with biomass immobilization in charcoal / Degradação de alquilbenzeno linear sulfonado em reator anaeróbio operado em bateladas seqüenciais com biomassa imobilizada em carvão vegetal
This work used an anaerobic sequencing biofilm batch reactor aiming the removal and degradation of the linear alkylbenzene sulfonate (LAS). Biomass from an UASB reactor treating suine wastewater was immobilized in charcoal fragments. The reactor was fed with synthetic substrate with addition of LAS. Feeding happened in four stages: (1) synthetic substrate wi
