1. Purification and caracterization of α-galactosidases from fungus Penicillium griseoroseum to application in hydrolysis of ologosaccharides in soybean products / Purificação e caracterização de α-galactosidases do fungo Penicillium griseoroseum para utilização na hidrólise de oligossacarídeos de rafinose em derivados de soja
The present work aims to evaluate the efficiency of the purified α-galactosidases from Penicillium griseoroseum in the hydrolysis of the RO present in the free fat soy extract. Penicillium griseoroseum was cultivated in a mineral medium which contained galactomanana as a source of carbone, for 120 hours, at 28 oC. After this period, the medium was dialy

2. Influence of the contact bed in the efficiency of removal of iron of underground waters / Influência do leito de contato na eficiência de remoção de ferro de águas subterrâneas
Este trabalho teve como objetivo avaliar a influência da unidade leito de contato na eficiência de remoção ferro em Estação de Tratamento de Água (ETA) tipo desferrização que trata água subterrânea. Os ensaios foram realizados em uma instalação piloto, composta por um aerador tipo tabuleiro, um leito de contato de fluxo ascendente e um filtro r�

3. Integração digital de imagens de radar e LANDSAT-TM com dados geológicos e aerogamaespectrométricos no auxílio ao mapeamento geológico da região do Complexo Granítico Estrela - Pará (PA) / Radar, geologic, airborne gamma ray and LANDSAT-TM digital data integration for geological mapping of the Estrela Granite Complex (PA).
This work is focused on the geotectonic context of the Carajás Mineral Province, Amazon Craton, which represents the most important Brazilian Mineral Province and hosts iron, cooper, gold, manganese and nickel deposits. At the end of Archean age, during the tecno-metamorphic evolution, moderated alkaline granitoids were generated, such as, Estrela Granite C

5. Histochemical study of asbestos fibre coating in experimental carrageenin granulomas
Governa, M., and Rosanda Vadalà, C. (1973).British Journal of Industrial Medicine,30, 248-252. Histochemical study of asbestos fibre coating in experimental carrageenin granulomas. To study the composition of asbestos body coating, asbestos particles present in experimental carrageenin granulomas were tested histochemically for mucopolysaccharides, ferric a

6. Blood ferritin concentrations in newborn infants and the sudden infant death syndrome.
Liver iron concentrations have been shown to be higher in victims of SIDS than in postmortem controls suggesting that high levels of tissue iron may be implicated in SIDS. To determine whether infants who subsequently die from SIDS are born with greater iron stores than those who do not, the iron stores in newborn infants were assessed retrospectively by mea

7. Role of heme compounds and haptoglobin in Vibrio vulnificus pathogenicity.
An induced peritonitis model was employed in mice to determine whether heme-containing molecules enhance the lethality of infections by Vibrio vulnificus. The lethality of intraperitoneal (ip) inocula of the bacteria was increased by concurrent injections (ip) of hemoglobin, methemoglobin, or hematin, but not by myoglobin. Similar results were obtained in mi

8. Molecular Relationship between Two Groups of the Genus Leptospirillum and the Finding that Leptospirillum ferriphilum sp. nov. Dominates South African Commercial Biooxidation Tanks That Operate at 40°C
Iron-oxidizing bacteria belonging to the genus Leptospirillum are of great importance in continuous-flow commercial biooxidation reactors, used for extracting metals from minerals, that operate at 40°C or less. They also form part of the microbial community responsible for the generation of acid mine drainage. More than 16 isolates of leptospirilla were inc
