Reserve mobilization and secondary metabolites during seed germination and seedling establishment of the tree Erythrina velutina (Fabaceae)

Rev. biol. trop; 71 (1), 2023
Introduction: The lack of knowledge on seed germination and seedling establishment is a main constraint for the restoration of degraded areas, including the tropical dry forest known as Caatinga. Objective: To assess reserve and secondary metabolite mobilization during seed germination and seedling estab...

Photocatalytic Degradation of Textile dye Orange-122 Via Electrospray Mass Spectrometry

Abstract This work reports the study of the potential application of Zn/TiO2 catalysts, obtained by the sol-gel method, in processes of environmental decontamination through the reactions of photodegradation of textile dye, followed by electrospray mass spectrometry. The catalysts synthesis was performed...

Monitorización de la capacidad de degradación de las nuevas bacterias haloalcalifílicas resistentes a cloruro de tributiltina (TBTCl) en una ubicación contaminada por butiltina
Monitoring the degradation capability of novel haloalkaliphilic tributyltin chloride (TBTCl) resistant bacteria from butyltin-polluted site

Rev. argent. microbiol; 51 (1), 2019
Tributyltin (TBT) is recognized as a major environmental problem at a global scale. Haloalkaliphilic tributyltin (TBT)-degrading bacteria may be a key factor in the remediation of TBT polluted sites. In this work, three haloalkaliphilic bacteria strains were isolated from a TBT-contaminated site in the M...

Gestão sustentável para área contaminada em campus universitário

A presença de contaminação por substâncias perigosas no solo e na água subterrânea acarreta inúmeros problemas, tais como: risco à saúde humana e aos ecossistemas; comprometimento da água para abastecimento público; e redução do valor econômico e da função social do terreno. Embora as tec...

Microbial-induced remediation of Zn2+ pollution based on the capture and utilization of carbon dioxide

Electron. j. biotechnol; 19 (1), 2016
Background: Microbial-induced remediation of Zn2+ pollution based on the capture and utilization of carbon dioxide was investigated. In this study, carbon dioxide was absorbed and transformed into carbonate ions under the enzymatic action of Paenibacillus mucilaginosus, which was being utilized to minera...

Seleção de ideótipos de espécies florestais de múltiplo uso em planícies fluviais do Baixo Amazonas, Pará

Acta amaz; 40 (1), 2010
A pesquisa objetivou selecionar ideótipos arbóreos de múltiplo uso, baseado em informações etnobotânicas de comunidades ribeirinhas de planícies fluviais do Baixo Amazonas, Pará, para uso em sistemas silvipastoris. Como essas áreas foram antropizadas pela agricultura seguida da pecuária, esses ...

Sobrevivência de espécies arbóreas plantadas em clareiras causadas pela colheita de madeira em uma floresta de terra firme no município de Paragominas na Amazônia brasileira

Acta amaz; 40 (1), 2010
Analisou-se a sobrevivência de mudas plantadas em 400 clareiras causadas por exploração florestal de impacto reduzido, em floresta de terra firme na Amazônia Oriental. Foram plantadas 3.818 mudas de 17 espécies, das quais apenas Schizolobium amazonicum não ocorre na área de estudo. A distância en...

Evaluating the potential of natural reproduction and artificial techniques to increase Acropora cervicornis populations at Discovery Bay, Jamaica

Rev. biol. trop; 54 (supl.3), 2006
Shallow water Acropora species have become uncommon on north coast Jamaican coral reefs owing to a number of factors. On many reefs, algae have taken their place. The result is loss of habitat for many species of fish and invertebrates and less attractive reefs with fewer fish. These reefs appear to be p...
