Oleate degradation in a continuous microaerophilic bioreactor by a syntrophic co-culture together with facultative anaerobic bacteria
Autor: Duarte, Maria Salomé Lira, Salvador, Andreia Filipa Ferreira, Cavaleiro, Ana Júlia Viana, Stams, Alfons Johannes Maria, Pereira, M. A., Alves, M. M.
Introduction: In high-rate bioreactors, to degrade long-chain fatty acids (LCFA), syntrophic bacteria convert LCFA to acetate and hydrogen/formate, and hydrogenotrophic methanogens keep the H2/formate at low levels, which is essential to allow the co

Facultative anaerobic bacteria: key players in syntrophic fatty acids degradation under microaerophilic conditions
Autor: Magalhães, Carla Isabel Pereira, Duarte, Maria Salomé Lira, Pereira, M. A., Stams, Alfons Johannes Maria, Cavaleiro, Ana Júlia Viana, Alves, M. M.
Anaerobic digestion (AD) is a mature technology that contributes to the sustainable development through the production of energy and products, using microbes as key players. Oxygen, formerly thought as the nemesis of AD, has been shown to benefit the

As comunidades microbianas anaeróbias são constituídas por microrganismos pertencentes aos domínios Bactéria e Arquea, que vivem em ambientes onde o oxigénio molecular está ausente. Estas comunidades desempenham um papel fundamental na decompo

Microaeration in anaerobic digestion systems: effect of low oxygen concentrations on methanogenic communities
Autor: Morais, Bruno, Martins, Valdo Ricardo Alves, Martins, Gilberto, Alves, M. M., Pereira, M. A., Cavaleiro, Ana Júlia Viana
In anaerobic digestion (AD) systems, the coordinated activity of different microbial groups leads to the conversion of complex organic matter into methane. The presence of oxygen may cause negative effects on these processes, by inhibiting the growth

Enhanced oil spill bioremediation with Corksorb
Autor: Martins, Valdo Ricardo Alves, Freitas, Carlos J. B., Carvalho, Ana Rita Castro, Alves, M. M., Pereira, M. A., Cavaleiro, Ana Júlia Viana
Regranulated cork particles are by-products of cork stopper production, which present very high hydrophobicity and oil sorption capacity after thermal treatment [1]. These thermally treated granules have been used as absorbents in the remediation of

Ciprofloxacin removal catalysed by conductive carbon materials
Autor: Silva, Ana R., Antunes, Ana C., Cavaleiro, Ana Júlia Viana, Soares, O. S. G. P, Pereira, M. Fernando R., Alves, M. M., Pereira, Luciana
Current wastewater treatment technologies are not effective in the removal of pharmaceuticals. In anaerobic bioreactors, the electrons produced during the oxidation of organic matter can potentially be used for the biological reduction of pharmaceuti

Palmitate accumulation in continuous bioreactors fed with oleate appears to be the cause for frequent reports of process failure during the anaerobic treatment of lipids or LCFA-rich wastewaters. In these reactors, oleate can be converted to palmitat
