Relatório Final do projeto ALOP (ALT20-03-0145-FEDER-000004)
Salgado, Rui; Palma, Patrícia; Morais, M. Manuela; Almeida, Adelaide; Alvarenga, Paula; Antunes, Célia; Aranha, Sergio; Bárias, Samuel; Barrenho, JoelO Projeto ALOP teve início formal a 25 de Maio de 2016 e terminou a 31 de dezembro de 2019. Neste relatório final procuramos dar conta das atividades efetuadas e principalmente dos resultados obtidos. A tarefa está facilitada pois o projeto, em conjunto com as sinergias geradas com outros projetos e as colaborações nacionais e internacionais dos vários membros da equipa permitiram a publicação de um invejável n...
Insight into the efficiency of microalgae’ lipidic extracts as photosensitizers...
Mendonça, Inês; Silva, Daniela; Conde, Tiago; Maurício, Tatiana; Cardoso, Helena; Pereira, Hugo; Bartolomeu, Maria; Vieira, Cátia; Domingues, M. RosárioAntibacterial resistance causes around 1.27 million deaths annually around the globe and has been recognized as a top 3 priority health threat. Antimicrobial photodynamic therapy (aPDT) is considered a promising alternative to conventional antibiotic treatments. Algal lipid extracts have shown antibacterial effects when used as photosensitizers (PSs) in aPDT. In this work we assessed the photodynamic efficiency...
Wastewater disinfection with photodynamic treatment and evaluation of its ecoto...
Bartolomeu, Maria; Gomes, Thierry J.; Campos, Fábio; Vieira, Cátia; Loureiro, Susana; Neves, M. Graça P. M. S.; Faustino, M. Amparo F.Research has demonstrated the presence of viruses in wastewater (WW), which can remain viable for a long period, posing potential health risks. Conventional WW treatment methods involving UV light, chlorine and ozone efficiently reduce microbial concentrations, however, they produce hazardous byproducts and microbial resistance that are detrimental to human health and the ecosystem. Hence, there is a need for n...

Reuse of treated slaughterhouse wastewater from immediate one-step lime precipi...
Madeira, Luís; Teixeira , Margarida Ribau; Nunes, Sérgio; Almeida, Adelaide; Carvalho, FátimaThe transition from the linear economy paradigm to the circular economy in industrial wastewater treatment is on the global agenda. The search for new simple, eco-innovative and low-cost processes for treating industrial wastewater, which can also be used by small- and medium-sized industries, has been a constant challenge to ensure environmental sustainability in all types of industries. The present work aimed...

Simão Madeira, Luís Miguel; Carvalho, Fátima; Almeida, Adelaide; Ribau Teixeira, MargaridaThe transition from the linear economy paradigm to the circular economy in industrial wastewater treatment systems is on the global agenda. The search for new simple, eco-innovative, and low-cost processes for treating industrial wastewater, which can also be used by small and medium-sized industries, has been a constant challenge especially when environmental sustainability is considered. So, a new integrated ...
Optimization of atmospheric carbonation in the integrated treatment immediate o...
Madeira, Luís Miguel; Carvalho, Fátima; Almeida, Adelaide; Ribau Teixeira, MargaridaLong carbonation time has been a common feature in the integrated process composed by immediate one-step lime precipitation and atmospheric carbonation. This work aims to understand how carbonation time can be influenced by reaction pH, as well as how reactor area/volume ratio affects carbonation time and ammonia removal, using slaughterhouse wastewater due to its variable characteristics. In the integrated imm...
Tunning processes for organic matter removal from slaughterhouse wastewater tre...
Simão Madeira, Luís Miguel; Almeida, Adelaide; Rosa Da Costa, Ana; Mestre, Ana S.; Carvalho, Fátima; Ribau Teixeira, MargaridaAdsorption using unmodified/modified commercial activated carbons and constructed wetlands (CW) planted with Vetiveria zizanioides were evaluated as tuning processes for lowering chemical oxygen demand (COD) from slaughterhouse wastewater pretreated by the integrated process of immediate one-step lime precipitation and atmospheric carbonation. Powdered and granular activated carbons (PAC and GAC), and PAC and G...
Effect of β-cyclodextrin on the CO release kinetics and antimicrobial activity ...
Monteiro, Rodrigo P.; Calhau, Isabel B.; Gomes, Ana C.; Pereira, Carla; Vieira, Cátia; Faustino, M. Amparo F.; Almeida, Adelaide; Pillinger, MartynIn the present work the possibility of improving the solubility, bioavailability and bactericidal activity of the carbon monoxide releasing molecule (CORM) [Mo(CO)5Br]− (as its tetraethylammonium salt) (1) by solvent-free co-grinding with β-cyclodextrin (βCD) in a planetary ball mill was investigated. Data obtained by FT-IR spectroscopy, Raman spectroscopy, powder X-ray diffraction and thermogravimetric analysi...
Starch-based films doped with porphyrinoid photosensitizers for active skin wou...
Lopes, Paloma; Joaquinito, A. Sofia M.; Ribeiro, Artur; Moura, Nuno M. M.; Gomes, Ana T. P.; Guerreiro, Susana G.; Faustino, M. Amparo F.Starch is a biodegradable and biocompatible carbohydrate that, when combined with bioactive molecules, can be processed as biomimetic platforms with enhanced performance, allowing its use as active wound dressing materials. Porphyrinoid photosensitizers can tune the physicochemical/functional profile of biomacromolecules, allowing their use in anti-infective strategies. In this work, the feasibility of using th...
