Investigating bacterial community changes and organic substrate degradation in ...
Barbosa, Sónia G.; Peixoto, L.; ter Heijne, Annemiek; Kuntke, P.; Alves, M. M.; Pereira, M. AlcinaThe present study investigates the changes in the microbial community and the degradation of organic compounds in a microbial fuel cell (MFC) operated on human urine. An anaerobic community was enriched in urine-degrading electroactive microorganisms by stepwise lowering the dilution factor of the anode media from 50 times diluted to undiluted urine. In a duplicated assay a current density of 495±16 mA m-2, a c...
2 - Nanostructured biobased systems for nutrient and bioactive compounds delivery
Cerqueira, Miguel Ângelo Parente Ribeiro; Pinheiro, Ana Cristina; Carmo, Cátia V. S.; Duarte, Catarina M. M.; Cunha, Maria das Graças C.; Vicente, A. A.Nanotechnology is pointed to as one of the hot topics in food science and technology where the use of nanostructured systems for compounds delivery using biobased materials appears as one of the most interesting matters in the field. Due to their advantages when compared with micro- and macroscale systems, nanostructured biobased systems have attracted a great interest from academia and industry where they can ...
Utilização de grânulos de cortiça para estimular a biorremediação aeróbia de hi...
Freitas, Carlos Jorge BatistaDissertação de mestrado integrado em Engenharia Biológica (área de especialização em Tecnologia Ambiental); Os derrames de petróleo constituem um dos desastres ambientais mais graves provocados pelo Homem. Uma das estratégias mais utilizadas para remediação de locais contaminados com petróleo é a contenção e remoção dos hidrocarbonetos por materiais sorventes. Entre estes, a cortiça tem sido aplicada com sucess...
A network perspective on antimicrobial peptide combination therapies: the poten...
Jorge, Paula; Pérez-Pérez, Martín; Rodríguez, Gael Pérez; Pereira, Maria Olívia; Lourenço, AnáliaSupplementary data associated with this article can be found, in the online version, at doi:10.1016/j.ijantimicag.2017.02.012.; Antimicrobial combinations involving antimicrobial peptides (AMPs) attract considerable attention within current antimicrobial and anti-resistance research. The objective of this study was to review the available scientific literature on the effects of antimicrobial combinations involv...
Sodium chloride effect on the aggregation behaviour of rhamnolipids and their a...
Rodrigues, Ana Isabel; Gudiña, Eduardo J.; Teixeira, J. A.; Rodrigues, L. R.In this work, the antifungal activity of rhamnolipids produced by Pseudomonas aeruginosa #112 was evaluated against Aspergillus niger MUM 92.13 and Aspergillus carbonarius MUM 05.18. It was demonstrated that the di-rhamnolipid congeners were responsible for the antifungal activity exhibited by the crude rhamnolipid mixture, whereas mono-rhamnolipids showed a weak inhibitory activity. Furthermore, in the presenc...
A multi-metal risk assessment strategy for natural freshwater ecosystems based ...
Alves, Cristina M.; Ferreira, Carlos M. H.; Soares, Eduardo V.; Soares, Helena M. V. M.Scientifically sound risk assessment strategies and derivations of environmental quality standards for metals present in freshwater environments are currently hampered by insufficient chronic toxicity data collected from natural ecosystems, as well as inadequate information on metal speciation. Thus, the aim of the present study was to evaluate the impact of freshwater containing multiple metals (Cd, Cr, Cu, Ni...
Vineyard pruning waste as an alternative carbon source to produce novel biosurf...
Vecino, Xanel; Rodríguez-López, L.; Gudiña, Eduardo J.; Cruz, J. M.; Moldes, A. B.; Rodrigues, L. R.Abstract Cellulosic sugars extracted from vineyard pruning waste (VPW) were used as a low-cost carbon source for biosurfactant production by Lactobacillus paracasei. The results obtained showed that when glucose from VPW was used, the biosurfactant was a glycolipopeptide, whereas when it was replaced by lactose the biosurfactant produced was a glycoprotein. Additionally, it was found that the extraction process...
Synergistic antimicrobial interaction of honey and bacteriophage in Escherichia...
Ribeiro, Henrique; Oliveira, Ana Cristina Afonso; Silva, Ana Catarina Ramos Lopes; Silva, Maria Daniela; Rodrigues, Célia FortunaI Simpósio de Bioquímica Aplicada; Wound colonization by biofilms-forming bacteria is one of the main obstacles to the treatment of chronic wounds, causing a number of biological and financial problems. Biofilms are structured communities of bacterial cells enclosed in a self-produced polymeric matrix, adhered to inert or living surfaces, blocking antibiotics and patients immune cells from reaching bacteria. Ba...
Targetability of hyaluronic acid nanogel to cancer cells: In vitro and in vivo ...
Pedrosa, Sílvia S.; Pereira, Paula; Correia, A.; Gama, F. M.We have, in previous work developed, characterized and evaluated the biocompatibility of an engineered hyaluronic acid nanogel. Here we assess the targetability of a hyaluronic acid nanogel towards CD44 overexpressing cells, in vitro and in vivo. Results obtained by flow cytometry and confocal fluorescence microscopy shows that nanogel is greatly internalized by non-small cancer lung cells (A549 cells), that ov...
Changing the shape of hair with keratin peptides
Cruz, Célia F.; Sá, M.; Antunes, Egipto; Osorio, H.; Ribeiro, Artur; Cavaco-Paulo, ArturChemical straightening of curly human hair fibres involves the use of strong reducing agents at alkaline pH. Human hair is made of keratin, and the fixation of fibre shape involves the reduction and reformation of new disulphide bonds between keratin molecules. Here, we propose an alternative and green methodology using keratin peptide sequences (10-13 residues) derived from the human genome. In a previous stud...
