Synthetic biology to engineer bacteriophage genomes
Costa, Ana Rita; Milho, Catarina; Azeredo, Joana; Pires, Diana Priscila PensoRecent advances in the synthetic biology field have enabled the development of new molecular biology techniques used to build specialized bacteriophages with new functionalities. Bacteriophages have been engineered towards a wide range of applications including pathogen control and detection, targeted drug delivery, or even assembly of new materials. In this chapter, two strategies that have been successfully u...
Anti-aflatoxigenic effect of organic acids produced by Lactobacillus plantarum
Guimarães, Ana Cristina Silva Esperança; Santiago, A.; Teixeira, J. A.; Venâncio, Armando; Abrunhosa, LuísLactic acid bacteria (LAB), which are commonly used in the production of fermented foods, have been gaining attention for their antifungal and antimycotoxin properties. In this work, the strain Lactobacillus plantarum UM55 was selected among other LAB for inhibiting the growth of Aspergillus flavus. Further, it is shown that cell-free supernatant (CFS) of this strain inhibits the production of aflatoxins (AFLs)...
In vitro activity of bacteriophages against planktonic and biofilm populations ...
Pires, Diana Priscila Penso; Melo, Luís D. R.The in vitro activity of bacteriophages against planktonic cultures and biofilms is commonly evaluated by culture methods. However, these methods can lead to an underestimation of total bacterial cells when they undergo different physiological states. This chapter describes the methodology used to assess the in vitro activity of bacteriophages against planktonic cultures of bacteria in different metabolic state...
Chestnut honey and bacteriophage application to control Pseudomonas aeruginosa ...
Oliveira, A.; Sousa, Jéssica; Silva, A.; Melo, Luís D. R.; Sillankorva, SannaChronic skin wounds represent a major burn both economically and socially. Pseudomonas aeruginosa and Escherichia coli are among the most common colonizers of infected wounds and are prolific biofilm formers. Biofilms are a major problem in infections due to their increasingly difficult control and eradication, and tolerance to multiple prescribed drugs. As so, alternative methods are necessary. Bacteriophages ...
Candida glabrata biofilms: mechanisms of antifungal resistance and matrix role
Rodrigues, Célia FortunaDoctoral dissertation for PhD degree in Chemical and Biological Engineering; Candidiasis are the most common fungal diseases, especially among immunosuppressed, hospitalized and patients with prolonged contact to medical devices. Generally, Candida albicans is the most encountered Candida spp., however, in the last decades, non-Candida albicans Candida (NCAC) spp. have been increasing their responsibility in th...
Thermodynamic, rheological and structural properties of edible oils structured ...
Fasolin, Luiz H.; Cerqueira, Miguel Ângelo Parente Ribeiro; Pastrana, L. M.; Vicente, A. A.; Cunha, R. L.Supplementary data associated with this article can be found, in the online version, at https://doi.org/10.1016/j.foostr.2018.03.003.; The effect of different oil phases and low molecular weight organogelators (LMOGs) structures on edible oils was investigated through differential scanning calorimetry (DSC), rheology and small-angle X-ray scattering (SAXS). Different gelators (glyceryl tristearateGT; sorbitan t...
Physiological protection of probiotic microcapsules by coatings
Ramos, Philippe E.; Cerqueira, Miguel Ângelo Parente Ribeiro; Teixeira, J. A.; Vicente, A. A.Nowadays, food and nutrition have a greater impact in people's concerns, with the awareness that nutrition have a direct impact in health and wellbeing. Probiotics have an important role in this topic and consumers are starting to really understand their potential in health, leading to an increasing interest of the companies to their commercial use in foods. However, there are several limitations to the use of ...
Gamma irradiation effects on ochratoxin A: degradation, cytotoxicity and applic...
Calado, Thalita; Fernández-Cruz, María Luisa; Verde, Sandra Cabo; Venâncio, Armando; Abrunhosa, LuísOchratoxin A (OTA) is one of the main mycotoxins that can be found in food. The use of gamma radiation is a technique for preserving food that may exert some effects on mycotoxins. OTA was irradiated in its dry form, in aqueous and in methanolic solutions, and in wheat flour, grape juice and wine. Additionally, the toxicity of OTA irradiated in water was tested. In aqueous solutions, more than 90% of the OTA wa...
Colorectal cancer cells increase the production of short chain fatty acids by P...
Casanova, Marta Alexandra Rodrigues; Azevedo-Silva, João; Rodrigues, L. R.; Preto, AnaPropionibacterium freudenreichii is a commercially relevant bacterium with probiotic potential. This bacterium can exert protective effects particularly against colorectal cancer (CRC), via the production of short chain fatty acids (SCFA), namely acetate and propionate. In this work, we aimed to evaluate the performance and adaptation capacity of P. freudenreichii to a simulated digestive stress using different...
Insight into the role of facultative bacteria stimulated by micro-aeration in c...
Duarte, Maria Salomé; Silva, Sérgio A.; Salvador, Andreia F.; Cavaleiro, A. J.; Stams, Alfons Johannes Maria; Alves, M. M.; Pereira, M. A.Conversion of unsaturated long chain fatty acids (LCFA) to methane in continuous bioreactors is not fully understood. Palmitate (C16:0) often accumulates during oleate (C18:1) biodegradation in methanogenic bioreactors, and the reason why this happens and which microorganisms catalyze this reaction remains unknown. Facultative anaerobic bacteria are frequently found in continuous reactors operated at high LCFA ...
