Structural and mechanical properties of organogels: Role of oil and gelator mol...

Cerqueira, Miguel Ângelo Parente Ribeiro; Fasolin, Luiz H.; Picone, Carolina S. F.; Pastrana, Lorenzo M.; Cunha, Rosiane L.; Vicente, A. A.

This work aims at evaluating the influence of oil and gelator structure on organogels' properties through rheological measurements, polarized microscopy and small-angle X-ray scattering (SAXS). Four different food-grade gelators (glyceryl tristearate GT; sorbitan tristearate ST; sorbitan monostearate SM and glyceryl monostearate - GM) were tested in medium-chain triglyceride and high oleic sunflower (MCT and LC...


Candida glabrata biofilms: How far have we come?

Rodrigues, Célia Fortuna; Rodrigues, Maria Elisa Costa; Silva, Sónia Carina; Henriques, Mariana

Infections caused by Candida species have been increasing in the last decades and can result in local or systemic infections, with high morbidity and mortality. After Candida albicans, Candida glabrata is one of the most prevalent pathogenic fungi in humans. In addition to the high antifungal drugs resistance and inability to form hyphae or secret hydrolases, C. glabrata retain many virulence factors that contr...


Candida species biofilms' antifungal resistance

Silva, Sónia Carina; Rodrigues, Célia Fortuna; Araújo, Daniela; Rodrigues, Maria Elisa Costa; Henriques, Mariana

Candida infections (candidiasis) are the most prevalent opportunistic fungal infection on humans and, as such, a major public health problem. In recent decades, candidiasis has been associated to Candida species other than Candida albicans. Moreover, biofilms have been considered the most prevalent growth form of Candida cells and a strong causative agent of the intensification of antifungal resistance. As yet,...


Monitoring biological wastewater treatment processes: Recent advances in spectr...

Mesquita, Daniela P.; Quintelas, Cristina; Amaral, A. Luís; Ferreira, Eugénio C.

Biological processes based on aerobic and anaerobic technologies have been continuously developed to wastewater treatment and are currently routinely employed to reduce the contaminants discharge levels in the environment. However, most methodologies commonly applied for monitoring key parameters are labor intensive, time-consuming and just provide a snapshot of the process. Thus, spectroscopy applications in b...


Development of a novel user-friendly platform to couple light regime characteri...

Fernandes, Bruno D.; Mota, André; Geada, Pedro; Oliveira, João L.; Teixeira, J. A.; Vasconcelos, Vítor; Vicente, A. A.

Depending on the light regime inside the photobioreactor (PBR) and the flow pattern verified, cells experience different histories with respect to the light regimes they are exposed to, wavelengths of light absorbed and period of time spent under each specific condition. The high heterogeneity of the radiation field inside the PBR due to absorption and scattering of radiation by microalgae/cyanobacteria cells -...


Production of added value bacterial lipids through valorisation of hydrocarbon-...

Castro, Rita; Guimarães, Maura; Oliveira, João Vítor; Pereira, M. Alcina

This work demonstrates that cork used as oil-spill sorbents, contaminated with liquid hydrocarbons, herein demonstrated with hexadecane, can be biologically treated by Rhodococcus opacus B4 with concomitant lipids production. R. opacus B4 consumed up to 96% of hexadecane (C16) impregnated in natural and regranulated cork sorbents after 48 h incubation, producing 0.59 ± 0.06 g of triacylglycerol (TAG) g 1 of C16...

Susceptibility testing of Candida albicans and Candida glabrata to Glycyrrhiza ...

Martins, Natália; Costa-Oliveira, Sofia; Melo, Luís D. R.; Ferreira, Isabel C. F. R.; Azeredo, Joana; Henriques, Mariana; Silva, Sónia Carina

Medicinal plants and their botanical formulations have gained a pivotal attention among scientific researchers mainly due to its action as health promoters. Licorice (Glycyrrhiza glabra L.) constitutes a great example, with an increasingly evidenced antimicrobial potential. Opportunistic yeast infections constitute an alarming public health problem, highly exacerbated by the inefficacy of antifungal drugs and t...


Carvacrol is highly disruptive against coagulase-negative staphylococci in in v...

Gaio, Vânia Silva; Lima, Cláudia Sofia Afonso de; Oliveira, Fernando Eduardo Freitas; França, Ângela Maria Oliveira Sousa; Cerca, Nuno

Aim: To evaluate the antimicrobial activity of carvacrol against stationary-phase planktonic and biofilm cells of coagulase-negative staphylococci and comparison to traditional antistaphylococcal antibiotics. MATERIALS & METHODS: The antimicrobial effect of carvacrol and antibiotics against planktonic and biofilm cells were assessed through quantification of the number of culturable and/or viable cells. Confoca...
