Batch studies on the biodegradation of paracetamol and 1,4-hydroquinone by nove...
Lara-Moreno, Alba; Fatma El-Sayed; Cox, Cymon; Costa, Maria Clara; Carlier, JorgeThe emerging pollutant paracetamol (APAP) is one of the most prescribed drugs worldwide. In addition, APAP and its main metabolites, namely, 4-aminophenol (4-AP), hydroquinone (H2Q), benzoquinone (BQ), and 2,5-dihydroxy-1,4-benzoquinone (2,5-OH-BQ), among others, are frequently detected in wastewater treatment plants (WWTPs) influents, effluents, and the environment. Thus, continuous release into the environmen...
Electrical impedance spectroscopy for potassium content analysis and botanical ...
Elamine, Youssef; INÁCIO, PEDRO; Miguel, Maria da Graça; Carlier, Jorge; Costa, Maria Clara; Estevinho, Leticia M.; Gomes, Henrique L.Minerals are reported to dominate the electrical properties of honey and indicate its botanical and geographical origins. In this study, Electrochemical Impedance Spectroscopy (EIS) was used to assess the relation between mineral elements, electrical properties and botanical origin using three honey varieties - Citrus sp., Eucalyptus sp., and Erica sp. These varieties are identified through pollen analysis and ...
New bacterial strains for ibuprofen biodegradation: drug removal, transformatio...
Lara-Moreno, Alba; Costa, Maria Clara; Vargas‐Villagomez, Ayleen; Carlier, JorgeIbuprofen (IBU) is a significant contaminant frequently found in wastewater treatment plants due to its widespread use and limited removal during treatment processes. This leads to its discharge into the environment, causing considerable environmental concerns. The use of microorganisms has recently been recognized as a sustainable method for mitigating IBU contamination in wastewater. In this study, new bacter...
Acid mine drainage bioremediation using bacteria enriched from the confluence z...
Nobahar, Amir; Fitas, Eduardo Trindadde; Costa, Maria Clara; Carlier, JorgeSediments from the confuence zone between an acid mine drainage stream and a water stream receiving the efuent from a municipal wastewater treatment plant were inoculated in a Postgate B medium base having methanol, glycerol, or etha[1]nol as carbon source/electron donor, over a pH range between 2.00 and 6.00, aiming to obtain native cultures enriched in acidophilic/acid-tolerant sulfate-reducing bacteria. The ...
Chemical characterization and biological properties assessment of Euphorbia res...
Boutoub, Oumaima; El-Guendouz, Soukaina; Matos, Isabel; El Ghadraoui, Lahsen; Costa, Maria Clara; Carlier, Jorge; Faleiro, Maria LeonorAlthough the plants of the genus Euphorbia are largely exploited by therapists in Morocco, the composition and antibacterial activities of propolis from these plants are still unknown. To address this gap, this study aimed to characterize the pollen type, the volatile compounds, and the phenolic and mineral profiles of three Euphorbia propolis samples collected in Morocco and evaluate their antimicrobial activi...
Bacterial bioaugmentation for paracetamol removal from water and sewage sludge....
Lara-Moreno, A.; Vargas-Ordóñez, A.; Villaverde, J.; Madrid, F.; Carlier, Jorge; Santos, J. L.; Alonso, E.; Morillo, E.Wastewater treatment plants (WWTPs) are recognized as significant contributors of paracetamol (APAP) into the environment due to their limited ability to degrade it. This study used a bioaugmentation strategy with Pseudomonas extremaustralis CSW01 and Stutzerimonas stutzeri CSW02 to achieve APAP biodegradation in solution in wide ranges of temperature (10-40 °C) and pH (5-9), reaching DT values < 1.5 h to degra...
Recovery of catalytic metals from leaching solutions of spent automotive cataly...
Nobahar, Amir; Carlier, Jorge; Costa, Maria ClaraThis study investigates the potential of hydroalcoholic extracts of Cistus ladanifer L., Erica Andevalensis and Rubus idaeus L. as a green method for the recovery of platinum group metals (PGMs) from both synthetic unimetallic solutions and multimetallic solutions obtained from the leaching of two different spent automotive catalytic converters (SACC). Experiments with unimetallic solutions revealed that E. and...
A new application of solvent extraction to separate copper from extreme acid mi...
Nobahar, Amir; Melka, Alemu Bejiga; Pusta, Alexandra; Lourenço, João P.; Carlier, Jorge; Costa, Maria ClaraOver the last decade, AMD waters have gained more attention as a potential source of metals due to the emerging need to recover or recycle metals from secondary resources. Metals recovery supports sustainability and the development of a circular economy with benefits for resource conservation and the environment. In this study, five extractants (Acorga M5640, LIX 54, LIX 622, LIX 622 N, and LIX 864) diluted (15...
Antioxidant activity and enzyme inhibitory potential of Euphorbia resinifera an...
Boutoub, Oumaima; EL-Geundouz, Soukaina; Estevinho, Leticia M.; Paula, Vanessa B.; Aazza, Smail; El Ghadraoui, Lahsen; Rodrigues, Brígida; Raposo, SaraNatural products may be applied in a wide range of domains, from agriculture to food and pharmaceutical industries. In this study, the antioxidant properties and the capacity to inhibit some enzymatic activities ofEuphorbia resiniferaandEuphorbia officinarumaqueous extracts and honeys were assessed. The physicochemical characteristics were also evaluated. Higher amounts of iron, copper and aluminium were detect...
An autochthonous aerobic bacterial community and its cultivable isolates capabl...
Palma, Tânia Cristina da Luz; Shylova, Anastasiia; Carlier, Jorge; Costa, Maria ClaraBACKGROUND Fluoxetine is an antidepressant and recalcitrant fluorine pharmaceutical that is poorly biodegraded, so it enters the hydric resources and causes hazardous effects to aquatic environments. According to these fluoxetine features, the main aim of the present research was to find resistant bacteria in environmental samples with a high degradation efficiency. RESULTS The results obtained from raw municip...
