Chemical Characterization and Biological Properties Assessment of Euphorbia res...
Boutoub, Oumaima; El-Guendouz, Soukaïna; Matos, Isabel; El Ghadraoui, Lahsen; Costa, Maria Clara; Carlier, Jorge D.; 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...
Electrical impedance spectroscopy for potassium content analysis and botanical ...
Elamine, Youssef; Inácio, Pedro M.C.; Miguel, Maria da Graça; Carlier, Jorge D.; 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 ...
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...

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...
Biodegradation of 17α-Ethinylestradiol by strains of Aeromonas Genus isolated f...
Da Luz Palma, Tânia Cristina; Costa, Maria Clara17α-ethinylestradiol (EE2), a synthetically derived analogue of endogenous estrogen, is widely employed as a hormonal contraceptive and is recognized as a highly hazardous emerging pollutant, causing acute and chronic toxic effects on both aquatic and terrestrial organisms. It has been included in the initial Water Watch List. The aim of this study was to isolate bacteria from consortia recovered from mine sedi...
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 ...

Potential use of agricultural waste—Carob Kibbles (Ceratonia siliqua L.) as a b...
Díaz, Luz Adriana; Dias Carlier, Jorge; Michalak, Izabela; Costa, Maria ClaraThe release of boron (B) into the environment as a result of anthropogenic activity modifies sustainable natural conditions, thus affecting ecosystems. To meet water quality regulations, commercial and natural boron adsorbents are available to reduce its concentrations in industrial effluents, with the former being not only more expensive but also less sustainable. In the publication, the biosorption parameters...
Impact of lead (Pb2+) on the growth and biological activity of Serratia marcesc...
dos Reis Ferreira, Gustavo Magno; Pires, Josiane Ferreira; Ribeiro, Luciana Silva; Dias Carlier, Jorge; Costa, Maria Clara; Schwan, Rosane FreitasMicroorganisms isolated from contaminated areas play an important role in bioremediation processes. They promote heavy metal removal from the environment by adsorbing ions onto the cell wall surface, accumulating them inside the cells, or reducing, complexing, or precipitating these substances in the environment. Microorganism-based bioremediation processes can be highly efcient, low-cost and have low environme...
