Assessing the herbicidal potential of Rhodopirellula rubra LF2 extracts: a prom...
Silva, Miguel; Godinho, Ofélia; Lage, Olga; Melo, PaulaBackground: The increasing global population and the corresponding rise in food demand require improvements in crop yields, as well as a reduction in the impact of weeds in agricultural fields. One potential sustainable solution may lie in the ocean—an area of the Earth that remains largely unexplored, yet harbors rich and diverse biodiversity. In our group, marine microorganisms have been found to produce bioa...
From In to Out: assessing antimicrobial-resistant Escherichia coli across treat...
Merêncio, Tiago; Godinho, Ofélia; Lage, Olga; Quinteira, SandraBackground: Wastewater treatment plants (WWTPs) are critical points for the selection and transmission of antimicrobial resistance (AMR), which has become a major global public health concern [1,2]. The One Health approach is essential in addressing this issue, as AMR affects both human and environmental health [3]. Objective: To evaluate the role of WWTPs as reservoirs and/or sources of antimicrobial-resistant...
A comparative analysis of the structural diversity of biosynthetic gene cluster...
Calisto, Rita; Kallscheuer, Nicolai; Lage, OlgaBackground: Planctomycetota are bacteria with a unique cell biology known to possess important potential for the production of new molecules with biological activities. This potential has only recently started to be unveiled, motivated by reported antimicrobial and anticancer activities [1-3]. Three novel secondary metabolites have already been characterized [4,5]. Enzymes involved in the synthesis of bioactive...
Unfit for consumption: microbiological risks of natural water sources in rural ...
Rodrigues, Inês; Godinho, Ofélia; Lage, Olga; Quinteira, SandraBackground: Access to clean and safe water is vital for public health [1], especially in rural areas, where many households depend on untreated natural water sources [2]. Objective: This cross-sectional study combines an epidemiological survey with microbiological analysis to assess the risks of untreated water consumption and identify populations vulnerable to waterborne diseases. Methods: Drinking water sampl...
Exploring the microbiota of Eucalyptus globulus leaves: identification of poten...
Nunes, Telma; Lage, Olga; Quintela, Ana; Melo, PaulaBackground: The most common eucalyptus species in Portugal, Eucalyptus globulus Labill., has been planted as a source of wood for producing high-quality paper pulp since the mid-20th century (ICNF, 2019). Over the past 70 years, the area of eucalyptus plantations has steadily expanded, significantly impacting productivity and leading to an increased reliance on chemical fertilizers to sustain soil fertility acr...
