Alleviation of Fe-induced chlorosis of soybean plants grown in calcareous soil ...
Arcas, Alejandra; Sadeghi, S. Maryam; Lucena, Juan J.; Vindeirinho, João M.; Soares, Eduardo V.; Soares, Helena M. V. M.; López-Rayo, SandraThe concerns about the unsustainability of traditional synthetic Fe chelates lead to the search for new environmentally friendly alternatives, such as siderophores-based fertilizers. In this work, the focus was on the evaluation of a bio-based Fe-chelate fertilizer obtained from the culture of the siderophore-producer bacterium Rhizobium radiobacter. The suitability of a freeze-dried fertilizer formulated from ...

Soares, Eduardo V.; Petropoulos, Spyridon A.; Soares, Helena M. V. M.[editorial excerpt] The modern cropping industry has to address food security challenges related to the increasing world population, the pressure of climate change on crop production, and the adverse effects of anthropogenic activities on agro-ecosystems (Boix-Fayos and de Vente, 2023; Grigorieva et al., 2023). Therefore, various strategies have been suggested (e.g. Green Deal, Soil Deal, Farm to Fork, and Euro...

Editorial: Bio-based solutions for sustainable development of agriculture
Soares, Eduardo V.; Petropoulos, Spyridon A.; Soares, Helena M. V. M.In summary, this Research Topic comprises a collection of 16 articles that offer new and updated knowledge about biofertilizers, biocontrol and improved resilience to environmental stressors. The information presented can be useful in the future development of bio-based products that are expected to be used, as an alternative to current agrochemicals, in modern and more sustainable agriculture.
Harmful effects of metal(loid) oxide nanoparticles
Soares, Eduardo V.; Soares, Helena M. V. M.The incorporation of nanomaterials (NMs), including metal(loid) oxide (MOx) nanoparticles (NPs), in the most diversified consumer products, has grown enormously in recent decades. Consequently, the contact between humans and these materials increased, as well as their presence in the environment. This fact has raised concerns and uncertainties about the possible risks of NMs to human health and the adverse effe...
Modulation of siderophore production by Pseudomonas fluorescens through the man...
Vindeirinho, João M.; Soares, Helena M. V. M.; Soares, Eduardo V.Pseudomonas fluorescens has the ability to produce the siderophore pyoverdine, a biotechnologically significant iron chelator, which has a wide range of potential applications, such as in agriculture (iron fertilizers) and medicine (development of antibiotics). The present work aimed to evaluate the influence of culture medium composition on the production of siderophores by P. fluorescens DSM 50090, an industr...
A simple, efficient and selective process for recycling La (and Al) from fluid ...
Sadeghi, S. Maryam; Jesus, João; Pinto, Edgar; Almeida, Agostinho A.; Soares, Helena M. V. M.Spent fluid cracking catalyst (FCC) is an abundant waste material derived from oil refining processes and notably characterized by its content in rare earth metals, such as cerium (Ce) and lanthanum (La). In this work, it was our main aim to develop a simple but effective flowsheet, based on a single acid assisted leaching step followed by two consecutive precipitation steps, for recovering La with high purity ...
Nickel Oxide Nanoparticles Trigger Caspase- and Mitochondria-Dependent Apoptosi...
Sousa, Cátia A.; Soares, Helena M. V. M.; Soares, Eduardo V.The expansion of the industrial use of nickel oxide (NiO) nanoparticles (NPs) raises concerns about their potential adverse effects. Our work aimed to investigate the mechanisms of toxicity induced by NiO NPs, using the yeast Saccharomyces cerevisiae as a cell model. Yeast cells exposed to NiO NPs exhibited typical hallmarks of regulated cell death (RCD) by apoptosis [loss of cell proliferation capacity (cell v...
Metal(loid) oxide (Al2O3, Mn3O4, SiO2 and SnO2) nanoparticles cause cytotoxicit...
Sousa, Cátia A.; Soares, Helena M. V. M.; Soares, EduardoIn this work, the physicochemical characterization of five (Al2O3, In2O3, Mn3O4, SiO2 and SnO2) nanoparticles (NPs) was carried out. In addition, the evaluation of the possible toxic impacts of these NPs and the respective modes of action were performed using the yeast Saccharomyces cerevisiae. In general, in aqueous suspension, metal(loid) oxide (MOx) NPs displayed an overall negative charge and agglomerated; ...
