Chromera velia is a newly cultured photosynthetic marine alveolate. This microalga has a high iron requirement for respiration and photosynthesis, although its natural environment contains less than 1 nm of this metal. We found that this organism uses a novel mechanism of iron uptake, differing from the classic reductive and siderophore-mediated iron uptake systems characterized in the model ye...

Advanced oxidation processes (AOPs) have become a favored approach in wastewater treatment due to the high efficiency and diverse catalyzed ways. Iron-based materials were commonly used catalyst their environmental friendliness sustainability environment. We collected published papers relative application of modified iron-based AOPs between 1999 2020 comprehensively understand related mechanism...

Cold plasma and ozone sanitation of irrigation solutions can oxidize both microbes non-target micronutrients because their high oxidation-reduction potential (ORP) is a non-selective mode action. The objective this study was to evaluate the effects cold treatment on oxidation iron manganese in nutrient containing one four chelates (iron-ethylenediaminetetraacetic acid (Fe-EDTA), iron-diethylene...

Iron and copper are essential for plants and are important for the function of a number of protein complexes involved in photosynthesis and respiration. As the molecular mechanisms that control uptake, trafficking and storage of these nutrients emerge, the importance of metalloreductase-catalyzed reactions in iron and copper metabolism has become clear. This review focuses on the ferric reducta...

AIMS To determine whether chelated sources of ferric iron were efficient inhibitors of biofilm formation in Pseudomonas aeruginosa and might be suitable for drug delivery to the lungs of cystic fibrosis (CF) patients via nebulization. METHODS AND RESULTS The response of P. aeruginosa biofilms to elevated iron concentrations in the form of eight structurally varied iron chelators in a microtit...

Poorly vascularized areas of solid tumors contain quiescent cell populations that are resistant to cell cycle-active cancer drugs. The compound VLX600 was recently identified to target quiescent tumor cells and to inhibit mitochondrial respiration. We here performed gene expression analysis in order to characterize the cellular response to VLX600. The compound-specific signature of VLX600 revea...

Siderophores are low molecular weight compounds, synthesized and secreted by microorganisms, that specifically bind ferric iron with exceptionally high affinity. Microbes capture these compounds and take up the bound iron through specific, high-affinity systems. Saccharomyces cerevisiae can take up iron bound to siderophores through the transporters of the ARN family; however, the mechanism by ...
