In this paper, the effect of light modulation on photocatalytic ceftriaxone (CEF) degradation in aqueous solution was investigated. The experimental set-up consisted a fixed bed reactor with flat plate geometry and visible LEDs for irradiation. Fe-N-codoped TiO2 photocatalyst immobilized polystyrene (PS) by solvent casting method to achieve structured (Fe-N-TiO2/PS), which loaded photoreactor. Raman UV–Vis diffuse reflectance spectroscopy confirmed presence Fe-N-TiO2 PS surface its uniform...
The ability to form biofilms is a common feature of microorganisms, which can colonize variety surfaces, such as host tissues and medical devices, resulting in infections highly resistant conventional drugs. This aspect particularly critical polymicrobial involving both fungi bacteria, therefore, eradicate severe infections, new effective anti-biofilm strategies are needed. efficacy pentadecanal pentadecanoic acid agents has been recently reported against different bacterial strains. Their...
The high virulence of Candida auris, a pathogen fungus considered as global threat for public health, is due to its peculiar traits such intrinsic resistance conventional antifungals. Its biofilm lifestyle certainly promotes the prolonged survival C. auris after disinfection or antifungal treatments. In this work, first time, we detected persister cells in microwell plate model, following caspofungin treatment. Furthermore, showed how persisters can progressively develop new situ, mimicking...
Candida species are the most common fungal pathogens infecting humans and can cause severe illnesses in immunocompromised individuals. The increased resistance of to traditional antifungal drugs represents a great challenge clinical settings. Therefore, novel approaches overcome desired. Here, we investigated use an antimicrobial peptide WMR against albicans non-albicans vitro vivo. Results showed activity on all planktonic cells at concentrations between 25 μM >50 exhibited sub-MIC inhibit...
Biofilms have been found growing on implantable medical devices. This can lead to persistent clinical infections. The highly antibiotic-resistant property of biofilms necessitates the search for both potent antimicrobial agents and novel antibiofilm strategies. Natural product-based anti-biofilm were be as efficient chemically synthesized counterparts with fewer side effects. In present study, effects limonene an agent evaluated Pseudomonas aeruginosa Staphylococcus aureus biofilm formed...
Azo dyes, the most common synthetic dyes used in textile industry, are known xenobiotic compounds and recalcitrant to conventional degradation treatments. As consequence, such contaminants often discharged into effluents, treating aquatic ecosystems. Among several processes, use of zero valent iron (ZVI) represents a suitable alternative degrade organic molecules containing azo bonds. However, its applications limited by corrosion loss reactivity over time. To overcome these constraints, ZVI...
Monolithic composite aerogel based on a photocatalytic system, constituted by Fe0 (ZVI) coupled with ZnS (FZ), embedded into syndiotactic polystyrene (sPS) matrix was used, for the first time, in lindane degradation under UV light. The content of FZ photocatalyst inside monolithic (FZsPS) 3 wt%. FESEM images FZsPS indicate that is well dispersed polymer matrix. EDS analyses and temperature-programmed reduction (TPR-H2) measurements revealed an interpenetrated structure ZVI phases as presence...
Polycyclic aromatic hydrocarbons (PAHs) consist of a group over 100 different organic compounds mainly generated by anthropogenic activities. Because their low water solubility, they tend to be accumulated in sediment, where degradation rate is very low. Few studies have been carried out so far investigate the effects PAHs on Artemia franciscana. easy manage at laboratory scale, but it not sensitive biological model considering traditional endpoints (i.e., mortality). In addition evaluating...
Polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) represent the most common pollutants in marine sediments. Previous investigations demonstrated short-term sublethal effects of sediments polluted with both contaminants on sea urchin Paracentrotus lividus after 2 months exposure mesocosms. In particular, morphological malformations observed P. embryos deriving from adults exposed to PAHs PCBs were explained at molecular levels by de novo transcriptome assembly...
Oxylipins are diatom-derived secondary metabolites, deriving from the oxidation of polyunsatured fatty acids that released cell membranes after damage or senescence these single-celled algae. Previous results revealed harmful toxic effects polyunsaturated aldehydes (PUAs) and hydroxyacids (HEPEs) on sea urchin Paracentrotus lividus embryonic development by testing individual compounds mixtures same chemical group. Here, we investigated combined at morphological molecular level for first...
Pharmaceuticals can be considered a global threat to aquatic ecosystems due their pseudo-persistence and potential toxicity towards non-target species. Amoxicillin (AMX) carbamazepine (CBZ) mixture (1:1) were investigated on the marine copepod Tigriopus fulvus (Fischer, 1860) considering both acute chronic endpoints. While exposure did not directly affect survival, reproductive endpoints affected like mean egg hatching time that was significantly longer than negative control for treatments...
Adult sea urchins and their embryos are ideal targets to investigate the medium- long-term effects of various toxic agents, such as organic inorganic pollutants, forecast mitigate environmental effects. Similarly, small colonial tunicates Botryllid ascidians may reveal acute toxicity processes permit quick responses for management contaminants impacting coastal waters, preserve functional integrity marine ecosystems. This investigation compares two model invertebrates, urchin Paracentrotus...
Nano-zero-valent iron (nZVI) and activated carbon (AC) addition are ongoing techniques for the remediation of hydrophobic organic compound-contaminated sediment water, but with still unexplored eco(toxico)logical implications, especially when applied in situ. In this study, we investigated AC nZVI as methods marine contaminated including chemical toxicity (Artemia franciscana survival genotoxicity) surveys. The removal efficiency (about 99%) was similar both seawater, while nauplii adults...
