In the last decades, photocatalysis has arisen as a solution to degrade emerging pollutants such antibiotics. However, reduced photoactivation of TiO2 under visible radiation constitutes major drawback because 95% sunlight is not being used in this process. Thus, it critical modify nanoparticles improve ability absorb from sunlight. This work reports on synthesis decorated with gold (Au) by deposition-precipitation method for enhanced photocatalytic activity. The produced nanocomposites 40%...
Photocatalysis has become an attractive process to treat wastewater since it allows a rapid and efficient degradation of micropollutants in water. A solution ciprofloxacin (CIP) was photocatalytically treated by ultraviolet light (UVA) titanium dioxide (TiO2) or zinc oxide (ZnO) nanoparticles. Toxicity CIP the solutions, as well toxicity TiO2 ZnO irradiated nanoparticles, evaluated towards Vibrio fischeri. The lowest concentration tested, 10 μg L−1, leads 50% luminescence inhibition....
Sulfamethoxazole (SMX) is an antibiotic commonly used to treat human and animal infections. Therefore, it one of the most identified pharmaceuticals worldwide in surface water wastewater treatment plants. This work exploited Pleurotus ostreatus Lentinus sajor-caju produce laccase by using agricultural food residues as substrates, specifically vine pruning brewer's spent grains. The fungal laccases produced were then tested degradation SMX a water-based environment, both absence presence...
A new laccase was purified from Trametes hirsuta IMA2002. The had a molecular mass of 62 kDa and an isoelectric point pH 7. It optimum 3.0 temperature 55°C. quite stable at 30°C 4.0 with half-life more than 100 hours. On ABTS, syringaldazide, DMP the showed KM Kcat values 75, 12 37 μM 64, 83 54 s−1, respectively. structurally diverse commercial dyes Indigo Carmine, Lanaset Blue 2R, Diamond Black PV 200 Fast Brown were oxidized by laccase. While rate extent decolorization latter dye...
The conversion of organic matter to methane through anaerobic digestion (AD) process can be enhanced by different materials. However, literature reports show inconsistent results on the effect materials in AD systems. In this study, we evaluated influence inoculum's activity production (MP) efficiency presence (activated carbon (AC), magnetite (Mag), and zeolite (Zeo)). inocula included pure cultures methanogens, syntrophic cocultures, complex microbial communities, kinetic parameters...
A fibrilação atrial (FA) é uma arritmia caracterizada pela desorganização da atividade elétrica do átrio, dificultando o diagnóstico, especialmente em pacientes assintomáticos. FA pode levar à formação de coágulos no coração, aumentando risco derrames (AVCs), sendo perigosa para com fatores como hipertensão e diabetes. O tratamento envolve mudanças estilo vida, prevenção tromboses controle frequência cardíaca. Novos anticoagulantes orais (DOACS) têm sido usados prevenir eventos...
Environmental pollution has become one of society’s main concerns, which is why it increasingly necessary to look for new effective remediation strategies. The applicability artificial intelligence (AI) tools in different areas knowledge attracted the attention academic community due their ability process large datasets efficiently and deliver rapid, reliable predictions. Among them, neural networks (ANNs) have stood out as some aids environmental control research. In this review, we...
O Acidente Vascular Encefálico (AVE) é um evento clínico caracterizado por disfunção de perfusão sanguínea da circulação encefálica. Tal acontecimento possui diversas etiologias, desde a obstrução placas ateroscleróticas até causas infecciosas. Entre as infecciosas, endocardite configura-se como agente destaque, sendo fator risco para ocorrências neurológicas. Essa revisão apresenta o objetivo avaliar relação entre os portadores infecciosa com episódios acidente vascular encefálico, modo...
Alternative inexpensive complex nitrogen- and phosphate sources from agriculture, green grass juice (GGJ) silage (SJ), were added to cultivation medium in order investigate their impact on growth of the well-known polyhydroxyalkanoate (PHA) accumulating strain Wautersia eutropha. The influence these additives was directly compared with cultivations defined minimal mineral (M) as well same supplemented more expensive additives: corn steep liquor (CSL) casamino acids (CA). It turned out that...
Abstract Laccases are useful biocatalysts for many diverse biotechnological applications. In this study we have established efficient and reliable expression systems high‐throughput screenings the recombinant CotA‐laccase from Bacillus subtilis . The levels of cotA‐laccase were compared in five different Escherichia coli host strains growing 96‐well microtiter plates under culture conditions. Lower coefficients variance (around 15%) achieved using crude cell lysates BL21 KRX microaerobic...
Emerging pollutants are an essential class of recalcitrant contaminants that not eliminated from water after conventional treatment. Here, a photocatalytic microporous membrane based on polyvinylidene difluoride-co-trifluoroethylene (PVDF−TrFE) with immobilised TiO2 nanoparticles, prepared by solvent casting, was tested against representative emerging pollutants. The structure and composition these polymeric membranes were characterized scanning electron microscopy, energy dispersive X-ray...
Effluents from the textile industry are an active problem in sector and one of world’s main environmental problems. The conventional treatments applied not always efficient terms compliance with legislation, and, many cases, efficiency treatment is guaranteed by enormous energy expenditure involved, camouflaging momentary effectively treating it. In this work, batch reactors immobilized biomass Aspergillus niger AN400 were arranged series for real wastewater containing approximately 20 mg/L...
