Abstract Zinc oxide nanoparticles (ZnO NPs) are one of the most widely used nanoparticulate materials due to their antimicrobial properties, but main mechanism action (MOA) has not been fully elucidated. This study characterized ZnO NPs by using X-ray diffraction, FT-IR spectroscopy and scanning electron microscopy. Antimicrobial activity against clinically relevant bacteria Escherichia coli , Staphylococcus aureus Pseudomonas aeruginosa Gram-positive model Bacillus subtilis was evaluated...
Tebuthiuron is often used to control weed growth in sugarcane cultures. This herbicide highly toxic and can persist soil for up 2 years according its degradation half-life. Hence, residual effect hazardous the environment local habitants via leaching, surface runoff. Screening out of species green manure as potential phytoremediators tebuthiuron soil, with no vinasse, accordingly scientific point this study. Green selected trial greenhouse were jack bean [ Canavalia ensiformis (L.) DC.],...
Aqueous film-forming foams (AFFFs) are important sources of per- and polyfluoroalkyl substances (PFASs) in soil, groundwater, surface water. Soil microorganisms can convert polyfluorinated into persistent perfluoroalkyl acids, but the understanding co-contaminant stimulation or inhibition PFASs biotransformation is limited. In this study, we investigate how aerobic was affected by common AFFF co-contaminants, such as gasoline aromatics: benzene, toluene, ethylbenzene, o-xylene (BTEX). We...
The aim of this work was to compare different toxicity levels lubricant oils. tests were performed using the earthworm (Eisenia andrei), arugula seeds (Eruca sativa) and lettuce (Lactuca sativa), with three types contaminants (mineral oil, synthetic oil used oil) for various biodegradation periods in soil. indirectly measured contaminants. samples analyzed at t0, t60, t120 t180 days biodegradation. proved very toxic all even after its high. mineral oils biodegraded efficiently soil although...
Vegetable oils and their derivatives, like biodiesel, are used extensively throughout the world, thus posing an environmental risk when disposed. Toxicity testing using test organisms shows how these residues affect ecosystems. tests earthworms (Eisenia foetida) widespread because they a practical resource for analyzing terrestrial organisms. For phytotoxicological analysis, we seeds of arugula (Eruca sativa) lettuce (Lactuca to analyze germination in contaminated soil samples. The...
The evaluation soil quality after bioremediation processes solely on chemical data does not include the effects of toxic substances in organisms. Thus, ecotoxicological assays with seeds are applied to assess effect organisms according their germination sensitivity. objective this study was evaluate a contaminated diesel, biodiesel and waste lubricat oil bioassays using Cucumis sativus (cucumber), Brassica oleracea (kale) Barbarea verna (cress) as test sample buried allow contact...
The purpose of this work was to evaluate the heterogeneity and diversity algae according an aquatic environment polluted by Remazol Red Brilliant dye. Methodology followed Winogradsky columns technique, which describes a microecosystem in glass container. Two were prepared: one control another with dye simulating contaminated environment. experiment under illumination provide light energy photosynthetic organisms alteration two observed quantified: development color changes. Results...
Microorganisms are the primary responsible for food poisoning and spoilage. The purpose of this study was to evaluate different fruit washing methods with tap water, electrolyzed water rhamnolipids solution produced by Pseudomonas aeruginosa LBI, in order inhibit microbial growth. tested organism Eugenia uniflora. fruits were washed periodically inoculated into culture media count colonies on surface. It also observed deterioration level after each treatment. results showed that treatment...
Due to large amounts of wastewater generated by textile industry, studies on degradation and subsequent impact these effluents are needed when they released into water bodies. Since reactive dyes present higher treated physical chemical processes, a photoelectrolytic process was used. Ecotoxicological analysis simulated conducted before after treatment. Winogradsky columns were used, simulating microecosystem where algae growth examined. Results indicated that the achieved satisfactory...
