Low-cost approaches for the removal of terbuthylazine from agricultural wastewater: Constructed wetlands and biopurification system
(Chemical Engineering Journal, 2018)
Expanding the application scope of on-farm biopurification systems: Effect and removal of oxytetracycline in a biomixture
Antibiotic-containing wastewaters produced in agricultural activities may depress the pesticidedegrading capacity of biomixtures contained in biopurification systems. This work aimed to assay the effect of oxytetracycline ...
Pesticide dissipation capacity of an organic biomixture used in the agriculture exposed to copper oxychloride
Highlights: • Copper oxychloride addition in a biopurification system was evaluated. • Simultaneous presence copper and pesticides affected slightly its dissipation capacity. • Microbial communities and biological ...
Validation of a methodology by LC-MS/MS for the determination of triazine, triazole and organophosphate pesticide residues in biopurification systems
Biopurification systems are useful in the management of pesticide residues and provide an option to dispose wastewaters of agricultural origin derived from pesticide application practices. The analysis of pesticide residues ...
A microbial consortium from a biomixture swiftly degrades high concentrations of carbofuran in fluidized-bed reactors
An on-farm biopurification system (BPS) biomixture, with proven capacity to degrade carbofuran (CBF) was used as inoculum for a selective-enrichment process to obtain a bacterial consortium capable of using CBF as a sole ...
Biodegradation of Polybrominated Diphenyl Ethersin Liquid Media and Sewage Sludge by Trametes versicolor
Polybrominated diphenyl ethers (PBDE) are widely employed as flame retardants and constitute a group of emerging pollutants of high persistence. The degradation of different PBDE commercial mixtures (penta-, octa- and ...
Ecotoxicological test based on inhibition of fungal laccase activity: Application to agrochemicals and the monitoring of pesticide degradation processes
Ecotoxicological evaluations require the use of assays with several bioindicators from different trophic levels. Only a few ecotoxicological tests using fungi have been developed, reason why, detection of adverse effects ...
First evidence for an aposematic function of a very common color pattern in small insects
Many small parasitoid wasps have a black head, an orange mesosoma and a black metasoma (BOB color pattern), which is usually present in both sexes. A likely function of this widespread pattern is aposematic (warning) ...
Simultaneous removal of neonicotinoid insecticides by a microbial degrading consortium: Detoxification at reactor scale
Neonicotinoid insecticides show high persistence in the environment, and standard biological approaches such as biopurification systems have shown mostly inefficient removal of such compounds. In this work, soil pre-exposed ...
