In this study, we selected and characterized different pesticide-tolerant bacteria isolated from a biomixture of biopurification system that had received continuous applications pesticides mixture. The amplicon analysis reported the phyla Proteobacteria, Firmicutes, Bacteroidetes Actinobacteria were predominant. Six strains grew in presence chlorpyrifos iprodione. Biochemical characterization showed all isolates positive for esterase, acid phosphatase, among others, they identified as...
This work provides the basis for implementing a continuous treatment system using bacterial consortium wastewater containing pesticide mixture of iprodione (IPR) and chlorpyrifos (CHL). Two strains (Achromobacter spanius C1 Pseudomonas rhodesiae C4) isolated from biomixture biopurification were able to efficiently remove pesticides IPR CHL at different concentrations (10 100 mg L-1) liquid medium as individual free consortium. The half-life time (T1/2) was determined However, when used,...
This study provides the basis for implementing a continuous treatment system wastewater containing pesticide mixture formed by atrazine, iprodione, and chlorpyrifos. Two fungal strains (Verticilium sp. H5 Metacordyceps H12) isolated from biomixture of biopurification were able to remove different concentrations (10 50 mg L−1) efficiently liquid medium; however, half-life pesticides was reduced characterized T1/2 5.4 9.2 d 3.7 5.8 2.6 2.9 chlorpyrifos using consortium. The immobilization...
Biopurification systems designed for pesticide treatment are a source of diverse bacteria with environmental and biotechnological applications, including Pseudomonas marginalis C9, which has been reported as biosurfactant-producing bacterium. The optimization biosurfactant produced from P. C9 to enhance the solubility hydrophobic interest was investigated. response surface methodology (RSM) used optimize combined effect initial pH (5–9), agitation (100–300 rpm), temperature (24–32 °C) on...
Dissolved Mn2+ in groundwater is dangerous for human health since it may act as a neurotoxin. To address this issue, sorption has emerged an environmentally-friendly technology removal. This study aimed to assess the effect of activation Chilean natural zeolite, by modification its compensating cations with NaCl, on capacity removal using batch and fixed-bed column studies. The activated zeolites were characterized SEM-EDS, TXRF, XRD, N2 adsorption assays. results studies demonstrate that...
Giant squid hydrolysate (GSH) elaborated from different batches a fishing company was evaluated for cadmium removal. Fixed-bed column packed with iminodiacetic resin as adsorbent used. GSH solution at concentrations were fed in the fixed-bed and breakthrough curves evaluated. A high degree of metal removal achieved saturation point (Ce/C0 ≤ 0.8) more quickly higher cadmium. The maximum capacity adsorption (q0) obtained using Thomas model, where 1137.4, 860.4, 557.4, 203.1 mg g−1 48.37,...
Intensive use of pesticides applied simultaneously in field to improve the effectiveness pest control increase environmental contamination, affecting soil and water quality. Some commonly used are insecticide chlorpyrifos fungicide iprodione; being thus critically essential develop bioremediation methods remove these contaminants by tolerant-bacteria. In this study we selected characterized different pesticides-tolerant bacteria isolated from a biomixture biopurification system that had...
