Contamination of the environment with polycyclic aromatic hydrocarbons is one of the major problems facing the industrialized nations today. In this work, Pseudomonas stutzeri CET 930 was studied for the first time as bioremediation agent for the degradation of effluents containing phenanthrene, pyrene and benzanthracene, both individually and mixed. The promising results of degradation obtained at flask scale (92, 63 and 94 % in 7 days, respectively) marks the onset of the operation at bench scale bioreactor. The overall biotransformation of phenanthrene, pyrene and benzanthracene in batch operation mode was 95, 78 and 82 % when present individually, and 100, 98 and 100 % when carrying out the biological process in cometabolic conditions, respectively. We have demonstrated the great versatility of this strain for the degradation of structurally different contaminants, such as metal working fluids, polycyclic aromatic hydrocarbons or insecticides such as chlorpyrifos, which makes it a suitable candidate to be applied at industrial scale. In all cases, the experimental data were successfully fitted to models, which turned out to be valuable tools to classify the metabolites involved in the biodegradation process as biomass-related. Since a complete mineralization was pursued, the metabolic pathways of the studied contaminants have been proposed based on gas chromatography-mass spectrometry data.

Dye removal abilities of the mesophilic and thermophilic biomass: a kinetics study

2018

Issue 2

View full text Add to dashboard Cite

Mesophilic biomass and thermophilic biomass samples were isolated and used to remove Dorasyn Red dye from aqueous solutions. The biosorption kinetics of dye uptake by four different types of biomass at three temperatures (20, 30, and 40 °C) were investigated using pseudo-first order kinetics, pseudo-second order kinetics, intraparticle diffusion, Elovich, and Bangham models. The pseudosecond-order kinetics model and the first stage of the intraparticle diffusion model were effective in describing the experimental kinetics data. The biosorption results showed that the mesophilic biomass samples could be useful for removing dye under acidic conditions.

This work assesses the electrocatalytic (EC), photocatalytic (PC), and photoelectroncatalytic degradation (PEC) of Amaranth azo dye with ammonium persulfate (APS). The results were observed that the photoelectrocatalytic degradation technique more efficient than other techniques. The effects of operational parameters such as initial pH and APS concentrations on color removal efficiency were investigated. Decolorization and degradation were found to depend strongly on the system parameters. The dye decolorization was enhanced using pH 2.0. The rate of degradation of Amaranth with APS followed pseudo-first order kinetics in the dye concentration. Decolorization efficiency (%) and degradation rates of amaranth were increase with increasing APS concentration.
