Optimization of carbofuran insecticide degradation by Enterobacter sp. using response surface methodology (RSM)

Response surface methodology and Plackett-Burman experiments were applied to optimize the biodegradation of carbofuran by using Enterobacter sp. stain BRC05 isolated from selected agricultural areas in peninsular Malaysia. The significant factors influencing the degradation of carbofuran were assessed using two-level Plackett?Burman Design (PBD) with five variables. Plakett Burman experiment showed that the following four variables were significant for carbofuran degradation including, carbofuran concentration, temperature, pH and nitrogen sources. Significant variables obtained in Plackett-Burman Design were further optimize using Central Composite Design (CCD). The outcome of the design for carbofuran degradation for each runs of the PBD experiment base on the design matrix, showed that the minimum and the maximum carbofuran degradation percentage were found to be 6.7% and 79.77% as presented in runs 4 and 1, respectively. Results obtained using Central Composite Design showed that the relations between the factors affect carbofuran degradation with significant response. The predicted results in CCD indicated that highest carbofuran degradation of 95.40% could be realized with carbofuran concentration of 92.50 mg/L, pH of 6.0, temperature 27.50 C, nitrogen sources of 0.45 g/L and reaction period of 6 days. The predicted values were in agreement with the actual values with coefficient of determination with R2 0.9719. Partial 16S rRNA sequence analysis showed that the carbofuran degrading isolate was closely related to members of the genera Enterobacter sp. The morphological and biochemical characteristics of the isolate also confirmed the phylogenetic signature. This study would provide an effective approach that could be beneficial for the bioremediation of carbofuran insecticide in polluted environment.

An analytical strategy for the identification of carbamates, toxic alkaloids, phenobarbital and warfarin in stomach contents from suspected poisoned animals by thin-layer chromatography/ultraviolet detection

In this study, an analytical strategy to identify brucine, strychnine, methomyl, carbofuran (alkaline compounds), phenobarbital, and warfarin (acid compounds) using thin-layer chromatography (TLC) screening with ultraviolet (UV) detection at 254 nm in stomach content is shown. The optimum mobile phase was found to be a chloroform: ethyl acetate: diethylamine (0.5:8.5:1) mixture for alkaline substances while a mixture of chloroform: acetone (9:1) has given better results for acidic substances. As for extraction, an equal proportion between distillated water and crude material (1:1) is required. For alkaline compounds, a filtration system was created in order to avoid any interferences from the biological matrix while for acidic compounds only centrifugation (4000 rpm/10 minutes) was required to obtain an appropriate sample. After the respective pretreatments, a one-step liquid?liquid extraction (LLE) has been employed for alkaline substances using a 3 mL of chloroform: ethyl ether (2:1) mixture for 2 min while acidic analytes used 3 mL of chloroform only during 5 min. For both methodologies described, the respective organic layers were dried down and re-suspended with 50 muL of methanol for further TLC plate application. The methodologies have been developed, successfully validated and applied to gastric contents from real case samples of suspected animal poisoning. Positive results from TLC/UV screening were confronted with HPLC-UV and confirmed by GC-MS.

Electrochemical advanced oxidation of carbofuran in aqueous sulfate and/or chloride media using a flow cell with a RuO2-based anode and an air-diffusion cathode at pre-pilot scale

The treatment of 0.348 mM carbofuran solutions in 0.050 M Na2SO4 at pH 3.0 has been studied by electrochemical oxidation with electrogenerated H2O2 (EO-H2O2), electro-Fenton (EF) and photoelectro-Fenton (PEF). The trials were performed in a 2.5 L pre-pilot plant equipped with a filter-press cell, which contained a RuO2-based anode and an air-diffusion cathode, connected to an annular photoreactor with a 160 W UVA lamp in PEF. The oxidizing species were the [rad]OH generated at the anode from water oxidation and in the bulk from Fenton’s reaction between added Fe2+ and H2O2 produced at the cathode. The oxidation power of treatments rose in the order EO-H2O2 ? EF < PEF, demonstrating the preponderant role of [rad]OH in the bulk. The drug decay always obeyed a pseudo-first order kinetics. Similar TOC abatements of 82%?88% were found in PEF operating at different current densities and carbofuran concentrations, ascribed to the additional photolytic action of UVA light to remove photoactive intermediates, also allowing a gradual detoxification. In matrices with Cl?, active chlorine was also produced as oxidant and its quick reaction with carbofuran caused its faster decay at increasing Cl? content. However, lower mineralization was achieved because of the accumulation of recalcitrant chloroderivatives. GC?MS analysis of treated solutions with 0.070 M NaCl corroborated the formation of 6 chloroderivatives, whereas 5 heteroaromatics were detected in 0.050 M Na2SO4. Oxalic acid was accumulated in the latter medium since its Fe(III) complexes were stable in EF and rapidly mineralized by UVA light in PEF. The mineralization of urban wastewater spiked with carbofuran by PEF in the pre-pilot plant was partial due to the recalcitrant chloroderivatives formed from carbofuran and natural organic matter.

Genetic and metabolic analysis of the carbofuran catabolic pathway in Novosphingobium sp. KN65.2

The widespread agricultural application of carbofuran and concomitant contamination of surface and ground waters has raised health concerns due to the reported toxic effects of this insecticide and its degradation products. Most bacteria that degrade carbofuran only perform partial degradation involving carbamate hydrolysis without breakdown of the resulting phenolic metabolite. The capacity to mineralize carbofuran beyond the benzofuran ring has been reported for some bacterial strains, especially sphingomonads, and some common metabolites, including carbofuran phenol, were identified. In the current study, the catabolism of carbofuran by Novosphingobium sp. KN65.2 (LMG 28221), a strain isolated from a carbofuran-exposed Vietnamese soil and utilizing the compound as a sole carbon and nitrogen source, was studied. Several KN65.2 plasposon mutants with diminished or abolished capacity to degrade and mineralize carbofuran were generated and characterized. Metabolic profiling of representative mutants revealed new metabolic intermediates, in addition to the initial hydrolysis product carbofuran phenol. The promiscuous carbofuran-hydrolyzing enzyme Mcd, which is present in several bacteria lacking carbofuran ring mineralization capacity, is not encoded by the Novosphingobium sp. KN65.2 genome. An alternative hydrolase gene required for this step was not identified, but the constitutively expressed genes of the unique cfd operon, including the oxygenase genes cfdC and cfdE, could be linked to further degradation of the phenolic metabolite. A third involved oxygenase gene, cfdI, and the transporter gene cftA, encoding a TonB-dependent outer membrane receptor with potential regulatory function, are located outside the cfd cluster. This study has revealed the first dedicated carbofuran catabolic genes and provides insight in the early steps of benzofuran ring degradation.
