Cellular immobilisation (CI) is a method characterised by restricting the cells to a delimited area while preserving their metabolic, catabolic, and catalytic activities Biodegradation of contaminants is one of the potential applications of CI. Immobilised cells can achieve to degrade the degradation of toxic substances with higher efficiency than cells in a free state. free cells. The aim of this work was to compile the most important aspects of CI as a strategy for the degradation of pesticides. We discuss the main targeted chemical substances, the used microorganisms, materials, and techniques, as well as their advantages, and limitations We highlight increases in the percentage of degradation, greater stability, protection, and tolerance to pesticides when a CI strategy is implemented. Finally, the requirements for deepening our understanding of the involved kinetic, molecular, and transfer processes are discussed, particularly for their application in situ.

This study examined the photodecomposition of carbofuran, a carbamate pesticide with high oral toxicity. Rate constants are measured for the pesticide in aqueous solution and in the presence of various samples of dissolved organic matter (DOM). Kinetic experiments are monitored with HPLC, while reaction products are determined using HPLC, GC-MS, and 1H NMR: mechanisms are proposed for the first three steps of the reaction. It was found that the photodecomposition proceeds via first-order reaction kinetics and that the presence of various DOM samples inhibits the photolysis reaction of carbofuran. This phenomenon can be correlated to the magnitude of the binding interaction between carbofuran and DOM. Finally, techniques such as GC-MS and 1H NMR are used to identify the photodecomposition products. The first three steps of the reaction are defined. In the first step of the reaction, the carbamate group is cleaved from the molecule. The furan moiety is opened in the second step producing a substituted catechol with a tert-butyl alcohol group as the substituent at the number three carbon. This molecule then undergoes a dehydration reaction to form an alkene side group from the tert-butyl alcohol side group.

Application of 1563-38-8, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other?

The influence of repeated annual field applications of the insecticide-nematicide carbofuran on carbofuran-degrading microbial communities was studied at a site in Florida that exhibited enhanced degradation toward the chemical. Three successive annual applications of carbofuran at 4.5 kg ha-1 y-1 did not result in an increase in the size of the microbial community capable of mineralizing uniformly ring-labeled 14C-carbofuran (carbofuran-ring degraders) in surface soil (0-15 cm depth). After the second annual application, however, the community capable of mineralizing carbonyl-labeled 14C-carbofuran (carbofuran hydrolyzers) in the treated surface soil was significantly larger than that after the first annual application. Communities of methylamine utilizers in treated and untreated soils were much larger than the communities of carbofuran phenol degraders, but not statistically different from the sizes of carbofuran hydrolyzers. In addition to no increase in the number of carbofuran ring degraders in the treated site during three consecutive annual applications of carbofuran, laboratory addition of 10 mug carbofuran g-1 to treated and untreated soils collected in 1995 did not result in an increase in the number of carbofuran ring degraders. This suggests that degradation of the ring structure of carbofuran in soil is a cometabolic process.

The degradation of two pesticides, carbofuran (CBF) and ioprodine (IPR), was studied by the photolytic decomposition of hydrogen peroxide (UV/H2O2). The influence of two experimental parameters, H2O2 concentration and initial pH, as well as their interactions, was investigated. Optimization was carried out where experimental parameters were determined for the treatment of each pesticide. Both pesticides were totally eliminated by UV/H2O2 system under optimal conditions. However, significant differences were found: CBF degradation was influenced by both parameters and their interactions, while IPR degradation was not statistically affected by initial pH. Interestingly, analysis of degradation pathways showed a major influence of photolysis process and oxidation due to hydrogen peroxide for the CBF degradation, while the synergistic combination between both of them played the most relevant role during IPR degradation. A mixture of both pesticides was also submitted to UV/H2O2 action in which a lower rate was observed for IPR elimination while CBF was not affected. A 90 % of chemical oxygen demand (COD) was removed and 75 % of mineralization was achieved after the treatment of the mixture. Almost 92 % of the toxicity was eliminated making this technique a promising process to treat toxic mixtures of these pesticides.

The photo-Fenton process is intensified for degradation of carbofuran by using a tubular microreactor coiled around a florescent light. The microreactor attained 7.5 times faster degradation rate compared to a batch reactor operated under a LED light. At the initial Fe2+ concentration of 0.25 mM, the degradation rates in the batch reactor were fast at first, subsequently became slow, and afterward gradually increased with time regardless of light intensity. In the microreactor, the degradation rates appeared to decrease similarly to the first-order reaction despite the same initial Fe2+ concentration. A proposed kinetic model well fitted the results of both batch and microreactors by modeling that Fe3+ is photoreduced in a complex in equilibrium with Fe3+ and intermediates with carboxyl group decomposed from carbofuran.
