Chemical herbicides are widely used to control weeds and are frequently detected as contaminants in the environment. Due to their toxicity, the environmental fate of herbicides is of great concern. Microbial catabolism is considered the major pathway for the dissipation of herbicides in the environment. In recent decades, there have been an increasing number of reports on the catabolism of various herbicides by microorganisms. This review presents an overview of the recent advances in the microbial catabolism of various herbicides, including phenoxyacetic acid, chlorinated benzoic acid, diphenyl ether, tetra-substituted benzene, sulfonamide, imidazolinone, aryloxyphenoxypropionate, phenylurea, dinitroaniline, s-triazine, chloroacetanilide, organophosphorus, thiocarbamate, trazinone, triketone, pyrimidinylthiobenzoate, benzonitrile, isoxazole and bipyridinium herbicides. This review highlights the microbial resources that are capable of catabolizing these herbicides and the mechanisms involved in the catabolism. Furthermore, the application of herbicide-degrading strains to clean up herbicide-contaminated sites and the construction of genetically modified herbicide-resistant crops are discussed.

Visible-light photocatalysis boosted by Z-scheme photocatalysts has been deemed as an economic and effective way in eliminating emerging antibiotics pollution. A Z-scheme heterojunction photocatalyst g-C3N4@PDA/BiOBr (CNPB) was hereby facilely constructed through polydopamine (PDA) modification of g-C3N4 followed by deposition of BiOBr component via a solvothermal reaction. The structure, morphology, optical and photoelectrochemical properties etc. of CNPB were characterized and explored. The photocatalytic activity of CNPB was assessed on the degradation of sulfamethoxazole (SMX). CNPB manifested remarkably improved photocatalytic performance than the as-prepared g-C3N4, BiOBr and g-C3N4/BiOBr heterojunction in the degradation of SMX under visible light irradiation. SMX could be nearly completely degraded in 60 mins by CNPB, while the degradation rate of SMX under g-C3N4, BiOBr, g-C3N4/BiOBr heterojunction, and the ?g-C3N4@PDA + BiOBr? mixture were 30%, 42%, 71%, and 47%, respectively. The highly enhanced photocatalytic efficiency of CNPB was attributed to the synergistic effect of improved light harvesting and accelerated transport and separation of photo-generated carriers in the Z-scheme structure with PDA as efficient electron transfer mediators. A Z-scheme charge transfer mechanism was confirmed by experiments on radical scavenging and electron spin resonance (ESR) signals trapping, which demonstrated that the h+ and [rad]O2? were the major reactive species in oxidizing SMX. The degradation mechanism, main intermediates and reaction pathways were further explored. Besides, CNPB exhibited good stability and reusability in multiple uses. The construction of Z-scheme photocatalyst using biomimetic polydopamine as electron transfer mediators may provide an insight into designing new and efficient photocatalysts for environmental applications.

This work presents ferrate(VI) (FeVIO42-, FeVI) oxidation of a wide range of sulfonamide antibiotics (SAs) containing five- and six-membered heterocyclic moieties (R) in their molecular structures. Kinetics measurements of the reactions between FeVI and SAs at different pH (6.5-10.0) give species-specific second-order rate constants, k5 and k6 of the reactions of protonated FeVI (HFeO4-) and unprotonated FeVI (FeVIO42-) with protonated SAs (HX), respectively. The values of k5 varied from (1.2 ± 0.1) × 103 to (2.2 ± 0.2) × 104 M-1 s-1, while the range of k6 was from (1.1 ± 0.1) × 102 to (1.0 ± 0.1) × 103 M-1 s-1 for different SAs. The transformation products of reaction between FeVI and sulfadiazine (SDZ, contains a six-membered R) include SO2 extrusion oxidized products (OPs) and aniline hydroxylated products. Comparatively, oxidation of sulfisoxazole (SIZ, a five-membered R) by FeVI has OPs that have no SO2 extrusion in their structures. Density functional theory calculations are performed to demonstrate SO2 extrusion in oxidation of SDZ by FeVI. The detailed mechanisms of oxidation are proposed to describe the differences in the oxidation of six- and five-membered heterocyclic moieties (R) containing SAs (i.e., SDZ versus SIZ) by FeVI.

A series of [[(4,5-dihydro-2-oxazolyl)phenoxy]alkyl]isoxazoles has been synthesized and evaluated as antipicornavirus agents. The effect of alkyl groups in the 4- and 5-position of the oxazoline ring, as well as the alkyl chain length, on antiviral activity was examined. Compound 14 was evaluated in vivo and was found to signigicantly reduce mortality at an oral dose of 4 mg/kg in mice infected intracerebrally with poliovirus-2. Compound 14 was also effective in preventing paralysis when administered intraperitoneally to mice infected subcutaneously with a lethal dose of ECHO-9 virus. On the basis of the results of these studies, compound 14 is a strong candidate for clinical evaluation as a systemic agent for the treatment of picornavirus infections.

In this article, heat-activated persulfate oxidation was investigated as a promising technique for the removal of sulfamethoxazole from an aqueous environment. It was found that the degradation efficiency of sulfamethoxazole increases with increasing persulfate concentration due to the increased [rad]SO4? production. As suggested by the Arrhenius equation, the sulfamethoxazole degradation rate constant increased with increasing temperature. An activation energy of 103 kJ/mol was determined. Furthermore, the initial pH of the reaction mixture had a large influence on the degradation of sulfamethoxazole. At higher initial pH values, the degradation of sulfamethoxazole increased. The main cause for this increase is a difference in sulfamethoxazole distribution: at higher pH, the deprotonated form of sulfamethoxazole is present and found to be more susceptible to degradation. A second reason was found to be the formation of [rad]OH at higher initial pH values, although this contribution was smaller. To elucidate the degradation process, six intermediates were identified, and the difference in formation of these compounds at different initial pH values was revealed. Through ECOSAR modeling, some degradation products were found to be of main interest when monitoring the toxicity of the degradation mixture.
