“…For the goethite and HA-goethite complex systems, peak intensities declined compared with the spectrum of mineral-free bacterial cells on ZnSe, probably owing to the presences of mineral suspensions ( Figures 3B,C ). Compared to the HA-goethite complex system, more adsorption bands were observed in the range of 1800–1000 cm -1 in the goethite system, which due likely to the formation of chemical bonds between the catabolic intermediates of MP (i.e., paraoxon, dimethylthiophosphoric acid, p -nitrophenol, 4-nitrocatechol, and 1,2,4-benzenetriol) and Fe or hydroxyl groups on the surface of goethite ( Figures 3B,C ; Rani and Lalithakumari, 1994 ; Pakala et al, 2007 ; Tiwari et al, 2017a , b ). For example, the emerging bands at 1106 and 1071 cm -1 were reported earlier from IR spectra of P adsorbed on Fe oxides ( Tejedortejedor and Anderson, 1990 ; Hong et al, 2016 ).…”

Microbial degradation plays an essential role in the removal of hydrophobic organic compounds (HOCs) dispersed in soil and sediment, and its performance is greatly affected by mineral particles which regulate HOCs bioavailability by interfacial adsorption. Likewise, bacteria cells attach to the surfaces of mineral particles as well but how bacterial attachment affects biodegradation is largely unknown. Here we report inhibitory effects of goethite and humic acid (HA)-goethite complex addition on microbial degradation of methyl parathion (MP). Using attenuated total reflectance-Fourier transform infrared spectroscopy, we observed that the adhesion of bacterial cells responsible for MP degradation on goethite occurred and the adhesive strength increased over time. We then replaced goethite with phosphate-adsorbed goethite to weaken the goethite-bacteria association and the inhibition of MP biodegradation was alleviated. These results suggested the formation of goethite-bacteria association hinder MP biodegradation. Meanwhile, our results showed that HA coating prevented bacterial attachment on goethite particles along with a drastically increased MP adsorption by goethite. The combined effect would lead to decreased mass fluxes of MP to bacterial cells and could represent another mechanism responsible for the decreased degradation rate observed in the current study.

“…Isolation of atrazine-biodegrading species from herbicides containing wastewater was characterized by 16S rRNA [96]. The thermal cycle operated at 94 o C for 5 min for initial denaturation, followed by 35 and characterized by 16S rRNA for pesticides such as DDT, endosulfane, lindane, parathion, malathion, and methyl parathion, as given in Table 5 [29,[98][99][100][101][102].…”

The increasing use of various pesticides (e.g., organophosphate, organochlorine, carbamates, and pyrethroid) has helped to improve agricultural productivity by minimizing the potential crop losses associated with insect attacks. Owing to their highly recalcitrant nature, most pesticides and their residues often accumulate in the environment to exert deleterious effects on human health and various ecosystems. Among a variety of remediation options, biological approaches have attracted a widespread attention for the treatment of pesticide in soil/water systems due to their environmentally benign nature. In this regard, this review article was organized to highlight the recent advancements in the application of various bioremediation approaches for the degradation/removal of pesticides from soil/water matrixes along with the catabolic capacity of microorganisms. Our discussions were expanded further to emphasize identification of specific bacterial communities/strains, such as Bacillus sp. and Pseudomonas sp. This review is expected to provide an overview of the modern biotechnological methodologies along with the associated merits and hurdles for the effective abatement of pesticides.

“…It consumed long time to incubate the cyanobacterial and the incubation was affected by the presence of light. The incubation of cyanobacterial only carried out in the light condition [60]. It is not suitable for huge MP manufacturing industries as the rate of bacterial incubation is lower than the rate of wastewater production.…”

Organophosphates (OPs) are insecticide used to replace the persistence organochlorines (OCs). OPs are the effective insecticide used to control pests to enhance crops productions. Due to the strong recalcitrant properties, OPs cannot totally be degraded by conventional wastewater treatment process and the effluent causes negative impacts to the environment. The effectiveness of the AOPs is relied on the strong radical namely hydroxyl radicals (•OH) which can convert the pollutants into less harmful products. Photocatalysis is one of the AOPs widely practiced in water treatment process. A good photocatalyst must able to promote the electron from its valance band to the conduction band and the prevent the photogenerated electrons from returning to its valance band. The electron generated was further reacted with oxygen to form peroxyl radicals, •O2-. The hole (h+) formed was then react with water molecule to form •OH. Titanium dioxide, TiO2 is well known photocatalyst which only can be activated under ultra-violet light. Visible light photocatalysts are in the current research trend as they are found to be an effective method to degrade contaminants in wastewater. Various type of dopants has been doped on the TiO2 with different method purposely to shift the absorption of light from the UV light region to visible light region. The purpose of this review is to present the studies on different preparation method of the modified TiO2 and application of the modified TiO2 in degrading different types of OP pesticides. Finally, the need for present and further research on OPs wastewater also briefly discussed.
