“…The detoxification of OPP can be realized using various physio-chemical approaches (oxidation, electrochemical methods, sonolysis, photocatalytic degradation, etc.) [ 42 , 43 ] and biological (enzymatic or/and microbial) [ 20 ] methods. The biological degradation of OPP with the participation of microorganisms looks more attractive from the ecological point of view since cells can effectively remove pesticides from contaminated sources and involve them in deep conversion through regular metabolism.…”

“Unity and Struggle of Opposites” as a Basis for the Functioning of Synthetic Bacterial Immobilized Consortium That Continuously Degrades Organophosphorus Pesticides

et al. 2022

This work was aimed at the development of an immobilized artificial consortium (IMAC) based on microorganisms belonging to the Gram-positive and Gram-negative bacterial cells capable of jointly carrying out the rapid and effective degradation of different organophosphorus pesticides (OPPs): paraoxon, parathion, methyl parathion, diazinon, chlorpyrifos, malathion, dimethoate, and demeton-S-methyl. A cryogel of poly(vinyl alcohol) was applied as a carrier for the IMAC. After a selection was made between several candidates of the genera Rhodococcus and Pseudomonas, the required combination of two cultures (P. esterophilus and R. ruber) was found. A further change in the ratio between the biomass of the cells inside the granules of IMAC, increasing the packing density of cells inside the same granules and decreasing the size of the granules with IMAC, gave a 225% improvement in the degradation activity of the cell combination. The increase in the velocity and the OPP degradation degree was 4.5 and 16 times greater than the individual P. esterophilus and R. ruber cells, respectively. Multiple uses of the obtained IMAC were demonstrated. The increase in IMAC lactonase activity confirmed the role of the cell quorum in the action efficiency of the synthetic biosystem. The co-inclusion of natural strains in a carrier during immobilization strengthened the IMAC activities without the genetic enhancement of the cells.

“…The reduction of pesticide residues during fermentation has been studied in various food products [ 72 , 73 , 74 , 75 , 76 , 77 ]. Microorganisms with the highest pesticide degradation activity belong to the genera Bacillus, Micrococcus, Arthrobacter, Corynebacterium, Flavobacterium, Pseudomonas , and Rhodococcus , as well as fungi from the genera Penicillium, Aspergillus, Fusarium , and Trichoderma [ 78 , 79 , 80 ]. Although fungal bioremediation of pesticides has significant potential, it has received less attention than bacterial bioremediation.…”

The treatment of agricultural areas with pesticides is an indispensable approach to improve crop yields and cannot be avoided in the coming decades. At the same time, significant amounts of pesticides remain in food and their ingestion causes serious damage such as neurological, gastrointestinal, and allergic reactions; cancer; and even death. However, during the fermentation processing of foods, residual amounts of pesticides are significantly reduced thanks to enzymatic degradation by the starter and accompanying microflora. This review concentrates on foods with the highest levels of pesticide residues, such as milk, yogurt, fermented vegetables (pickles, kimchi, and olives), fruit juices, grains, sourdough, and wines. The focus is on the molecular mechanisms of pesticide degradation due to the presence of specific microbial species. They contain a unique genetic pool that confers an appropriate enzymological profile to act as pesticide detoxifiers. The prospects of developing more effective biodetoxification strategies by engaging probiotic lactic acid bacteria are also discussed.

“…Organophosphates (OPs) are esters of pentavalent phosphorous acid, displaying an extensive spectrum of toxicity in living beings. Chlorpyrifos (CP) is a category of organophosphorus pesticides (OP), that find many applications as insecticide, acaricide and termiticide (Akhtar et al 2009, Nandhini et al 2021. Chlorpyrifos (CP), an organophosphorus insecticide (OP), commonly consumed in public health and agriculture, has a high octanol water partition coefficient (K ow = 4.70) (Osman et al 2014).…”

“…The aqueous hydrolysis DT50 and photolysis of CP are up to 72 d and 29.6, respectively (Zhu et al 2021). The characteristics of extensive use of CP are long-range transport potential, high lipophilicity, bioaccumulation, and extension of CP half-life leading to slow degradation and high toxicity (Nandhini et al 2021). Concentrations of CP detected in both surface and groundwater ranged between 0.13 μg/L to 0.24 μg/L (Qurie et al 2016).…”

The current paper focuses on assessing key parameters affecting the extraction of Chlorpyrifos as well as emulsion stability using the emulsion liquid membrane technology. Five parameters affecting the extraction have been studied: homogenizer speed, emulsification time, agitating time, surfactant concentration, and stripping phase concentration taking into consideration the emulsion breaking. Experiments proved that using the resulting optimum values will maximize both extraction and stripping efficiencies (93.8% and 94.7% respectively), while minimizing the emulsion breakage (increasing the stability of emulsion) to 0.73% with no need to employ a carrier agent. A 10 min agitating time, 3% (v/v) Span 80 as a surfactant, 12700-rpm homogenizer speed, 0.25 M HCl as an internal phase concentration, and 5 min emulsification time are chosen to be the optimum parameters' values. A study of extraction kinetics and estimation of mass transfer coefficient was also accomplished (3.89×10 -9 m/s). The conclusions of this work can be extended to the removal of other types of pesticides from water.
