Biodegradation of fipronil: current state of mechanisms of biodegradation and future perspectives

Fipronil and Fipronil Sulfone Distribution in Chicken Feathers and Eggs after Oral and Dermal Exposure

“…Fipronil solutions can remain stable for about one year at room temperature in standard storage conditions [ 32 ]. However, rapid decomposition of fipronil in its metabolites occurs in the presence of metal ions or under alkaline conditions, indicating possible contamination of the formulations during the production chain [ 32 ].…”

“…Fipronil solutions can remain stable for about one year at room temperature in standard storage conditions [ 32 ]. However, rapid decomposition of fipronil in its metabolites occurs in the presence of metal ions or under alkaline conditions, indicating possible contamination of the formulations during the production chain [ 32 ]. Oral contamination studies have been reported on chicken fed with cyromazine premix (purity 99.8%) or pure fipronil in gelatine capsules [ 23 , 29 ] and on rats with atrazine administrated by oral gavage [ 33 ].…”

New Insights into the Effect of Fipronil on the Soil Bacterial Community

“…For this reason, knowledge of the microbial community in the soil can provide information that favors the search for microorganisms with biotechnological potential, since this ecosystem can be considered the habitat with the greatest bacterial diversity [ 16 , 17 ]. In this sense, the study of the existing microbial community allows not only a better understanding of the ecological dynamics of the soil but also the possibility to search for and exploit microorganisms with promising applications, such as the degradation of recalcitrant compounds [ 18 , 19 , 20 , 21 ].…”

Study of the depuration efficiency and microbiology of biobed systems which receive pesticide contaminated effluents from various agro-food processing units

“…Photo-degradation can only occur on the surface of soil and water systems, the air or the foliage of the treated plants as it is heavily depended on light intensity (Gavrilescu, 2005). Nevertheless, its remediation potential has been studied for plenty PPPs (Huang et al, 2021;Zhou et al, 2021;Mahapatra et al, 2017;Remucal, 2014). Chemical degradation includes different reactions such as ionization, hydrolysis and oxidation-reduction and is usually dependent on the pH of the environmental system.…”

“…Factors influencing microbial degradation include the structure of the microbial community, salinity, carbon and nitrogen sources, presence of oxygen, temperature, soil moisture content and pH (Bhatt et al, 2019;Cycoń et al, 2017;Megharaj and Naidu, 2017;Wu et al, 2014). Biodegradation has been extensively studied for the bioremediation of pesticide-polluted sites (Mishra et al, 2021(Mishra et al, , 2020Cycoń et al, 2017) and many organisms with pesticide degrading abilities have been isolated and characterized (Pandey and Choudhury, 2021;Zhou et al, 2021;Ambreen et al, 2020;Perruchon et al, 2015;.…”
