Microbial Degradation of Aldrin and Dieldrin: Mechanisms and Biochemical Pathways

Frontiers in Microbiology, Journal Year: 2022, Volume and Issue: 13

Published: March 29, 2022

As members of the organochlorine group insecticides, aldrin and dieldrin are effective at protecting agriculture from insect pests. However, because excessive use a long half-life, they have contributed to major pollution water/soil environments. Aldrin been reported be highly toxic humans other non-target organisms, so their has gradually banned worldwide. Various methods tried remove them environment, including xenon lamps, combustion, ion conversion, microbial degradation. Microbial degradation is considered most promising treatment method its advantages economy, environmental protection, convenience. To date, few aldrin/dieldrin-degrading microorganisms isolated identified, Pseudomonas fluorescens, Trichoderma viride, Pleurotus ostreatus, Mucor racemosus, Burkholderia sp., Cupriavidus Pseudonocardia community anaerobic microorganisms. Many aldrin/dieldrin resistance genes identified insects microorganisms, such as Rdl, bph, HCo-LGC-38, S2-RDLA302S , CSRDL1A, CSRDL2S, HaRdl-1, HaRdl-2. includes three pathways: oxidation pathway, reduction hydroxylation with metabolite. Degradation four oxidation, reduction, hydroxylation, hydrolysis, 9-hydroxydieldrin dihydroxydieldrin products. studies investigated toxicity aldrin/dieldrin. reviews focused on biochemical mechanisms In this review paper, summarized in order provide theoretical practical basis for bioremediation aldrin/dieldrin-polluted environment.

Remediation technologies for neonicotinoids in contaminated environments: Current state and future prospects

Environment International, Journal Year: 2023, Volume and Issue: 178, P. 108044 - 108044

Published: June 16, 2023

Neonicotinoids (NEOs) are synthetic insecticides with broad-spectrum insecticidal activity and outstanding efficacy. However, their extensive use persistence in the environment have resulted accumulation biomagnification of NEOs, posing significant risks to non-target organisms humans. This review provides a summary research history, advancements, highlighted topics NEOs remediation technologies mechanisms. Various approaches been developed, including physiochemical, microbial, phytoremediation, microbial physicochemical being most extensively studied. Recent advances physiochemical led development innovative adsorbents, photocatalysts, optimized treatment processes. High-efficiency degrading strains well-characterized metabolic pathways successfully isolated cultured for remediation, while many plant species shown great potential phytoremediation. challenges gaps remain this field. Future should prioritize isolating, domesticating or engineering high efficiency, NEO degradation, as well developing synergistic techniques enhance removal efficiency on multiple varying concentrations different environmental media. Furthermore, shift from pipe-end pollution prevention strategies is needed, green economically efficient alternatives such biological insecticides. Integrated case-specific that can be applied practical projects need along clarifying degradation mechanisms improve efficiency. The successful implementation these will help reduce negative impact human health.

Mitigation of Imidacloprid Toxicity in Poultry Chicken by Selenium Nanoparticles: Growth Performance, Lipid Peroxidation, and Blood Traits

Biological Trace Element Research, Journal Year: 2023, Volume and Issue: 201(11), P. 5379 - 5388

Published: Feb. 15, 2023

Abstract Imidacloprid is an insecticide that protects against insects in the agriculture, animal, and poultry production sectors. Since accumulation of imidacloprid induces adverse impacts on general health status quality food chain, this study tested broilers. Besides, selenium nanoparticles were fed to birds relieve negative growth performance status. Birds (1-day age, initial weight 46.05 ± 1.0 g) divided into four groups (triplicates) where 15 chicks each replicate (45 for group). The first group (control) was basal diet without either or toxicity. second nano form at 3 mg/kg. third exposed 1/10 LT 50 (3 mg/kg body weight). fourth mg/kg) All kept under same conditions 35 days. final gain showed marked improvement compared imidacloprid-exposed group, while feed intake conversion ratio markedly reduced. red blood cells higher values than control those imidacloprid. Interestingly, hemoglobulin hematocrit increased with exposure. Furthermore, white total protein, albumin, globulin feeding. had aspartate aminotransferase (AST), alanine (ALT), malondialdehyde levels remaining groups. Accordingly, dietary are suggested broiler cope effects
