“…Every day, increasing environmental pollution affects many living organisms and has always been considered a critical challenge in the scientific community (Niroumand et al, 2016). The high accumulation of pesticides in agricultural soils and their cumulative behavior and toxicity pose severe threats to 10.3389/fmicb.2022.979383 beneficial plants (Ferrando and Matamoros, 2020). It is well known that the accumulation of pesticides affects the behavior of soil microbial species and enzymes and is absorbed by plants, which further transfers it to non-target organisms through the food chain process (Sayed et al, 2020).…”

Synthetic pesticides are extensively and injudiciously applied to control agriculture and household pests worldwide. Due to their high use, their toxic residues have enormously increased in the agroecosystem in the past several years. They have caused many severe threats to non-target organisms, including humans. Therefore, the complete removal of toxic compounds is gaining wide attention to protect the ecosystem and the diversity of living organisms. Several methods, such as physical, chemical and biological, are applied to degrade compounds, but as compared to other methods, biological methods are considered more efficient, fast, eco-friendly and less expensive. In particular, employing microbial species and their purified enzymes makes the degradation of toxic pollutants more accessible and converts them into non-toxic products by several metabolic pathways. The digestive tract of insects is usually known as a superior organ that provides a nutrient-rich environment to hundreds of microbial species that perform a pivotal role in various physiological and ecological functions. There is a direct relationship between pesticides and insect pests: pesticides reduce the growth of insect species and alter the phyla located in the gut microbiome. In comparison, the insect gut microbiota tries to degrade toxic compounds by changing their toxicity, increasing the production and regulation of a diverse range of enzymes. These enzymes breakdown into their derivatives, and microbial species utilize them as a sole source of carbon, sulfur and energy. The resistance of pesticides (carbamates, pyrethroids, organophosphates, organochlorines, and neonicotinoids) in insect species is developed by metabolic mechanisms, regulation of enzymes and the expression of various microbial detoxifying genes in insect guts. This review summarizes the toxic effects of agrochemicals on humans, animals, birds and beneficial arthropods. It explores the preferential role of insect gut microbial species in the degradation process and the resistance mechanism of several pesticides in insect species. Additionally, various metabolic pathways have been systematically discussed to better understand the degradation of xenobiotics by insect gut microbial species.

“…In the batch experiment, the removal efficiency was around 87% with an immobilized system. In continuous mode, the efficiency was higher in the case of the luffa system which was 95%, 93%, and 82% for sulfacetamide, sulfamethazine, and sulfamethoxazole respectively (Ferrando and Matamoros, 2020). The benefit of immobilization with microalgabacteria consortia for the removal of sulfamethoxazole (SMX) from anaerobically digested centrate (ADC) was exploited by .…”
