“…The methylamine generated is utilised as a C and N source by strain SP1a. Whereas the 2-isopropoxyphenol was proposed to be utilised through the formation of catechol by the strain SP1b (Kim et al, 2017; Figure 3). Earlier, propoxur hydrolase activity has been reported in the cell-free extract of a propoxur degrading Pseudomonas (Kamanavalli and Ninnekar, 2000).…”

“…SP1a and Nocardioides sp. SP1b, based on spent media analysis and whole-cell biotransformation studies ( Kim et al, 2017 ). The strain SP1a harbours carbamate hydrolase, which catalyses the hydrolysis of propoxur to 2-isopropoxyphenol, methylamine and CO 2 .…”

“…Besides Carbaryl, recently it has been shown to act on Carbofuran with low efficiency ( Yan et al, 2018 ). Homologs of this hydrolase have been found to act on various other carbamate pesticides like propoxur, oxamyl and fenobucarb, amongst others ( Kim et al, 2014 , 2017 ; Rousidou et al, 2016 ). For example, the CaH of Novosphingobium sp.…”

Carbamate pesticides are widely used as insecticides, nematicides, acaricides, herbicides and fungicides in the agriculture, food and public health sector. However, only a minor fraction of the applied quantity reaches the target organisms. The majority of it persists in the environment, impacting the non-target biota, leading to ecological disturbance. The toxicity of these compounds to biota is mediated through cholinergic and non-cholinergic routes, thereby making their clean-up cardinal. Microbes, specifically bacteria, have adapted to the presence of these compounds by evolving degradation pathways and thus play a major role in their removal from the biosphere. Over the past few decades, various genetic, metabolic and biochemical analyses exploring carbamate degradation in bacteria have revealed certain conserved themes in metabolic pathways like the enzymatic hydrolysis of the carbamate ester or amide linkage, funnelling of aryl carbamates into respective dihydroxy aromatic intermediates, C1 metabolism and nitrogen assimilation. Further, genomic and functional analyses have provided insights on mechanisms like horizontal gene transfer and enzyme promiscuity, which drive the evolution of degradation phenotype. Compartmentalisation of metabolic pathway enzymes serves as an additional strategy that further aids in optimising the degradation efficiency. This review highlights and discusses the conclusions drawn from various analyses over the past few decades; and provides a comprehensive view of the environmental fate, toxicity, metabolic routes, related genes and enzymes as well as evolutionary mechanisms associated with the degradation of widely employed carbamate pesticides. Additionally, various strategies like application of consortia for efficient degradation, metabolic engineering and adaptive laboratory evolution, which aid in improvising remediation efficiency and overcoming the challenges associated with in situ bioremediation are discussed.

P ESTICIDES play an important role in preventing insect pests and weeds in crops. However, excessive use of pesticides has been known to be unsafe, due to their toxicity to non-target organisms and the ecosystem. Biodegradation is an innovative approach for decontaminating pesticide pollution. However, compared with the list of extensively used pesticides there are few well-characterized strains of microbes that transform pesticides into less-toxic or more labile products at environmentally useful rates. Fortunately, the technology required to isolate and characterize such microbial strains has improved immensely in the recent years. Furthermore, recent experimental developments have made practical the modification of potentially beneficial biodegradation genes so that they may be optimally expressed in a wide range of microbial species. This reviews article explore the recent studies that have focused on biodegradation of pesticide residues, the mechanism of microbial degradation of pesticides, the factors that affect the degradation of pesticides and the new application of microbial degradation of pesticides.
