“…Remediating the environment from the accumulated toxic substances is the focus of a growing number of researches efforts. The degradation or the removal of such pollutants is reported to be conducted through physical, (photo-)chemical, and chemical processes (Katsumata et al, 2011;Reddy and Kim, 2015;Kovács et al, 2016;Hao et al, 2019;Bhat et al, 2020). Microorganisms play a major role in the biological removal of linuron.…”

Phenyl urea herbicides are being extensively used for weed control in both agricultural and non-agricultural applications. Linuron is one of the key herbicides in this family and is in wide use. Like other phenyl urea herbicides, it is known to have toxic effects as a result of its persistence in the environment. The natural removal of linuron from the environment is mainly carried through microbial biodegradation. Some microorganisms have been reported to mineralize linuron completely and utilize it as a carbon and nitrogen source. Variovorax sp. strain SRS 16 is one of the known efficient degraders with a recently sequenced genome. The genomic data provide an opportunity to use a genome-scale model for improving biodegradation. The aim of our study is the construction of a genome-scale metabolic model following automatic and manual protocols and its application for improving its metabolic potential through iterative simulations. Applying flux balance analysis (FBA), growth and degradation performances of SRS 16 in different media considering the influence of selected supplements (potential carbon and nitrogen sources) were simulated. Outcomes are predictions for the suitable media modification, allowing faster degradation of linuron by SRS 16. Seven metabolites were selected for in vitro validation of the predictions through laboratory experiments confirming the degradation-promoting effect of specific amino acids (glutamine and asparagine) on linuron degradation and SRS 16 growth. Overall, simulations are shown to be efficient in predicting the degradation potential of SRS 16 in the presence of specific supplements. The generated information contributes to the understanding of the biochemistry of linuron degradation and can be further utilized for the development of new cleanup solutions without any genetic manipulation.

“…The capacity of bacteria and some plants to detoxify environmental contaminants makes bioremediation technologies as desirable techniques for pesticide remediation. Microbial genera such as Mycobacterium, Pseudomonas, Bacillus, Klebsiella, Pandoraea, Phanerochaete and Chrysosporium are some of the microorganisms that have demonstrated the potential for pesticide bioremediation [40]. These microbes can convert pesticides into less toxic metabolites by employing it as a carbon or nitrogen source, as a source of minerals or as a final electron acceptor in their respiratory chains.…”

Owing to the widespread use of pesticides all over the world and the lack of effective remediation technologies, the persistence of pesticides in the soil has emerged as a serious environmental issue. Although pesticides have a great impact on increasing yield and benefitting cultivators economically, the indiscriminate application of pesticides in croplands has become a threat to the well-being of the natural ecosystems. Pesticides represent one of the most toxic soil pollutants and represent a significant risk to human wellness as well as the natural ecology. The bioremediation process, which utilizes bacteria, fungi, algae, and other organisms, has proved to be one of the most cost-effective and environmentally beneficial solutions to this growing problem. A number of approaches employing bioremediation technologies have successfully been implemented in the field. However, more adaptable, cost effective and easily implementable approaches need to be developed that can deliver the intended outcome. This review elucidates the present status of pesticide contamination and highlights the predominant role played by microbes in pesticide remediation, along with the advances made in recent years.
