“…Bio-stimulation can be performed by providing the necessary nutrients or electron acceptors, such as oxygen or nitrate, to promote the proliferation of indigenous microbes. Aldas-Vargas et al [ 110 ] investigated the biodegradation of herbicides, namely, mecoprop-p and 2,4-dichlorophenoxyacetic acid (2,4-D), in groundwater. They concluded that bio-stimulation with oxygen and dissolved organic carbon had the potential for field application.…”

The bioremediation of heavy metal ions and pesticides is both cost-effective and environmentally friendly. Microbial remediation is considered superior to conventional abiotic remediation processes, due to its cost-effectiveness, decrement of biological and chemical sludge, selectivity toward specific metal ions, and high removal efficiency in dilute effluents. Immobilization technology using biochar as a carrier is one important approach for advancing microbial remediation. This article provides an overview of biochar-based materials, including their design and production strategies, physicochemical properties, and applications as adsorbents and support for microorganisms. Microorganisms that can cope with the various heavy metal ions and/or pesticides that enter the environment are also outlined in this review. Pesticide and heavy metal bioremediation can be influenced by microbial activity, pollutant bioavailability, and environmental factors, such as pH and temperature. Furthermore, by elucidating the interaction mechanisms, this paper summarizes the microbe-mediated remediation of heavy metals and pesticides. In this review, we also compile and discuss those works focusing on the study of various bioremediation strategies utilizing biochar and microorganisms and how the immobilized bacteria on biochar contribute to the improvement of bioremediation strategies. There is also a summary of the sources and harmful effects of pesticides and heavy metals. Finally, based on the research described above, this study outlines the future scope of this field.

“…In bio-stimulation, naturally occurring microorganisms are employed in degrading pollutants such as hydrocarbons, pesticides etc. Scientists have proven that bio-stimulation has a real potential as a technology for remediating contaminants in soil and water environments (Andreolli et al, 2015;Aldas-Vargas et al, 2021). If the natural degradation does not happen or it is very slow, a stimulation of natural microbial degradation is achieved by supplying some nutrients such as, nitrogen, phosphorus and oxygen like electron acceptors required for the microbial activity (Boopathy, 2000;Iwamoto and Nasu, 2001).…”

Purpose: Scientists have identified a plenty of bacterial strains having ability to degrade pesticide residues accumulated in the environment. Due to wide variation of chemical properties of pesticides, a single strain may not be versatile. Hence, identification of bioremediation ability of various bacteria is important. This review focused on understanding and explaining the role of soil bacteria having pesticide detoxification ability.Methodology: Previous research articles, book chapters and literature on bioremediation ability of different soil bacteria were reviewed and various strains of soil bacteria having bioremediation ability, mechanisms behind microbial bioremediation, factors affecting bioremediation and limitations and recent advancements of bioremediation were identified. Based on identified research gaps, further perspectives were introduced. Findings:The results revealed that plenty of soil bacteria having a bioremediation potential have been identified worldwide. As the major mechanism of bioremediation, the microorganisms consume pesticidecontaminated in the soil as their energy or nutrient sources. Various factors such as Bioavailability, Substrate and Environmental factors effect on bioremediation potential. Biostimulation, Bioaugmentation, Biopiling, Composting, Bioreactors and Land farming are identified as popular bioremediation methods suiTable 0for the bioremediation of pesticide contaminants. However, this technique still remains partially developed due to the lack of versatile microorganisms for detoxifying variety of different pesticides.

“…Additional carbon sources, occurring for instance in the low molecular weight fraction of DOM, may therefore be important for the survival of OMP degraders due to commonly low OMP concentrations, 25,26 and can, for example, play an import role in bio-augmentation processes. 14,27,28 However, the substrate specicity of common OMP degraders, i.e. their ability to biodegrade substrates from different compound classes compared to their natural substrates (OMPs), remains poorly investigated.…”

“…31,32 Therefore, studies investigating OMP-DOM interactions oen use complex environmental samples to represent DOM and indigenous communities. 14,15,24,28 While this approach has high environmental representativeness, experiments based on pure cultures and dened carbon sources can clarify the detailed interplay of chemical structures and substrate bioavailability. A systematic comparison of the substrate range of commonly specialized OMP degraders to reference strains with a broad metabolic repertoire, i.e.…”
