“…On the other hand, metagenomic approaches allow elucidating the microbial interaction at the contaminated site or during mycoremediation without the need for microbial cultivation [58,145]. Metagenomic analysis of total DNA from contaminated environmental samples allows the screening of metabolite-producing fungi applied to remediation through genomic data mining or functional screening of specific genes [172,173]. However, metagenomic studies on fungi remain sparsely explored, and the results of annotated sequences for eukaryotes is much lower than for bacteria [173].…”

Petroleum hydrocarbons and toxic metals are sources of environmental contamination and are harmful to all ecosystems. Fungi have metabolic and morphological plasticity that turn them into potential prototypes for technological development in biological remediation of these contaminants due to their ability to interact with a specific contaminant and/or produced metabolites. Although fungal bioinoculants producing enzymes, biosurfactants, polymers, pigments and organic acids have potential to be protagonists in mycoremediation of hydrocarbons and toxic metals, they can still be only adjuvants together with bacteria, microalgae, plants or animals in such processes. However, the sudden accelerated development of emerging technologies related to the use of potential fungal bioproducts such as bioinoculants, enzymes and biosurfactants in the remediation of these contaminants, has boosted fungal bioprocesses to achieve higher performance and possible real applications. In this review, we explore scientific and technological advances in bioprocesses related to the production and/or application of these potential fungal bioproducts when used in remediation of hydrocarbons and toxic metals from an integral perspective of biotechnological process development. In turn, it sheds light to overcome existing technological limitations or enable new experimental designs in the remediation of these and other emerging contaminants.

“…Most research on biosurfactant producing microbes has been limited to soil isolates, primarily from the Pseudomonas and Bacillus species. However, with the help of metagenomics, it has recently been discovered that a diverse group of soil and marine microbes can produce biosurfactants ( Dhanjal and Sharma, 2018 ; Guerra et al, 2018 ; Garg et al, 2021 ) and some of these biosurfactants have shown potential in bioremediation of pesticides ( Kennedy et al, 2011 ; Ghosh and Das, 2018 ). These microbes include Azotobacter chroococcum, Cobelia species, Myroides species, Nocardiopsis alba MSA10, Alcanivorax species, Micrococcus luteus, Yarrowia lipolytica .…”

“…These microbes include Azotobacter chroococcum, Cobelia species, Myroides species, Nocardiopsis alba MSA10, Alcanivorax species, Micrococcus luteus, Yarrowia lipolytica . There is a variety of screening approaches for detecting biosurfactant-producing microbes (as discussed in section “Methods for Detection of Microbial Biosurfactants”), some of which could be used for high-throughput (HTP) metagenomic library screening ( Domingos et al, 2015 ; Dhanjal and Sharma, 2018 ; Guerra et al, 2018 ). Thus, in screening, it is likely that novel gene clusters involved in biosurfactant production from soil and aquatic microbial assemblages will be discovered, speeding up the development of bioremediation technologies involving biosurfactants in pesticide-contaminated environments ( Hemmat-Jou et al, 2018 ; Taş et al, 2021 ).…”

Tapping the Role of Microbial Biosurfactants in Pesticide Remediation: An Eco-Friendly Approach for Environmental Sustainability

Pesticides are used indiscriminately all over the world to protect crops from pests and pathogens. If they are used in excess, they contaminate the soil and water bodies and negatively affect human health and the environment. However, bioremediation is the most viable option to deal with these pollutants, but it has certain limitations. Therefore, harnessing the role of microbial biosurfactants in pesticide remediation is a promising approach. Biosurfactants are the amphiphilic compounds that can help to increase the bioavailability of pesticides, and speeds up the bioremediation process. Biosurfactants lower the surface area and interfacial tension of immiscible fluids and boost the solubility and sorption of hydrophobic pesticide contaminants. They have the property of biodegradability, low toxicity, high selectivity, and broad action spectrum under extreme pH, temperature, and salinity conditions, as well as a low critical micelle concentration (CMC). All these factors can augment the process of pesticide remediation. Application of metagenomic and in-silico tools would help by rapidly characterizing pesticide degrading microorganisms at a taxonomic and functional level. A comprehensive review of the literature shows that the role of biosurfactants in the biological remediation of pesticides has received limited attention. Therefore, this article is intended to provide a detailed overview of the role of various biosurfactants in improving pesticide remediation as well as different methods used for the detection of microbial biosurfactants. Additionally, this article covers the role of advanced metagenomics tools in characterizing the biosurfactant producing pesticide degrading microbes from different environments.

“…It also aids in distinguishing various microorganisms in the environment, which are both complex and diverse. Other functional compounds, such as antibiotics (e.g., terragine) and microbial enzymes (e.g., amylases, lipases, and cellulases), may be produced from functional metagenomic libraries ( Dhanjal et al, 2018 ). Therefore, to accurately characterize the microbiological sample and its equivalents, enhanced detection techniques and high-throughput screening are required.…”
