“…Actually, the combination of biostimulation and rhizoremediation led to the highest NUS and H' values (Table4). These highest values were observed in SMS Festuca treatment Rathankumar et al (2020). emphasized that SMS, together with the originally inoculated fungus, contains a diverse microbial community, which can result in higher values of microbial functional diversity.…”

The biological remediation of mixed contaminated soils is exceedingly challenging as it often requires actions to minimize metal-induced risks while degrading organic contaminants. In this study, we assessed the effectiveness of three biological remediation options (rhizoremediation, biostimulation, mycoremediation), applied together or separately, for the recovery of a mixed contaminated soil from a gravel pit. We evaluated the effectiveness of these remediation strategies in terms of both reduction in soil contamination levels and recovery of soil health. The combination of biostimulation (by the application of composted sewage sludge) and rhizoremediation with Medicago sativa plants resulted in the highest recovery of soil health. The application of the composted sewage sludge led to the highest reduction in anthracene and polychlorinated biphenyls concentrations. Still, the studied biological remediation options did not manage to decrease soil contamination levels below some of the limits set by the regional legislation. By contrasts, they enhanced soil health, as reflected by the values of soil microbial indicators, pointing out to the fact that they can stimulate soil functioning in a relatively short period of time, long before the concentration of soil contaminants is significantly reduced.

“…Penicillium (Rathankumar et al, 2022). The initial step of PAH oxidation by non-ligninolytic fungi is an intracellular cytochrome P450 monooxygenase enzyme (CYP450)-stimulated reaction that forms arene oxide and water (Rathankumar et al, 2020). PAHs adsorbed by the fungal mycelium system are oxidized by the incorporation of a single oxygen molecule and transformed into unstable arene oxide, which is either non-enzymatically transformed into a phenol derivative or hydrated by epoxide hydrolase into transdihydrodiols (Dickson et al, 2019).…”

Petroleum hydrocarbons (PHCs) are key energy sources for several industries and daily life. Soil contamination from oily PHC spills is commonly detected in cities and industrial facilities where crude oil is used. The release of PHC pollutants into the environment, whether accidentally from petroleum industries or human activities, has become a leading source of soil pollution. Consequently, the mineralization of PHC-polluted sites has become a central issue worldwide. Although bioremediation is imperative for environmental safety and management, several approaches have been developed for PHC bioremediation. However, much remains to be explored in this regard. This review explores bioremediation of PHC-contaminated soil and provides a comprehensive examination of the principles, degradation mechanisms, and recent advancements in the field. Several microbial species have been used to study the bioremediation of PHCs, emphasizing the pivotal roles of diverse microbial communities. Aspergillus spp., Proteobacteria, and Firmicutes groups of microorganisms were the most efficient in remediating PHC-contaminated soil. The fundamental concepts behind the bioremediation of PHC and the complex mechanisms that govern degradation were elucidated. Limiting factors in the bioremediation process and recent innovations propelling the field were also discussed. Therefore, understanding the degradation pathway, ensuring complete degradation of contaminants, and flexible legislation for the proper use of genetically engineered microbes can make bioremediation more sustainable and cost-effective.

“…Currently, bio-adsorbents are an ecological, effective, and low-cost option, with potential candidates for use as bio-adsorbents including fungi, algae, bacteria, and agricultural waste. The fungi Pleurotus ostreatus, Phanerochaete chrysosporium, Lentinus edodes, Trametes versicolor, and Ganoderma lucidum have been reported to be highly effective in eliminating aromatic chlorinated phenolic compounds and polycyclic aromatic hydrocarbons (PAHs), present in water or soil (Rathankumar et al, 2020;Košnář et al, 2019;Nguyen et al, 2014;Farkas et al, 2013). One study explored the elimination of phenol and 2-chlorophenol from an aqueous solution using pellets, both live and heat-inactivated of Funalia trogii, finding that the efficiency of phenol elimination increased significantly in line with an increased quantity of biomass.…”

The environment pollution or contamination is a serious problem, a great deal of research is being undertaken to combat contaminants such as xenobiotic and recalcitrant compounds, particularly heavy metals, dyes,phenolic compounds and other recalcitrant pollutants produced by a wide range of industrial activities. These compounds have an adverse impact on the environment, particularly when generated by industrial processes and then disposed off without adequate treatment. Mycoremediation is defined as the use of fungi for bioremediation, especially degradation or retention of contaminants. Biosorption and bioaccumulation are two of the mechanisms by which fungi remove contaminants through mycelium. In many cases, these processes involve metabolization and even mineralization of these contaminants, corresponding to a biological contaminant removal system with great potential for use in bioremediation processes. The present review describes the unique characteristics of fungal mycelium that make it a biomaterial with potential applications in various fields of biotechnology, specifically evaluating its biosorption/bioaccumulation properties and potential application for the bioremediation of different water-borne contaminants. This review focus on the researches conducted on the bioremediation of inorganic and organic pollutants, the mechanisms involved in the process, and the main environmental factors affecting it. Moreover, kinetics and equilibrium modeling of the removal efficiency achieved via biosorption/bioaccumulation is analyzed in order to better understand these processes and overcome some of the technical barriers to their large-scale application in the mycoremediation of wastewater. Key words: Bioaccumulation, Biosorption, Fungi, Mycoremediation, Xenobiotics
