“…------------------------------------g-1 of dry soil ------------------------------------------ The data obtained have demonstrated that solid or liquid forms of Si can significantly enhance plant growth and soil microbial activity in unpolluted and oil-polluted soils. Considering a key role of soil microbial population in the oil and oil product degradation, the Si application could accelerate the remediation of contaminated soil [26].…”

Numerous investigations demonstrate that active forms of silicon (Si) enhance the plant tolerance against abiotic stresses by several mechanisms, including increasing the antioxidant activities and minimizing oxidative damage. Soil contamination with oil and oil products relates to abiotic stress that detrimentally affects soil microbial population and plant growth. Considering the crucial role of microorganisms and plants in bioremediation of oil-polluted areas, Si substances can be beneficial to acceleration of soil reclamation. In greenhouse experiment, wheat was grown in Grey Forest Soil contaminated with used motor oil. The effect of fumed silica and monosilicic acid on soil enzymatic activity and plant growth was studied. Both Si substances provided increasing the plant biomass and the activities of catalase and dehydrogenase. As regards the plant growth, the effect of Si was more pronounced in polluted soil, while the enzyme activity was higher affected in unpolluted soil. The activities of catalase and dehydrogenase were closely correlated to the water-soluble Si in soil (R=0.91-0.92). Silicon substances with high content of, plant-and microorganism-available Si might be promising for involvement in bioremediation technology for oil-contaminated soil.

“…These compounds that to be metabolized and degraded should include those of non-biodegradable in addition to biodegradable pollutants. Although the advantages of microbial remediation include minimal secondary pollution and preservation of topsoil quality [3], the usefulness in treating a broad range of environmental contaminants is questionable. [4] focused on phytoremedial plants that are able to deal with this type of complex pollution.…”

“…The use of bioremediation by using microorganisms have been found many in the literature [2][3][4][5][6][7]. Microbial remediation can be simply defined by employing microorganisms to lower the bioavailability of pollutants (especially organic contaminants) so as to make less toxic to the ecosystem.…”

“…Anthropogenic environmental pollution is the introduction of contaminants (including xenobiotic compounds) into the natural environment as a result of human activity . Microbial environmental remediation in the conventional sense implies the use of microorganisms in degradation, detoxification and ultimately, removal of xenobiotic compounds from the environment . Similarly, environmental remediation by electro‐active microorganisms can be described as microbes utilizing EET to conduct (or EET that may result in) degradation and detoxification of environmental pollutants.…”

“…Myriad different environmental pollutants contained in soil, surface water or groundwater can be treated by microorganisms. Environmental decontamination of pollutants by microorganisms follow many biochemical pathways and the mechanisms of degradation and detoxification of various classes of environmental pollutants are extensively discussed in other reviews . Similarly, EET mechanisms aid microbes to perform degradation of various pollutants as well as corrosion of metal‐containing waste material.…”

Remediation of anthropogenic pollutants in our environment has become an imperative of the 21st century in order to sustain human activity and all life on the planet. With the current limitations of the existing technologies for this purpose, the need for innovative bioremediation technologies has become vitally important. Hitherto, electrochemically active microorganisms have only been a scientific curiosity and a platform for sustainable power production from waste material. However, recent research utilizing these electrochemically active microorganisms in bioelectrochemical systems (BES) has revealed their promising potential for bioremediation applications. The primary research focus of BES applications up-to now has been to optimize and increase their power output. The possibility of utilizing these systems for bioremediation applications has been a new facet of this field of work. This review provides a comprehensive outlook on the utilization of BES based technologies for remediation of xenobiotic environmental pollutants.
