“…The use of microbial bioremediation for the cleanup of mercury contaminated water was first demonstrated by Williams and Silver (1984), who assessed bacterial resistance and detoxification of heavy metals (Ustiatik et al, 2022). Since then, the application of this process has been made easier by the transgenic approach (Saravanan et al, 2022).…”

“…Microbial bioremediation is an effective alternative to traditional remediation processes because it is sustainable, eco-friendly, costeffective, reduces the chances of producing secondary pollutants and requires less energy than chemical methods (Hou et al, 2023). Moreover, it can be useful to the polluted area itself and has great potential for pollutant removal (Ustiatik et al, 2022). Table 1 lists microbes used in bioremediation of Hg.…”

Mercury (Hg) pollution of soil and water environments is a major global threat to human health, agri‐food systems and ecosystems and industrial activities mainly coal combustion augmented their content in different environmental media. Bioremediation is a nature‐based solution involving microbial‐ and plant‐based (phytoremediation) technologies that clean‐up Hg contaminated sites. Here, we review Hg‐resistant bacteria and how latest insights in our understanding of the cellular and biochemical mechanisms of the mer operon genes responsible for Hg resistance and transformation have facilitated developments in microbial Hg‐bioremediation. We also review the phytoremediation mechanisms, including those of bacterial‐ and fungi‐assisted phytoremediation processes, which have shown promising results in reducing Hg2+ to Hg0. This review provides a detailed knowledge of novel Hg bioremediation mechanisms and methods. Consequently, microbial‐ and phyto‐based bioremediation technologies have a critical role in the reclamation of Hg‐contaminated environments and the protection of human health and ecosystems.

Plants defend themselves against ecological stresses including drought. Therefore, they adopt various strategies to cope with stress, such as seepage and drought tolerance mechanisms, which allow plant development under drought conditions. There is evidence that microbes play a role in plant drought tolerance. In this study, we presented a review of the literature describing the initiation of drought tolerance mediated by plant inoculation with fungi, bacteria, viruses, and several bacterial elements, as well as the plant transduction pathways identified via archetypal functional or morphological annotations and contemporary “omics” technologies. Overall, microbial associations play a potential role in mediating plant protection responses to drought, which is an important factor for agricultural manufacturing systems that are affected by fluctuating climate.
