The Role of Plant Growth Promoting Bacteria on Mercury Remediation

Phytobial remediation is a cutting-edge technique that reduces mercury (Hg) poisoning of the environment by utilising plants and bacteria. Plant growth-promoting bacteria (PGPB) that aids phytoremediation have recently received a lot of attention for their ability to increase plant growth and metal tolerance while removing Hg on a massive scale. This chapter focuses on the PGPB traits that affect plants and the ways in which they respond to challenges brought on by Hg. We will cover a number of current instances of systems that increase the availability of Hg to plants and help them deal with Hg stressors. Despite the fact that phytoremediation has been shown to have limitations, encouraging outcomes have been achieved with consistent monitoring. An evaluation of the environmental consequences of PGPB is necessary before introducing PGPB-assisted phytoremediation of Hg in a field, especially with regard to the implications on indigenous bacteria.
