 Aromatolium SP-CIB has been identified as a promising candidate for the bioremediation of polluted environments contaminated with metalloid compounds such as tellurite and selenite. This bacterium can efficiently degrade these compounds into elemental forms of tellurium and selenium, respectively, resulting in the formation of rod-shaped tellurium nanoparticles and spherical selenium nanoparticles. Additionally, the presence of a specific gene encoding a methyl-transferase enzyme in the aromatolium SP. CIB genome allows for the rapid degradation of these compounds, further accelerating the process of bioremediation.
