TL;DR: Li et al. as discussed by the authors investigated the effects of different concentrations of heavy metals on the composition of bacterial communities in coal gangue sites, and found that Actinobacteriota, Proteobacteria, Chloroflexi, Acidobacteria and Gemmatimonadota were the bacterial taxa most resistant to heavy metal stress at gangue site.

TL;DR: In this article , 12 native bacteria previously isolated in soils of cocoa farms located in the western Colombian Andes (Santander), and tolerant to 2500 µM CdCl2 (120 mg Cd/L), were chosen in order to test their tolerance and Cd immobilization using liquid culture medium (Nutritive broth) at different concentrations of heavy metals.
Abstract: Twelve cadmium native bacteria previously isolated in soils of cocoa farms located in the western Colombian Andes (Santander), and tolerant to 2500 µM CdCl2 (120 mg Cd/L), were chosen in order to test their tolerance and Cd immobilization using liquid culture medium (Nutritive broth) at different concentrations of heavy metals. Furthermore, in the greenhouse experiments, the strains Exiguobacterium sp. (11-4A), Klebsiella variicola sp. (18-4B), and Enterobacter sp. (29-4B) were applied in combined treatments using CCN51 cacao genotype seeds grown in soil with different concentrations of Cd. All bacterial strains’ cell morphologies were deformed in TEM pictures, which also identified six strain interactions with biosorption and four strain capacities for bioaccumulation; FT-IR suggested that the amide, carbonyl, hydroxyl, ethyl, and phosphate groups on the bacteria biomass were the main Cd binding sites. In the pot experiments, the concentration of Cd was distributed throughout the cacao plant, but certain degrees of immobilization of Cd can occur in soil to prevent an increase in this level in roots with the presence of Klebsiella sp.

TL;DR: In this article , the combined effects of Cd, Pb, Zn, Hg and regulation mechanisms in Solanum nigrum L. were investigated, and they provided a theoretical basis and guidance for S.nigrum l. as a phytoremediation plant under combined heavy metal pollution.

TL;DR: In this article , the authors investigated the response of Tamarix ramosissima, a phylloplane bacterial community to heavy metal, and the effect of the process on host growth in situ.
