Journal ArticleDOI
The relationships between heavy metals and bacterial communities in a coal gangue site.
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.
Journal ArticleDOI
Bacterial metal(loid) resistance genes (MRGs) and their variation and application in environment: A review.
TL;DR: In this article , a review of the historical evolution, resistance mechanisms, environmental variation, and environmental applications of bacterial metal-resistant genes (MRGs) is presented, and the potential hazards, unresolved problems, and future research directions are also discussed.
Journal ArticleDOI
Tolerance and Cadmium (Cd) Immobilization by Native Bacteria Isolated in Cocoa Soils with Increased Metal Content
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.
Journal ArticleDOI
Ecological toxicity of Cd, Pb, Zn, Hg and regulation mechanism in Solanum nigrum L.
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.
Journal ArticleDOI
Heavy metals reshaping the structure and function of phylloplane bacterial community of native plant Tamarix ramosissima from Pb/Cd/Cu/Zn smelting regions.
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.

Escherichia coli mechanisms of copper homeostasis in a changing environment
Christopher Rensing,Gregor Grass +1 more
TL;DR: Escherichia coli is equipped with multiple systems to ensure safe copper handling under varying environmental conditions, but pathways of copper uptake and intracellular copper handling are still not identified in E. coli.
Journal ArticleDOI
SlmA, a Nucleoid-Associated, FtsZ Binding Protein Required for Blocking Septal Ring Assembly over Chromosomes in E. coli
TL;DR: The combined genetic, cytological, and biochemical results suggest that SlmA is a DNA-associated division inhibitor that is directly involved in preventing Z ring assembly on portions of the membrane surrounding the nucleoid.

Thermotolerance Requires Refolding of Aggregated Proteins by Substrate Translocation through the Central Pore of ClpB
Jimena Weibezahn,Peter Tessarz,Christian Schlieker,Regina Zahn,Zeljka Maglica,Sukyeong Lee,Hanswalter Zentgraf,Eilika Weber-Ban,David A. Dougan,David A. Dougan,Francis T.F. Tsai,Axel Mogk,Bernd Bukau +12 more
TL;DR: The activity switch of BAP to a degrading disaggregase does not support thermotolerance development, demonstrating that cell survival during severe thermal stress requires reactivation of aggregated proteins.

Ralstonia metallidurans, a bacterium specifically adapted to toxic metals: towards a catalogue of metal-responsive genes
Max Mergeay,Sébastien Monchy,Tatiana Vallaeys,Vanessa Auquier,Abderrafi Benotmane,Philippe N. Bertin,Safiyh Taghavi,Safiyh Taghavi,John J. Dunn,Daniel van der Lelie,Daniel van der Lelie,Ruddy Wattiez +11 more
TL;DR: A first inventory of metal resistance genes and operons across R. metallidurans suggests that metal-resistant Ralstonia, through evolution, are particularly well adapted to the harsh environments typically created by extreme anthropogenic situations or biotopes.
Journal ArticleDOI
The structure of FtsZ filaments in vivo suggests a force-generating role in cell division.
TL;DR: In this paper, electron cryotomographic reconstructions of dividing Caulobacter crescentus cells where individual arc-like filaments were resolved just underneath the inner membrane at constriction sites were reported.
