Abstract
Copper (Cu) is important for plant growth, but high concentrations can lead to detrimental effects such as primary root length inhibition, vegetative tissue chlorosis, and even plant death. The interaction between plant-soil microbiota and roots can potentially affect metal mobility and availability, and, therefore, overall plant metal concentration. Cupriavidus metallidurans CH34 is a multi metal-resistant bacterial model that alters metal mobility and bioavailability through ion pumping, metal complexation, and reduction processes. The interactions between strain CH34 and plants may affect the growth, metal uptake, and translocation of Arabidopsis thaliana plants that are exposed to or not exposed to Cu. In this study, we looked also at the specific gene expression changes in C. metallidurans when co-cultured with Cu-exposed A. thaliana. We found that A. thaliana’s rosette area, primary and secondary root growth, and dry weight were affected by strain CH34, and that beneficial or detrimental effects depended on Cu concentration. An increase in some plant growth parameters was observed at copper concentrations lower than 50 µM and significant detrimental effects were found at concentrations higher than 50 µM Cu. We also observed up to a 90% increase and 60% decrease in metal accumulation and mobilization in inoculated A. thaliana. In turn, copper-stressed A. thaliana altered C. metallidurans colonization, and cop genes that encoded copper resistance in strain CH34 were induced by the combination of A. thaliana and Cu. These results reveal the complexity of the plant-bacteria-metal triad and will contribute to our understanding of their applications in plant growth promotion, protection, and phytoremediation strategies.

Abstract
Cupriavidus metallidurans, and in particular type strain CH34, became a model bacterium to study bacterial resistance to metals. Although nowadays the routine use of a wide variety of omics and molecular techniques allow refining, deepening and expanding our knowledge on adaptation and resistance to metals, these were not available at the onset of C. metallidurans research starting from its isolation in 1976. This minireview describes the early research and legacy tools used to study its metal resistance determinants, characteristic megaplasmids, ecological niches and environmental applications.

Abstract
The main aim of this work was to characterize the microbial community structure and resistance gene (CzcA) shifts in up-flow constructed wetlands-microbial fuel cell (CW-MFC) treating Zn (II) contaminated wastewater. Two CW-MFC devices were operated, i.e. the experimental group (EG) treating Zn (II) wastewater, and the control group (CG) treating Zn (II)-free wastewater. The results showed the CW-MFC combination exhibited good removal efficiency on Zn (II), while the average voltage, the power density and the removal rates (TP, TN, NH4+-N and COD) significantly reduced (p < 0.05). The microbial community structure showed that the Zn (II) significantly reduced the abundance of some functional genus (p < 0.05), such as Ochrobactrum, Nitrosomonas, Pseudomonas and Dechloromonas. Zn (II) inhibited the microbial richness in the anode, but it played a positive role in the cathode. Anew, the expression of the CzcA in the CW-MFC was promoted by Zn (II), particularly in the cathode.

Abstract
Analysis of the complete nucleotide sequence of plasmid pM7012 from 2,4-dichlorophenoxyacetic-acid (2,4-D)-degrading bacterium Burkholderia sp. M701 revealed that the plasmid had 582 142 bp, with 541 putative protein-coding sequences and 39 putative tRNA genes for the transport of the standard 20 aa. pM7012 contains sequences homologous to the regions involved in conjugal transfer and plasmid maintenance found in plasmids byi_2p from Burkholderia sp. YI23 and pBVIE01 from Burkholderia sp. G4. No relaxase gene was found in any of these plasmids, although genes for a type IV secretion system and type IV coupling proteins were identified. Plasmids with no relaxase gene have been classified as non-mobile plasmids. However, nucleotide sequences with a high level of similarity to the genes for plasmid transfer, plasmid maintenance, 2,4-D degradation and arsenic resistance contained on pM7012 were also detected in eight other megaplasmids (~600 or 900 kb) found in seven Burkholderia strains and a strain of Cupriavidus, which were isolated as 2,4-D-degrading bacteria in Japan and the United States. These results suggested that the 2,4-D degradation megaplasmids related to pM7012 are mobile and distributed across various bacterial species worldwide, and that the plasmid group could be distinguished from known mobile plasmid groups.

Abstract
In this study, samples from the spacecraft assembly clean room BAF (final assembly building), located at Centre Spatial Guyanais in Kourou, French Guiana, were characterized by qualitative and quantitative methods to determine the bioburden and biodiversity. The cultivation assays mainly focused on extremotolerant microorganisms that have special metabolic skills, such as the ability to grow without oxygen, fix nitrogen, grow autotrophically, or reduce sulfate. A broad range of media and growth conditions were used to simulate possible extraterrestrial environments and clean room buildings. In addition to these alternative cultivation assays, the ESA standard protocol for bioburden estimation was also applied. The phylogenetic analysis of the isolates (mainly facultative anaerobes) showed an extraordinarily broad cultivable biodiversity. Overall, 49 species were isolated and identified as members of the bacterial phyla Actinobacteria, Firmicutes, α-, β-, γ-Proteobacteria, and Bacteroidetes/Chlorobi. In addition to cultivation-based analyses, molecular techniques were also applied, including construction of a 16S rRNA gene clone library. The results indicate a wide-ranging microbial diversity (12 bacterial phyla, 34 families) that not only confirms the results of the cultivation efforts but also deepens our understanding of the noncultivable variety. Our investigations hint at a very broad, mainly uncultivated microbial diversity.

Abstract
Four Cupriavidus metallidurans and eight Ralstonia pickettii isolates from the space industry and the International Space Station (ISS) were characterized in detail. Nine of the 12 isolates were able to form a biofilm on plastics and all were resistant to several antibiotics. R. pickettii isolates from the surface of the Mars Orbiter prior to flight were 2.5 times more resistant to UV-C(254nm) radiation compared to the R. pickettii type strain. All isolates showed moderate to high tolerance against at least seven different metal ions. They were tolerant to medium to high silver concentrations (0.5-4 μM), which are higher than the ionic silver disinfectant concentrations measured regularly in the drinking water aboard the ISS. Furthermore, all isolates survived a 23-month exposure to 2 μM AgNO(3) in drinking water. These resistance properties are putatively encoded by their endogenous megaplasmids. This study demonstrated that extreme resistance is not required to withstand the disinfection and sterilization procedures implemented in the ISS and space industry. All isolates acquired moderate to high tolerance against several stressors and can grow in oligotrophic conditions, enabling them to persist in these environments.
