“…Furthermore, the presence of phosphate in the soil groundwater could shift bacterial resistance mechanisms more towards intra-and/or extracellular phosphate mediated complexation resulting in the precipitation and immobilization of metals and radionuclides. Although phosphate mediated complexation has been shown for Cd 2+ , Zn 2+ and several other metals and radionuclides (Basnakova et al, 1998;Andrade et al, 2004;Renninger et al, 2004;Zeng et al, 2020), the best known Ni 2+ resistance mechanism is efflux-mediated resistance (López-Maury et al, 2002;Nies, 2003;Mergeay and Van Houdt, 2015). Nevertheless, our experimental setup did not allow to interpret the individual effect of total phosphor or phosphate on the microbial community and thus no clear impact was observed.…”

Microbial communities are essential for a healthy soil ecosystem. Metals and radionuclides can exert a persistent pressure on the soil microbial community. However, little is known on the effect of long-term cocontamination of metals and radionuclides on the microbial community structure and functionality. We investigated the impact of historical discharges of the phosphate and nuclear industry on the microbial community in the Grote Nete river basin in Belgium. Eight locations were sampled along a transect to the river edge and one location further in the field. Chemical analysis demonstrated a metal and radionuclide contamination gradient and revealed a distinct clustering of the locations based on all metadata. Moreover, a relation between the chemical parameters and the bacterial community structure was demonstrated. Although no difference in biomass was observed between locations, cultivation-dependent experiments showed that communities from contaminated locations survived better on singular metals than communities from control locations. Furthermore, nitrification, a key soil ecosystem process seemed affected in contaminated locations when combining metadata with microbial profiling. These results indicate that long-term metal and radionuclide pollution impacts the microbial community structure and functionality and provides important fundamental insights into microbial community dynamics in co-metalradionuclide contaminated sites.

Cave environments on Earth have long provided shelter to a variety of organisms, from microbes to humans. Though their scales of interest differ vastly, these two examples have sought the same comfort from caves: a stable and sheltered environment, protected from the woes of the surface world. Since the discovery of lava caves on Mars (see Sauro et al., 2020 for a review), they have become of renewed interest as targets for human shelter in future missions, as well as areas of astrobiological interest, with the potential of harboring traces of extant or extinct extraterrestrial life.
