“…Conversely, rapid responders, by virtue of their relatively higher ribosomal content before wet-up seem to resuscitate almost immediately. Many of the taxa that increased their relative abundance (as DNA) within the 72-h experiment were classified as delayed responders, among them members of the Sphingomonadales and Xanthamonadales, representatives of which were recently shown to incorporate 18 O water into their DNA within 48 h of wet-up (34). It is possible, however, that other taxa may have grown earlier and then been displaced, in a pattern that we did not detect.…”

The pulse of carbon dioxide (CO 2 ) resulting from the first rainfall after the dry summer in Mediterranean ecosystems is so large that it is well documented at the landscape scale, with the CO 2 released in a few days comparable in magnitude to the annual net carbon exchange of many terrestrial ecosystems. Although the origin of this CO 2 is debated, we show that the pulse of CO 2 is produced by a three-step resuscitation of the indigenous microbial community. Specific phylogenetic groups of microorganisms activate and contribute to the CO 2 pulse at different times after a simulation of the first rainfall following the severe summer drought. Differential resuscitation was evident within 1 h of wet-up, with three primary response strategies apparent according to patterns of relative ribosomal quantity. Most bacteria could be classified as rapid responders (within 1 h of wet-up), intermediate responders (between 3 and 24 h after wet-up), or delayed responders (24–72 h after wet-up). Relative ribosomal quantities of rapid responders were as high in the prewet dry soils as at any other time, suggesting that specific groups of organisms may be poised to respond to the wet-up event, in that they preserve their capacity to synthesize proteins rapidly. Microbial response patterns displayed phylogenetic clustering and were primarily conserved at the subphylum level, suggesting that resuscitation strategies after wet-up of dry soil may be a phylogenetically conserved ecological trait.

“…Many microbes produce cyst-like cells that are smaller and restructured from vegetative cells (18), whereas Firmicutes and some Actinobacteria produce spores. Although cysts and spores are generally considered dormant states, other physiological responses may also provide a degree of protection from some types of stress.…”

“…Microbial biomass is the most important parameter used to characterize biological soil processes, because it is 'a primary catalyst of biogeochemical processes as well as an energy and nutrient reservoir' (Kutsch et al, 2010). It has been used, although to a much lesser extent, as a measure for the carbon turnover potential of soils, and as microbes have a high tolerance towards stress conditions (as found in mine impacted soils) they are well equipped to survive and remain active enhancing recovery, unless that is the stress is so great that it is lethal or forces dormancy (Farrar and Reboli, 1999;Suzina et al, 2004). Microbial biomass, while a small portion of SOC, mediates the transfer of SOC among inputs, low fraction organic carbon and organo-mineral high fraction organic carbon.…”

a b s t r a c tThe impact of mine spoil on the landscape is significant, as excavated rock-debris is commonly disposed in heaps that blanket the original land surface. Spoil heaps destroy the original soil habitat releasing soilbound carbon, which is difficult to re-estate when mining operations cease and restoration begins. The present work follows the development of vegetative cover on a coalmine spoil tip in India over a period of 19 years following restoration. The potential of re-vegetated the mine spoil to imbibe carbon is examined through the development of above-and below-ground biomass development. It was observed that the soil organic carbon and microbial biomass carbon (MBC) significantly increased with re-vegetation age, with above ground biomass increasing by 23 times, and belowground biomass increased by 26 times during the period of study. Soil organic carbon and MBC increased by 4× and 6.6× times, respectively. The average calculated annual carbon budget was 8.40 T/ha/year, of which 2.14 T/ha was allocated to above ground biomass, 0.31 T/ha to belowground biomass, 2.88 T/ha to litter mass and 1.35 T/ha was sequestered into the soil. This work has shown that the development of biomass following the restoration of mine spoil was significant and that considerable quantities of carbon were stored in above and below ground plant matter, and in the soil itself. It is concluded that appropriate restoration strategies can be used to rapidly establish a viable, healthy and sustainable ecosystem that imbibes carbon into former mine-impacted land.

“…Only specific microorganisms subsist at these elevated temperatures and high salinity due to modifications in proteins, DNA, and cell membrane composition as well as intracellular accumulation of low molecular compounds (Aerts et al 1985;Kempf and Bremer 1998;Kumar and Nussinov 2001;Roberts 2005). Moreover, some microorganisms are able to get into a dormancy stage by forming spores, cysts or other types of resting cells and survive starvation, exposure to extreme temperatures, and elevated background radiation (Burke and Wiley 1937;Amy 1997;Suzina et al 2004;Johnson et al 2007). The exploitation of sedimentary geologic formations in the North German Basin (NGB) has provided suitable conditions for temporary aquifer heat and cold storage (ATES aquifer thermal energy storage) (Schmidt et al 2004).…”

Thermal effects on microbial composition and microbiologically induced corrosion and mineral precipitation affecting operation of a geothermal plant in a deep saline aquifer

et al. 2013

The microbial diversity of a deep saline aquifer used for geothermal heat storage in the North German Basin was investigated. Genetic fingerprinting analyses revealed distinct microbial communities in fluids produced from the cold and warm side of the aquifer. Direct cell counting and quantification of 16S rRNA genes and dissimilatory sulfite reductase (dsrA) genes by real-time PCR proved different population sizes in fluids, showing higher abundance of bacteria and sulfate reducing bacteria (SRB) in cold fluids compared with warm fluids. The operation-dependent temperature increase at the warm well probably enhanced organic matter availability, favoring the growth of fermentative bacteria and SRB in the topside facility after the reduction of fluid temperature. In the cold well, SRB predominated and probably accounted for corrosion damage to the submersible well pump, and iron sulfide precipitates in the near wellbore area and topside facility filters. This corresponded to lower sulfate content in fluids produced from the cold well as well as higher content of hydrogen gas that was probably released from corrosion, and maybe favored growth of hydrogenotrophic SRB. This study reflects the high influence of microbial populations for geothermal plant operation, because microbiologically induced precipitative and corrosive processes adversely affect plant reliability.2
