“…Several genomes of eurypsychrophilic acidophilic bacteria have been published ( Table 1 ) including seven At. ferrivorans strains, namely, SS3 (Liljeqvist et al, 2011b ), CF27 (Talla et al, 2013 ), PQ33 (Ccorahua-Santo et al, 2017 ), YL15 (Peng et al, 2017 ), ACH (Barahona et al, 2020 ), NO-37 (Moya-Beltrán et al, 2021 ), and XJFY6S-08 (Zhao et al, 2021 ). The At.…”

Eurypsychrophilic acidophiles: From (meta)genomes to low-temperature biotechnologies

et al. 2023

Low temperature and acidic environments encompass natural milieus such as acid rock drainage in Antarctica and anthropogenic sites including drained sulfidic sediments in Scandinavia. The microorganisms inhabiting these environments include polyextremophiles that are both extreme acidophiles (defined as having an optimum growth pH < 3), and eurypsychrophiles that grow at low temperatures down to approximately 4°C but have an optimum temperature for growth above 15°C. Eurypsychrophilic acidophiles have important roles in natural biogeochemical cycling on earth and potentially on other planetary bodies and moons along with biotechnological applications in, for instance, low-temperature metal dissolution from metal sulfides. Five low-temperature acidophiles are characterized, namely, Acidithiobacillus ferriphilus, Acidithiobacillus ferrivorans, Acidithiobacillus ferrooxidans, “Ferrovum myxofaciens,” and Alicyclobacillus disulfidooxidans, and their characteristics are reviewed. Our understanding of characterized and environmental eurypsychrophilic acidophiles has been accelerated by the application of “omics” techniques that have aided in revealing adaptations to low pH and temperature that can be synergistic, while other adaptations are potentially antagonistic. The lack of known acidophiles that exclusively grow below 15°C may be due to the antagonistic nature of adaptations in this polyextremophile. In conclusion, this review summarizes the knowledge of eurypsychrophilic acidophiles and places the information in evolutionary, environmental, biotechnological, and exobiology perspectives.

“…Development of this trend in the area of bioleaching was initiated by studying the genomics of bioleaching microorganisms. This was accompanied by an accumulation of data over the past decades [ 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 , 100 ]. The present time seems to mark the beginning of new stage, namely the genetic selection of bacteria with desired properties.…”

The presented review is based on scientific microbiological articles and patents in the field of biomining valuable metals. The main attention is paid to publications of the last two decades, which illustrate some shifts in objects of interest and modern trends both in general and applied microbiology. The review demonstrates that microbial bioleaching continues to develop actively, despite various problems in its industrial application. The previous classic trends in the microbial bioleaching persist and remain unchanged, including (i) the search for and selection of new effective species and strains and (ii) technical optimization of the bioleaching process. Moreover, new trends were formed during the last decades with an emphasis on the phylogeny of leaching microbiota and on genomes of the leaching microorganisms. This area of genomics provides new, interesting information and forms a basis for the subsequent construction of new leaching strains. For example, this review mentions some changed strains with increased resistance to toxic compounds. Additionally, the review considers some problems of bioleaching valuable metals from toxic arsenopyrite.

“…Besides potassium transport, the strategy of these bio-mining microorganisms to adapt to osmotic pressure is mainly the synthesis of compatible solutes, such as betaines, ectoine, glucans, sucrose, glycine, and proline. At low temperature, cold adaptation mechanisms of A. ferrivorans XJFY6S-08 mainly included RNA metabolism, molecular chaperones and helicases, membrane modifications, compatible solutes, biofilm and extracellular polysaccharides [43]. These possible mechanisms in extreme environments can be inferred through genomics, but their sequence cannot be completely determined.…”

Bio-mining microorganisms are a key factor affecting the metal recovery rate of bio-leaching, which inevitably produces an extremely acidic environment. As a powerful tool for exploring the adaptive mechanisms of microorganisms in extreme environments, omics technologies can greatly aid our understanding of bio-mining microorganisms and their communities on the gene, mRNA, and protein levels. These omics technologies have their own advantages in exploring microbial diversity, adaptive evolution, changes in metabolic characteristics, and resistance mechanisms of single strains or their communities to extreme environments. These technologies can also be used to discover potential new genes, enzymes, metabolites, metabolic pathways, and species. In addition, integrated multi-omics analysis can link information at different biomolecular levels, thereby obtaining more accurate and complete global adaptation mechanisms of bio-mining microorganisms. This review introduces the current status and future trends in the application of omics technologies in the study of bio-mining microorganisms and their communities in extreme environments.
