“…Relative abundance of phylotypes similar to the phylum OD1, commonly found in anoxic groundwater environments increased in the treatment zone and remained high downgradient. The well EKMW02 also included phylotypes similar to the orders Thiobacterales (9.48%) and Micrarchaeles (8.24%), previously identified in sediments and thermophilic environments (Paul et al 2016;Chen et al 2018). The sample downgradient of the treatment zone (EKMW10) was dominated by phylotypes most similar to microbes often found in dechlorinating cultures.…”

There is an increased interest in finding remedies for contamination in low permeability and advection-limited aquifers. A technology applicable at these sites, electrokinetic-enhanced bioremediation (EK-BIO), combines traditional bioremediation and electrokinetic technologies by applying direct current to transport bioremediation amendments and microbes in situ. The effect of this technology on the native soil microbial community has only been previously investigated at the bench scale. This research explored the influence of EK-BIO on subsurface microbial communities at a field-scale demonstration site. The results showed that, similar to the findings in laboratory studies, alpha diversity decreased and beta diversity differed temporally, based on treatment phase. Enrichments in specific taxa were linked to the bioaugmentation culture and electron donor. Overall, findings from our study, one of the first field-scale investigations of the influence of electrokinetic bioremediation on subsurface microbial communities, are very similar to bench-scale studies on the topic, suggesting good correlation between laboratory and field experiments on EK-BIO and showing that lessons learned at the benchtop are important and relevant to field-scale implementation. Key points• Microbial community analysis of field samples validates laboratory study results • Bioaugmentation cultures and electron donors have largest effect on microbial community

“…Consequently, the common ancestor of Alicyclobacillus was more likely to have an early separation event for AMD environment adaptation. Moreover, with an increasing number of environment stresses, such as pH, temperature, and heavy metal concentration, the abundance of the Alicyclobacillus genus decreases across natural soil (21.1%–62.3%) (Yang et al ., 2014; Yang et al ., 2016), hot spring (1.9%–30.3%) (Paul et al ., 2016; Rincón‐Molina et al ., 2018), and AMD (0.61%–15%) (Brantner et al ., 2014; Chen et al ., 2014). These ecological investigations revealed that Alicyclobacillus species were confronted with more intense survival pressures in AMD than other environments.…”

Alicyclobacillus species inhabit diverse environments and have adapted to broad ranges of pH and temperature. However, their adaptive evolutions remain elusive, especially regarding the role of mobile genetic elements (MGEs). Here, we characterized the distributions and functions of MGEs in Alicyclobacillus species across five environments, including acid mine drainage (AMD), beverages, hot springs, sediments, and soils. Nine Alicyclobacillus strains were isolated from AMD and possessed larger genome sizes and more genes than those from other environments. Four AMD strains evolved to be mixotrophic and fell into distinctive clusters in phylogenetic tree. Four types of MGEs including genomic island (GI), insertion sequence (IS), prophage, and integrative and conjugative element (ICE) were widely distributed in Alicyclobacillus species. Further, AMD strains did not possess CRISPR-Cas systems, but had more GI, IS, and ICE, as well as more MGE-associated genes involved in the oxidation of iron and sulfide and the resistance of heavy metal and low temperature. These findings highlight the differences in phenotypes and genotypes between strains isolated from AMD and other environments and the important role of MGEs in rapid environment niche expansions.

“…In the eastern countries, other geothermal aquifers have been studied: Trans-Himalayan plateau [56], Pakistan [57,58], Tibet [59], China [60], India [61], Thailand [62], and Japan [63,64]. In the Latin-American countries, the most studied are Copahue in Argentina [65] and other thermal springs in Mexico, Perú, Colombia, and the Caribbean Island of Montserrat [66][67][68][69], and also, on the African continent, in Tunisia [70] and South Africa [71]. Some examples are described below.…”

Hydrobiome of Thermal Waters: Potential Use in Dermocosmetics

2023

View full text Add to dashboard Cite

Over the course of the last 20 years, numerous studies have identified the benefits of thermal waters on different skin conditions. Consequently, several investigations have been carried out on their effects on the skin, which are linked to their chemical composition, and, recently, scientists have turned their attention to the role of the thermal spring’s microbiota, named “hydrobiome”, regarding these therapeutic effects. At the same time, the development of cosmetics based on pre, pro, and postbiotics has reached great relevance and research is increasing every day. This review gathers information on the biological diversity of thermal spring waters and their potential use in obtaining biological compounds, metabolites, or bacterial extracts for use in dermocosmetics as active ingredients. These bioactive compounds are able to improve dermatological diseases such as atopic dermatitis or rosacea and ameliorate pruritus and xerosis; moreover, they can increase protection against UV exposure, strengthen barrier function, maintain good homeostasis of skin defenses, repair damaged skin, promote wound healing, improve skin condition, reduce uneven skin pigmentation, and prevent skin aging. From a future perspective, fruitful cooperation among researchers, hydrologists, thermal spa centers, and cosmetic industries will drive this sector toward a better understanding of the role of the hydrobiome of thermal spring waters on healthy skin and dermatological diseases and consider the inclusion of derivatives of this hydrobiome (in the form of fermenters, lysates, extracts, etc.) in dermocosmetic formulations. Therefore, and being aware of the potential of the hydrobiome in dermatological and skin care applications, the future prospects for the use of bioactive substances derived from it in dermocosmetic formulations are promising.
