“…Microbial solubilization and the breakdown of minerals can be caused by a wide range of microbial extracellular metabolites such as organic acids and exopolysaccharides, siderophores, which kombucha community-members produce, consuming carbohydrates. In natural settings, adapted consortia of indigenous microorganisms employ the bioleaching mechanisms to derive energy from organo-minerals (Włodarczyk et al 2015 );, our earlier and present results showed highly effective adaptation capacity of domesticated Bioleaching may cause a toxicity in the microenvironment for certain microbial community-members; in addition to the toxicity of soluble ions, the high dose of accumulated nanoparticles affect the microniche. It was shown that anorthosite-forming minerals such as pyrite, olivine, and pyroxene may cause nucleic acid degradation via surface free radicals generated (Xu et al 2013 ) and promote rupture of lipid vesicles (Xu et al 2009 ).…”

Biofilm-forming microbial communities are known as the most robust assemblages that can survive in harsh environments. Biofilm-associated microorganisms display greatly increased resistance to physical and chemical adverse conditions, and they are expected to be the first form of life on Earth or anywhere else. Biological molecules synthesized by biofilm -protected microbiomes may serve as markers of the nucleoprotein life. We offer a new experimental model, a kombucha multimicrobial culture (KMC), to assess a structural integrity of a widespread microbial polymer - cellulose - as a biosignature of bacteria-producers for the multipurpose international project "BIOlogical and Mars Experiment (BIOMEX)", which aims to study the vitality of pro- and eukaryotic organisms and the stability of organic biomolecules in contact with minerals to analyze the detectability of life markers in the context of a planetary background. In this study, we aimed to substantiate the detectability of mineralized cellulose with spectroscopy and to study the KMC macrocolony phenotype stability under adverse conditions (UV, excess of inorganics etc.). Cellulose matrix of the KMC macrocolony has been mineralized in the mineral-water interface under assistance of KMC-members. Effect of bioleached ions on the cellulose matrix has been visible, and the FT-IR spectrum proved changes in cellulose structure. However, the specific cellulose band vibration, confirming the presence of β(1,4)-linkages between monomers, has not been quenched by secondary minerals formed on the surface of pellicle. The cellulose-based KMC macrocolony phenotype was in a dependence on extracellular matrix components (ionome, viriome, extracellular membrane vesicles), which provided its integrity and rigidness in a certain extent under impact of stressful factors.

“…We choose to specifically study aerobic rock weathering organisms based upon their relevance to the sites sampled (primarily rock-air interfaces). Phenotypic traits were chosen based upon either their known importance in microbial rock weathering of shale (Kalinowski et al 2006;Spoalore et al 2011;Włodarczyk et al 2015) or of rock weathering more generally (Uroz et al 2009;Gadd, 2010;Carmichael et al 2013), and based upon the availability of agar plate phenotypic assay methodology.…”

“…Furthermore, microbial rock weathering activity has been indicated to increase environmental pollution from mining wastes (Wengel et al 2006;Kalinowski et al 2006) and to contribute to rock expansion in shale bedrock, causing significant damage to infrastructure (Anderson, 2008;Hoover and Lehmann, 2009). Such application-focused studies often quantify the biologically enhanced rate of elemental leaching from rock as a measure of the weathering potential of individual microbial strains (Tasa et al 1997;Anjum et al 2010) or microbial communities (Lee et al 2005;Matlakowska et al 2012;Włodarczyk et al 2015). These studies have revealed numerous microbial rock weathering mechanisms including the oxidation of iron (Tasa et al 1997, Grobelski et al 2007Spoalore et al 2011) secretion of siderophores (Kalinowski et al 2006, Włodarczyk et al 2015) and organic acid production (Anjum et al 2010;Włodarczyk et al 2016) that result in the enhanced dissolution and degradation of shale.…”

Microbial rock weathering of shale forms an important part of global biogeochemical cycling and soil formation. Culture-independent analyses have revealed diverse microbial communities in weathered shale environments, yet few studies have attempted to discern the functional ecology of such communities in relatiFon to their rock weathering capabilities. In this study, phenotypic plate assays were used to determine the abundance of microbes with different rock weathering phenotypic traits in weathered shale environments. A physicochemical parameter (pH) is shown to influence the abundance of aerobic rock weathering microbes in weathered shale. Iron and manganese oxidizers were restricted to acidic environments, while siderophore producing and alkaline phosphatase producing microbes were largely confined to pH neutral environments. Furthermore, a clear separation in the spatial distribution of aerobic iron oxidizing and siderophore-producing microbes, as defined by a pH gradient across the sites sampled, was demonstrated. Phylogenetic analysis of isolates revealed that siderophore producing and alkaline phosphatase producing bacteria belonged to commonly identified rock weathering genera including Arthrobacter, Pseudomonas and Streptomyces. These results enhance our understanding how physicochemical parameters can define the composition and rock weathering potential of microbial communities.
