“…With the 16s rRNA gene amplification and sequencing advances, the metagenomic structure and function of microbial communities inhabiting its bituminous shale and non-bituminous (limestone) rocks were investigated. The geomicrobiology of the Monte San Giorgio shale is similar to that of oil shale by-products - despite their geologically different origins - from Brazil (Irati Formation) 23 . The identified phyla Acidobacteria, Actinobacteria, Bacteroidetes, Firmicutes, Nitrospirae, Proteobacteria, Chloroflexi, Cyanobacteria, Deinococcus-Thermus, Spirochaetes Gemmatimonadetes, Planctomyces , and Thermotogae were also present in the black shale samples of Chengkou County, China, which covered the bottom zone toward the surface regolith 24 .…”

Organic-rich laminated shales and limestones from the Monte San Giorgio (Lugano Prealps, Switzerland) are known as famous fossil lagerstätten for excellently preserved fossils from the Middle Triassic Period. The various bituminous shales from Monte San Giorgio are thermally immature and rich in diverse organic compounds, which provide unique substrates for active soil microbial communities. We selected the Cava superior beds of the Acqua del Ghiffo site for this study. To investigate its microbial structure and diversity, contig assembly, Operational Taxonomic Units (OTUs) clustering, and rarefaction analysis were performed for bacterial 16S rDNA preparations from bituminous and non-bituminous limestone strata with the MetaAmp pipeline. Principal coordinates analysis shows that the microbial communities from the bituminous strata differ significantly from limestone samples (P < 0.05 Unifrac weighted). Moreover, metagenomic tools could also be used effectively to analyze the microbial communities shift during enrichment in specific growth media. In the nutrient-rich media, one or few taxa, mainly Proteobacteria and Firmicutes, were enriched which led to the drastic diversity loss while oligotrophic media could enrich many taxa simultaneously and sustain the richness and diversity of the inoculum. Piphillin, METAGENassist and MicrobiomeAnalyst pipeline also predicted that the Monte San Giorgio bituminous shales and oligotrophic enriched microbiomes degrade complex polycyclic aromatic hydrocarbons.

“…Brazilian researchers De Goes et al ( 2018 ) stated that actinobacteria , firmicutes , and proteobacteria dominate in the bacterial content of the unconventional oil/gas fields in St. Matthew of the South and even consider the possibility of using this bacterial mass as a component of the complex agricultural nutrient.…”

From Minerals to Simplest Living Matter: Life Origination Hydrate Theory

Long since, people tried to solve the mystery of the way that led to the appearance and propagation of living entities. However, no harmonious understanding of this mystery existed, because neither the scientifically grounded source minerals nor the ambient conditions were proposed and because it was groundlessly taken that the process of living matter origination is endothermal. The Life Origination Hydrate Theory (LOH-Theory) first suggests the chemical way capable of leading from the specified abundant natural minerals to origination of multitudes of multitudes of simplest living entities and gives an original explanation for the phenomena of chirality and racemization delay. The LOH-Theory covers the period up to origination of the genetic code. The LOH-Theory is grounded on the following three discoveries based on the available information and on the results of our experimental works performed using original instrumentation and computer simulations. (1) There is the only one triad of natural minerals applicable for exothermal thermodynamically possible chemical syntheses of simplest living-matter components. (2) N-base, ribose, and phosphdiester radicals and nucleic acids as whole are size-compatible with structural gas-hydrate cavities. (3) The gas-hydrate structure arises around amido-groups in cooled undisturbed systems consisting of water and highly-concentrated functional polymers with amido-groups.The natural conditions and historic periods favorable for simplest living matter origination are revealed. The LOH-Theory is supported by results of observations, biophysical and biochemical experiments, and wide application of original three-dimensional and two-dimensional computer simulations of biochemical structures within gas-hydrate matrix. The instrumentation and procedures for experimental verification of the LOH-Theory are suggested. If future experiments are successful, they, possibly, could be the first step on the way to industrial synthesis of food from minerals, i.e., to execution of the work that is performed by plants.
