Article
The Oligocene Menilite Beds are considered the most important source rock for hydrocarbon accumulation in the Polish Carpathian region, whereas the Cretaceous Lgota Beds have been regarded as an additional potential source rock. Understanding their petrophysical and geochemical properties is essential for evaluating the hydrocarbon potential of the...

Framboidal pyrite has been a matter of interest of many studies due to its abundance in a wide range of environments and being a marker of redox conditions. However, the clear origin of framboidal pyrite remains unresolved. Our studies are preliminary laboratory investigations on the influence of the shape and physicochemical properties of bacte-ri...

Modern-day ocean circulation behaves as a complex forced convective system that is characterized by the decrease in water temperature but increase in water density with depth. The dissolved oxygen content – which initially decreases due to biological oxygen demand – also increases with depth. In contrast to the present-day scenario, we propose tha...

Due to changes in the energy market, it is projected that lignite excavation will be reduced in the near future. Cessation of exploitation is associated with restitution of natural water conditions and flooding of the resources left in the mines. Flooded lignite mines are a potential source of greenhouse gases (GHG) (CH4, CO2 and N2O), which should...

Methanotrophic bacteria (MB) are an important group of microorganisms, involved in the greenhouse gas (GHG) cycles. They are responsible for the utilization of methane, one of the main GHGs, which is released in large amounts (via biogenic and abiogenic processes) during coal formation. This study aimed to determine the main factors affecting the d...

Project
The project concerns the role of bacterial viruses (bacteriophages) in the processes of mineral phase precipitation in the aquatic environment. From the mineralogical and sedimentological point of view, bacteriophages have unique properties, among which the most important are very small sizes (on average 50-100 nm) and regular, crystal-like structure of the viral particles. Additionally, bacteriophages are widespread in the natural environment, in quantities significantly exceeding the number of bacteria. Therefore, it should be assumed that in aqueous environments, in which various mineral phases may precipitate (such as carbonates or sulphates and phosphates), viral particles may act as crystallization seeds initiating the precipitation of mineral phases. It can be also hypothesized that such precipitated mineral structures may differ from analogous structures crystallizing from an abiotic solution. So far, scientific studies in this area have mainly addressed the issue of the impact of bacterial cells and their associated structures on the formation and biotransformation of mineral phases, which led to numerous discoveries. The formation of characteristic mineral structures in the presence of microorganisms, whose origin was hitherto unclear, was shown. A classic example is the unique morphological forms of carbonate minerals. The presence of these forms in the natural environment can be regarded as indicator of certain sedimentary conditions because the presence of microorganisms was required for their formation. There is therefore no doubt that microorganisms can take an active or indirect role in the sedimentary environment and can initiate the precipitation of specific mineral phases. It is not clear, however, whether viral particles can also affect the precipitation processes. On the one hand they are very small and common in the environments, on the other hand metabolic activity does not exist in case of free viruses. Few studies to date are inconclusive and, in principle, the vast majority of them concern only carbonate issues. The impact of viruses on the other mineral groups such as sulphates, phosphates, silicates and sulfides were not studied at all.
Project
The current understanding of carbonate minerals precipitation is mainly based on abiotic or biotic (bacterial) precipitation of carbonate minerals. The additional virus participation in carbonate marine and freshwater environments and its scale is essentially unknown and in fact has only been reported from several localities where carbonate precipitation takes place in microbial mats and stromatolites or methane seeps. The main objective of this project is to determine virus distribution in carbonate-dominated temperature-, salinity- and mineralization-depended systems at various localities in Europe, the Bahamas and Qatar, spanning freshwater tufa of northern Calabria (the Parmenta stream, Corvino Valley), Slovakia (Lučky,) western Turkey (Honaz and Güney), Molasse Basin (river Moosach), Germany, United Kingdom (Lathkill Dale); hot-spring travertines of Bath in the United Kingdom, Pamukkale in Turkey, Egerszalók in Hungary, and Terme di Saturnia in Italy; normal marine modern stromatolites of Highborne Cay, Bahamas; and mesohaline microbial mats of Qatar by comparing mineralised shapes of capsids, nanoparticles and nanospheroids and their relationship to particular groups of virus strains, which would establish virus-based environmental proxies characteristic of freshwater cold or hot-spring and normal or mesohaline marine carbonate settings. The obtained results will be integrated with already available data from mesohaline microbial mats of Qatar, Lagoa Vermehla and Highborne Cay stromatolites. Revealing the distribution of viruses, their shapes and strains, will lead to establishing viral proxies characteristic of freshwater-marine carbonate environments and will significantly help to understand the controlling factors of virus distributions in modern carbonate settings with active microbial (bacteria and archaea) activity, the precipitation origin of carbonate nanospheroids and nanoparticles, thus answering the question about their origin. Planned and suggested interdisciplinary (biomineralogical, petrographic and molecular biology) methods bring for the first time an unprecedented opportunity to decipher the role played by viruses in carbonate marine and freshwater realm and establish new environmental proxies, particularly describing and characterizing factors controlling the virus distribution. The applied analytical methods will characterise the type of capsids, carbonate mineral phases and viral mineralisation products (nanoparticles, nanospheroids), and virus metagenomics. Thus, the pioneering nature of the project is differentiated carbonate mineral precipitation sites and the associated occurrence of viruses. In fact, the proposed project has a holistic approach showing a big picture needed to solve and answer the fundamental question about the origin of carbonate precipitates especially those deposited in microbially-active settings. Finally, the new data on virus participation in carbonate environments representing freshwater, hot-spring, normal and mesohaline marine systems will allow better understanding of the role played by viruses in the carbonate marine and freshwater realm.
