Article
Organophosphonates (OPs) are a unique group of natural and synthetic compounds, characterised by the presence of a stable, hard-to-cleave bond between the carbon and phosphorus atoms. OPs exhibit high resistance to abiotic degradation, excellent chelating properties and high biological activity. Despite the huge and increasing scale of OP productio...

Simple Summary Deep subsurfaces such as caves and mines are extreme environments inhabited by specialized microorganisms that are able to cope with the adverse conditions caused by low moisture, and high pressure. Our research confirmed that one such site is the rocks surrounding the salt beds in the Wieliczka Salt Mine, where methane-oxidizing bac...

Looking for new, sustainable ways to utilize plastics is still a very pertinent topic considering the amount of plastics produced in the world. One of the newest and intriguing possibility is the use of insects in biodegradation of plastics, which can be named entomoremediation. The aim of this work was to demonstrate the ability of the insect Tene...
Article
Biochar promotes C sequestration and improvement of soil properties. Nevertheless, the effects of biochar addition on soil condition are poorly understood, especially with respect to greenhouse gas (GHG) emissions. A large proportion of GHG emissions derive from agriculture and, thus, recognition of the effect of biochar addition to soil on GHG emi...

Methane and carbon dioxide are one of the most important greenhouse gases and significant components of the carbon cycle. Biogeochemical methane transformation may occur even in the extreme conditions of deep subsurface ecosystems. This study presents methane-related biological processes in saline sediments of the Miocene Wieliczka Formation, Polan...
Article
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...
Article
The biofilms and water samples from a model installation built of PVC-U, PE-HD and cast iron pipes were investigated using standard heterotrophic plate count and 16S rRNA Next Generation Sequencing. The results of the high throughput identification imply that the construction material strongly influences the microbiome composition. PVC-U and PE-HD...
Article
Biological methane production from coal seams through their biological conversion is one of the methods that have been postulated to utilize unmineable resources. Furthermore, energy production from methane is considered less environmentally-harmful than the combustion of coal. In the current study, meta-bituminous coal extracted from the Upper Sil...

A b s t r a c t. The reduction in greenhouse gas emissions from agriculture is of particular importance at present. In recent times, biochar addition to the soil was suggested as a means of mitigating greenhouse gases emissions from arable fields. More specifically, biochars with useful properties and those produced from easily available waste mate...
Article

Biogas production and microbial community structure were analyzed as an effect of biochar addition to a fermentation sludge containing sugar beet pulp. Positive effects of the treatment including an increase in process efficiency and better biogas quality were noted. The effect of biochar on AD (anaerobic digestion process) microbial communities wa...
Article
Coal deposits comprise a huge proportion of carbon sequestered within the Earth's crust. Many deposits are anthropogenically altered by mining operations. The changes in local hydrogeology include, first - water removal from the seam to enable excavations, second – restoration of natural water condition by cessation of water pumping. In each of the...

The objective of this review paper is to present the current state of knowledge about poly-3-hydroxybutyrate produced by methanotrophic bacteria. Methanotrophs are a large group of microorganisms, which live in different kinds of environment, but they preferably occupy places with high methane production, such as swamps, peat bogs, rice fields, or...

Methanogenesis occurs in many natural environments and is used in biotechnology for biogas production. The efficiency of methane production depends on the microbiome structure that determines interspecies electron transfer. In this research, the microbial community retrieved from mining subsidence reservoir sediment was used to establish enrichment...
Article
Microbial coal gasification is of great interest due to the necessity to develop more environmentally friendly methods of energy production. The two main lignite deposits in Poland (Bełchatów and Turów) have been studied for their natural methanogenic potential. The biological origin of gases occurring in the investigated strata was confirmed by ca...
Article

Methane emission from wetlands is responsible for about 24% of the total CH4 emissions. The value of emission is a result of the balance between the processes of methane formation (methanogenesis) and sinks (methanotrophy). The methanotrophic activity from well-aerated soil surface layers has been relatively well recognized. On the contrary, the ac...

The aim of the study was a statistical evaluation of the impact of selected soil factors − water potential (pF), total organic carbon content (TOC) and land use − on the total DNA content and dehydrogenase activity (DHA) in Mollic Gleysol. Additionally, we wanted to establish the interrelations between two of the most important biological parameter...

Full version to be downloaded up to 50 times: http://www.tandfonline.com/eprint/SRQssShHRxdmP6P4RNwt/full Carbon (C), geologically sequestered in coal, is gradually released to the atmosphere as CH4 and CO2. Recent anthropogenic activity (coal mining) has rapidly increased the rate of C reallocation from coal deposits into the atmosphere, which ha...
Article
Changes in atmospheric concentrations of gases including CH4, O3, NO2, SO2 are one of the most current issues, due to the observed global warming. The concentration of atmos-pheric gases is being monitored by satellite measurements and also by tropospheric air monitoring stations located at various geographical latitudes. Polish law and EU Directiv...
Article
Wetlands are one of the major sources of atmospheric methane. However, not all methane produced by methanogens reaches the atmosphere as a substantial amount of CH4 (1 to 90%) is recycled in soil aerobic zone by methanotrophic bacteria. It was found that methane oxidation is also conducted by methanotrophic bacteria endosymbionts of Sphagnum mosses...
Article
Carboniferous coalbed rocks originating from the Lublin Coal Basin (South-East Poland) were investigated for the presence and activity of aerobic methanotrophic bacteria. Laboratory studies of samples collected from 914 to 1004 m below earth's surface and performed at 30 °C, 100% water capacity (WHC) and 10% v/v headspace CH4 revealed microbial met...

The aim of our study was to identify the methanotrophic group of bacteria inhabiting coal mine rocks at the Jastrze{ogonek}bie-Moszczenica (Jas-Mos) coal mine, by application of molecular techniques: polymerase chain reaction (PCR) and fluorescence in situ hybridization (FISH). In the first stage of the experiment, methanotrophic activity (AM) of t...

Methane is one of the most important greenhouse gases. In spite of its low mixing ratio (1775 ppbv), it is responsible for 20-30% of global warming. However, factors influencing methane fluxes to the atmosphere from different sources are still under debate. One of the most important elements of the methane cycle are methanotrophic bacteria. This un...
Article
Methane is an atmospheric trace gas, which is estimated to contribute about 20% to global warming. Coal mining used to be regarded as attributing considerably to the anthropogenic emissions of that potent greenhouse gas. Recently discovered methanotrophic abilities of coalbed rocks brought a new argument to the discussion about the environmental im...
Article
Agriculture is a main source of nitrogen and phosphorus in both groundwater and surface waters. The increased input of fertilizers and animal waters has boosted agricultural crop production to a high level in many industrialized countries, but it has also contributed to increased nutrients flow from agriculture to surface and groundwater waters. Th...
