Humic acid (HA), a byproduct formed during the biological conversion of organic matter into biogas in anaerobic digestion (AD) process, contains complex structures and redox functions. However, evolution mechanism HA its interaction with CH4 production AD process have not been fully explored, particularly respect to various substrates temperature conditions. In this study, we investigated evolu...

Abstract As a result of socio-economic changes and land abandonment, the main ecological driver Carpathian landscape is progression natural forest succession process. Thus, aspects this process have become worthy attention, especially in context carbon sequestration management protected areas. Soil processes, within topsoil, are some most susceptible to change, due accumulation organic matter d...

The investigation of the mechanisms organic matter transformation in compost fertilizers is an urgent task modern soil ecology and chemistry. main components such are newly formed, weakly humified labile humic acids (HAs). objective study to determine mechanism converting formed HAs into forms with increased resistance microbiological biochemical influences. Obtained during plant residues decom...

The life of lakes in winter is still insufficiently studied. purpose this article a comparative analysis the quantitative development planktonic and benthic communities abiotic conditions their existence during ice-covered period two small (<1 km2) northern that differ greatly morphometry degree water humification. A significant difference was revealed seasonal dynamics plankton studied lake...

Studies the effects of exposure to light of the laser diode Melles Griot (λ = 670nm), He-Ne laser (λ = 632.8nm) and argon laser (λ = 514nm) on selected soil micro-organisms, fungi that destroy old manuscripts, pictures, stone, etc. and on humification and mineralization of soil samples. Also studies exposure effects on seed growth and biomass production of a few species of cultivated plants and...

Metal contamination from coal ashes (CAs) is widely recognized as a significant environmental concern. To learn more about metal detoxification and accumulation potential of earthworm species, metal-rich tea factory coal ashes (TFCA) were fed to Eisenia fetida and Lampito mauritii by employing a fluorescent tag detection method. Fascinatingly, on feeding fluorescence probed Zn and Cd along with...
