Nitrogen (N) is widely distributed in the lithosphere, hydrosphere, atmosphere and biosphere. It a basic component of every plant cell as well microorganisms, proteins, nucleic acids chlorophyll. enters soil with organic mineral fertilizers, animal residues biological nitrogen fixation. There are various forms soil, this element usually transformed by microorganisms. The transformation compound...

Research was conducted in connection with the pressure exerted by man on environment through use of pesticides. The aim study to assess impact pesticides soil and evaluate effect these changes greenhouse gas emissions into atmosphere. research carried out sown oilseed rape. activity protease urease, ammonification, nitrification soil, as well CO2 (carbon dioxide) N2O (nitrous oxide) from were a...

Monitoring of surface water quality indicates deterio­ration its due to anthropogenic pollution. Among them, potassium stearate (PS) occupies a prominent place. The purpose the study is substantiate regulations in reservoirs on basis sanitary and hygienic assessment stearate, stability transformation, impact organoleptic properties water, condition, self-cleaning processes condition reservoirs....

Abstract The aim of the present study was to determine changes in organic nitrogen fraction liquid digestate during laboratory tests mono- and co-digestion. Three agricultural wastes were tested: distillery residue, cattle slurry corn silage. In mono-fermentation tests, initial total concentration depended on feedstock used. As a result hydrolysis ammonification matter contained feedstocks, the...

Hyperaccumulation of heavy metals is substantial in some hyperaccumulators; however, few studies have been conducted to reveal the effect light irradiation on variations representative amino acids and photosynthetic indices, which can represent antioxidant capacity plants during phytoremediation. The physiochemical responses Arabidopsis thaliana Cd stress were compared six treatments. results e...

After a shift of Bacillus subtilis from aerobic to anaerobic growth conditions, nitrate ammonification and various fermentative processes replace oxygen-dependent respiration. Cell-free extracts prepared from wild-type B. subtilis and from mutants of the regulatory loci fnr and resDE grown under aerobic and various anaerobic conditions were compared by two-dimensional gel electrophoresis. Prote...

Anaerobic digestion is a common method for reducing the amount of sludge solids in used waters and enabling biogas production. The wet oxidation process (WOX) improves anaerobic digestion by converting carbon into methane through oxidation of organic compounds. WOX produces effluents rich in ammonia, which must be removed to maintain the activity of methanogens. Ammonia removal from WOX could b...
