We studied the molecular diversity of β-glucosidase-encoding genes, microbial biomass, cellulase, N-acetyl-glucosaminidase, β-glucosidase, and β-galactosidase activities in the rhizosphere and bulk soil of two maize lines differing in nitrogen use efficiency (NUE). The maize lines had significant differences in diversity of β-glucosidase-encoding genes in(More)
In the past several years, industrial and agricultural activities have led to serious environmental pollution, resulting in a large number of contaminated sites. As a result, much recent research activity has focused on the application of bioremediation technologies as an environmentally friendly and economically feasible means for decontamination of(More)
Soil proteomics is facing problems such as low yields of protein extraction from soil and low protein identification rates as compared to theoretical estimates of soil proteome. This work aimed to evaluate the effect of soil-borne humic substances (HS) on the identification of model proteins with different properties, such as myoglobin (Mb), α-glucosidase(More)
Study of the changes in soil microbial biomass, enzyme activity and the microbial community structure in the rhizosphere of two contrasting maize lines differing in the nitrogen use efficiency (NUE). The Lo5 and T250 inbred maize characterized by high and low NUE, respectively, were grown in rhizoboxes allowing precise sampling of rhizosphere and bulk soil(More)
We studied the microbial functional diversity, biochemical activity, heavy metals (HM) availability and soil toxicity of Cd, Pb and Zn contaminated soils, kept under grassland or short rotation coppice (SRC) to attenuate the risks associated with HM contamination and restore the soil ecological functions. Soil microbial functional diversity was analyzed by(More)
We studied the effects of humic substances (HS) extracted from soil on the identification of the recombinant ovine prion protein (RecPrP) by denaturing (sodium dodecyl sulfate polyacrylamide gel electrophoresis [SDS-PAGE]) and native PAGE (N-PAGE), and mass spectrometry (MS), at various HS to RecPrP contact ratios. The results showed that the contact with(More)
The aim of the study was to determine if an As-contaminated soil, stabilized using zerovalent iron (Fe(0)) and its combination with gypsum waste, coal fly ash, peat, or sewage sludge, could be used as a construction material at the top layer of the landfill cover. A reproduction of 2 m thick protection/vegetation layer of a landfill cover using a column(More)
