In this experiment the effects of lead and lead-free petrol applied at the following doses of: 0, 2, 4 and 6 cm • kg' of soil on growth and development of triticale and biochemical properties of the soil were studied. For detoxication of petrol organic amendment with barley straw was applied. The experiment was performed in two experimental series with and without triticale cover. It was found ...

Abstract There are numerous manuals to guide practitioners in utilizing traditional additives the construction of road, rail and dam but they fall short specific guidance for non-standard additive-based ecofriendly cost-effective soil stabilization. Increased attention has recently been on use stabilizing weak soils due environmental cost concerns associated with additives. We summarize guideli...

Several microorganisms were isolated from soil/sediment samples of Antarctic Peninsula. The enrichment technique using (RS)-1-(phenyl)ethanol as a carbon source allowed us to isolate 232 psychrophile/psychrotroph microorganisms. We also evaluated the enzyme activity (oxidoreductases) for enantioselective oxidation reactions, by using derivatives of (RS)-1-(phenyl)ethanol as substrates. Among th...

A lichenase gene (mt-lic) was identified for the first time through function-based screening of a soil metagenomic library. Its deduced amino acid sequence exhibited a high degree of homology with endo-β-1,3-1,4-glucanase (having both lichenase and chitosanase activities), encoded by the bgc gene of Bacillus circulans WL-12. The recombinant lichenase overexpressed and purified from Escherichia ...

Abstract It has been widely assessed that the quality and quantity of nutrient supply growing system can strongly affect growth development plants, nutritional quality, levels minerals, phytochemicals, vitamins. The study was conducted on leaves wild rockets grown in soil soilless to examine effect conditions mineral fertilization doses content, enzymatic non-enzymatic antioxidants, oxidative s...

This study reports the effects of long-term elevated atmospheric CO2 on root production and microbial activity, biomass, and diversity in a chaparral ecosystem in southern California. The free air CO2 enrichment (FACE) ring was located in a stand dominated by the woody shrub Adenostoma fasciculatum. Between 1995 and 2003, the FACE ring maintained an average daytime atmospheric CO2 concentration...

in present study, it was determinated lc50 96-h and toxicity degree of diazinon in huso huso, then were evaluated effects of sub-lethal concentrations on tow general enzymatic indices including alanine and aspartate aminotransferase of plasma and one specific enzymatic index including tissue ache enzyme. the median lethal concentration, lowest observed effect concentration and maximum allowable...

The incorporation of biosolids to soil is a strategy aiming at the re-location of these materials in the environment with a useful end: soil fertilization. In this work, the response of two Argiudoll soils (one with more than 100 years of agriculture and the other, a virgin one) to biosolid incorporation was studied under laboratory conditions. To measure this response, soil enzymatic biodescri...

Soil microbial community plays a major role in removal of polycyclic aromatic hydrocarbons (PAHs) from soil, and bioremediation potentially offers an attractive economic approach to the clean-up polluted areas. To evaluate contribution different groups soil PAH degradation, enzymatic activity phospholipid fatty acids (PLFAs) were analysed mesocosm trial three soils (two natural one industrial) ...
