The influence of soil heavy metals pollution on soil microbial biomass, enzyme activity, and community composition near a copper smelter.
The environmental risk of heavy metal pollution is pronounced in soils adjacent to large industrial complexes. It is important to investigate the functioning of soil microorganisms in ecosystems exposed to long-term contamination by heavy metals. We studied the potential effects of heavy metals on microbial biomass, activity, and community composition in soil near a copper smelter in China. The...
متن کاملResponse of enzyme activities and microbial communities to soil amendment with sugar alcohols
Changes in microbial community structure are widely known to occur after soil amendment with low-molecular-weight organic compounds; however, there is little information on concurrent changes in soil microbial functional diversity and enzyme activities, especially following sorbitol and mannitol amendment. Soil microbial functional diversity and enzyme activities can be impacted by sorbitol and...
متن کاملEffects of plant species coexistence on soil enzyme activities and soil microbial community structure under Cd and Pb combined pollution.
The relationship between plant species coexistence and soil microbial communities under heavy metal pollution has attracted much attention in ecology. However, whether plant species coexistence could offset the impacts of heavy metal combined pollution on soil microbial community structure and soil enzymes activities is not well studied. The modified ecological dose model and PCR-RAPD method we...
متن کاملImpact of indigenous microorganisms on soil microbial and enzyme activities
The effect of Indigenous microorganisms (IMO’s) on the native soil was investigated in the present study. Supplementation of IMO’s suspension to the soil alters the physico-chemical, biological and enzyme properties of the soil. These alternations include decreases in P from 7.2 to 6.8, increase in electrical conductivity 0.36 to 1.21 (μmohs/cm), water holding capacity 0.36 to 2.2ml/g of soil o...
متن کاملNatural attenuation of zinc pollution in smelter-affected soil.
Previous synchrotron X-ray microprobe measurements of Zn speciation in contaminated and uncontaminated soils have identified phyllosilicate as the main sequestration phase. The emphasis now is focused on comparing the nature and properties of neoformed and geogenic phyllosilicate species to understand natural attenuation processes. Refined structural characterization of the two types of Zn-cont...
