  Researchers Develop High-throughput Method for Rapid Detection of Pesticide Residues

  Researchers from the Institute of Applied Ecology, Chinese Academy of Sciences established a high-throughput method for the rapid detection of pesticide residues (i.e. Chlorpyrifos and Carbofuran) in water. This method combined Quantum Dot labeled Molecularly Imprinted Polymer (QD-MIP) with Flow Cytometry (FC) technology.

  Researchers Isolate Biosurfactant-producing Bacterial Strains Showing Potential for Microbial Enhanced Oil Recovery

  A new study led by researchers from the Institute of Applied Ecology, Chinese Academy of Sciences indicates that a bacterial strain isolated from Xinjiang oil reservoir can efficiently produce biosurfactant under anaerobic (oxygen-free) or high pressure conditions and thus is promising for applications in microbial enhanced oil recovery (MEOR).

  Researchers Isolate a new Pseudomonas Strain that Can Produce Biosurfactants without Air Injection

  Researchers from the Institute of Applied Ecology of CAS isolated an indigenous strain, Pseudomonas aeruginosa DQ3 from Daqing oil reservoir production water. They found that the strain could anaerobically (non-oxygen needing) produce biosurfactant through bioaugmentation.

  Scientists Find Unexpectedly High N Isotope Fractionation during Denitrification in Forest Soils

  Denitrification has been considered a major process removing available N from ecosystems and also a major mechanism leading N limitation of ecosystems. However, the denitrification rates are difficult to quantify due to the lack of direct determination method of denitrification rate from the ecosystem scale.

  Scientists Find Effect of Nitrogen deposition on Soil Microbial Diversity

  N deposition is one of the important factors affecting the global change. Research shows that the N deposition will increase continually in the coming decades. By simulation of N deposition experiment, in lab or field, Scientists have got some knowledge on changes in nutrient cycling of terrestrial ecosystem, plant productivity, plant diversity and soil microbe biomass under increased N deposition.

  Determining the main drivers of coarse woody productivity in temperate mixed forests

  As the main part of terrestrial biosphere, forest ecosystems play an important role for the global regulation of carbon, a substantialportion of which is maintained in above-ground biomass. Yet, it is still poorly understood what factors are drivingforest aboveground biomass productivity. While it is well understood forest productivity may be simultaneously driven by different abiotic factors (i.e. soil nutrients) and biotic factors (i.e. the diversity, trait composition and initial stand biomass) at local scale, the relative strengths of thesedrivers have not been investigated in temperate forests.
