AB  - To address the combined effects of cadmium (Cd) and elevated CO2 on soil 
      microbial communities, DGGE (denaturing gradient gel electrophoresis) profiles, 
      respiration, carbon (C) and nitrogen (N) concentrations, loessial soils were 
      exposed to four levels of Cd, i.e., 0 (Cd0), 1.5 (Cd1.5), 3.0 (Cd3.0) and 6.0 
      (Cd6.0) mg Cd kg(-1) soil, and two levels of CO2, i.e., 360 (aCO2) and 480 (eCO2) 
      ppm. Compared to Cd0, Cd1.5 increased fungal abundance but decreased bacterial 
      abundance under both CO2 levels, whilst Cd3.0 and Cd6.0 decreased both fungal and 
      bacterial abundance. Profiles of DGGE revealed alteration of soil microbial 
      communities under eCO2. Soil respiration decreased with Cd concentrations and was 
      greater under eCO2 than under aCO2. Soil total C and N were greater under higher 
      Cd. These results suggest eCO2 could stimulate, while Cd pollution could restrain 
      microbial reproduction and C decomposition with the restraint effect alleviated 
      by eCO2.
