AB  - A stable aerobic microbial consortium, established by successive subcultivation, 
      was employed to solubilize the solid organic fraction in swine wastewater. In the 
      30 days' successive biological pretreatments, 30-38% of volatile solids and 
      19-28% total solids in raw slurry were solubilized after 10 hours at 37  degrees C. 
      Meanwhile, soluble chemical oxygen demand (COD) and volatile fatty acid increased 
      by 48%-56% and 600%-750%, respectively. Furthermore, the molecular microbial 
      profile of the consortium in successive pretreatment was conducted by denaturing 
      gradient gel electrophoresis (DGGE). The results indicated that bacterial species 
      of the consortium rapidly overgrew the indigenous microbial community of raw 
      water, and showed a stable predominance at the long-term treatment. As a 
      consequence of biological pretreatment, pretreatment shortened digestion time by 
      50% and increased biogas production by 45% compared to raw water in the anaerobic 
      process. The microbial consortium constructed herein is a potential candidate 
      consortium for biological pretreatment of swine wastewater to enhance biogas 
      production.
