A cost-effective bioconversion technology was developed to produce biogas from high strength organic waste such as swine waste. Swine waste was biologically treated to produce methane both in a pilot-scale anaerobic sequencing batch reactor and in continuous upflow anaerobic sludge blanket digesters. Dynamics of methanogenic populations weremonitored in the both digesters, at order and family levels, using real-time PCR based on the 16S rRNA gene (Yu et al., 2006). A high abundance of hydrogenotrophic methanogens was observed, with Methanobacteriales as the major group in the digesters, suggesting that hydrogenotrophic methanogenesis, with the syntrophic oxidation of volatile fatty acids, was a major route of methane formation in anaerobic process treating swine waste. This phenomenon was mainly attributed to the high ammonia and VFAs concentrations which are characteristics of swine waste (Bonin and Boone, 2006; Demirel and Scherer, 2008). These substances have a severe inhibitory effect mainly on aceticlastic methanogens. Consequently, the dynamics of methanogen population deduced by QPCR analysis showed good agreement with the digester conditions and major chemical profiles. These results emphasize that more attention should be devoted to quantitative investigation of methanogenic community dynamics and structure for better understanding of their roles and behaviors in anaerobic digesters treating swine waste (McHugh et al., 2003; Zheng et al., 2006).
