Microbial composition assessment of anaerobic biomass through methanogenic activity tests

Abstract

Some of these methods are quite simple (Valcke and Verstraete, 1983; De Jong, 1986; Field et al., 1988; Soto et al., 1993) but the sample volume needed is too high (500 m/G6C or larger). Several solutions were proposed to reduce the working volume and to automate the monitoring process (Owen et al., 1979; Shelton and Tiedje, 1984; Dolfing, 1985; Bonastre et al., 1987; Concannon et al., 1988; James et al., 1990; Grotenhuis et al., 1991; Rintala and Lepisto, 1992; Soto et al., 1993). Very small working volumes (30 to 125 m /G6C) lead to smaller amounts of Microbial composition assessment of anaerobic biomass through methanogenic activity tests Mohammad Jawed1* and Vinod Tare2 1Department of Civil Engineering, University of Durban-Westville, Private Bag X54001, Durban 4000, South Africa 2 Environmental Engineering and Management Programme, Department of Civil Engineering, Indian Institute of Technology Kanpur, Kanpur - 208016, India Abstract Maintenance of sufficient methanogenic populations is critical for stable performance of anaerobic systems.
