Consortium methanogenic

Degradation of hex-l-ene has been observed in a methanogenic consortium (Schink 1985a) that converted the substrate into methane, and a plausible pathway involving hydration and oxidation was suggested.

Fig. 28.4. Degradation of phenol by a consortium of methanogens, as observed in a laboratory experiment by Bekins et al. (1998 symbols), and modeled using the Michaelis-Menten equation (solid line). Inset shows detail of transition from linear or zero-order trend at concentrations greater than KAy to asymptotic, first-order kinetics below this level. Broken line is result of assuming a first-order rather than Michaelis-Menten law.

Soil Under aerobic conditions, indigenous microbes in contaminated soil produced pentachlorocyclohexane. However, under methanogenic conditions, a-BHC was converted to chlorobenzene, 3,5-dichlorophenol, and the tentatively identified compound 2,4,5-trichlorophenol (Bachmann et al., 1988). Manonmani et al. (2000) isolated a microbial consortium from sewage and soil that could completely mineralize a-BHC in 14 d at 30 °C. The acclimated consortium could degrade up to 100 mg/L of a-BHC within 72 h at a degradation rate of 58 mg/L-day. 

A methanogenic consortium derived from municipal anaerobic digester sludge was placed into a reactor containing 1,1,1-trichloroethane. The reactor was operated at 20 °C on an average 50-d hydraulic retention time. Degradation followed first-order kinetics and reported rate coefficients for filtered and unfiltered supernatant from the settled consortium were 0.11 and 0.12/day, respectively. 1,1-Dichloroethane was the only product detected which accounted for 46% of the initial 1,1,1-trichloroethane concentration (Gander et al, 2002).
