Kinetics methanogenesis

Fig. 33.4. Factors controlling rates of microbial activity in the simulation depicted in Figure 33.3, for acetotrophic sulfate reduction (top) and acetoclastic methanogenesis (bottom). Factors include the thermodynamic potential factor Ft, kinetic factors FD = wac/C ac + Kq) and FA = mso4/(mso4 + K A), and biomass concentration [A],...

Acetogenesis and methanogenesis Both steps have been extensively and successfully simulated. However, the incorporation of hydrogen, fiee ammonia, and pH effects on the kinetics of both steps can he further improved.
