Microbial biomass specific growth rate

Microbial Biotransformation. Microbial population growth and substrate utilization can be described via Monod s (35) analogy with Michaelis-Menten enzyme kinetics (36). The growth of a microbial population in an unlimiting environment is described by dN/dt = u N, where u is called the "specific growth rate and N is microbial biomass or population size. The Monod equation modifies this by recognizing that consumption of resources in a finite environment must at some point curtail the rate of increase (dN/dt) of the population ...

Pitt s energy allocation model, in the form of Equation 36.2, is somewhat restricted for application in wastewater treatment. The value of jjL, the specific growth rate, is difficult to determine due to the variety of physiological states in the biomass, the variety of microbial species, each with different growth rates and substrate affinities.
