An analytical model of a continuously fed, completely mixed Chlorella culture in which light is the factor limiting growth is presented. The conclusions from the theory are that in a culture of this type the population density is directly proportional to the retention time and the production rate is independent of retention time. Experimental data are presented to verify the theoretical conclusions.
The original mathematical model of microbial growth in the Chemostat is modified to describe continuous cultures in which the limiting nutrient is supplied at a rate independent of the dilution rate. The application of this model to continuous Chlorella cultures in which CO(2) is the factor limiting growth is discussed. The conclusions from the model are: (i) at a constant rate of CO(2) supply, the equilibrium population density is directly proportional to the retention time; and (ii) the production rate is directly proportional to the rate of CO(2) supply. Experimental data are presented to verify the theoretical conclusions.
