Effect of dilution rate, pH and temperature on the growth of Chlorella kessleri in a continuous autotrophic culture.
In a culture of Chlorella kessleri illuminated with a sodium vapour lamp at 33 degrees C and pH 6.5 the maximum rate of biomass production was 4.5 g L-1 d-1. Of the total volume of 3.6 L or the suspension 2.5 L were placed between two glass concentric cylinders surrounding the tube. Examples of the course of specific growth rate mu in the transient state following jump changes in the dilution rate, pH and temperature are presented. After a jump change of pH or temperature of the suspension maximal and minimal values, respectively, of mu are observed.
