| Abstract: | he optimization of carbon sources, nitrogen
sources, inoculum size and initial pH for the heterotrophic culture of Chlorella vulgaris was
tested. The results indicate that as carbon sources, glucose and levulose are better, and as
nitrogen sources, KNO 3 and NH 4NO 3 are better. The inoculum size should be greater to
shorten the lag phase and lengthen the logarithmic growth time of Chlorella vulgaris, thus
increase the biomass. Furthermore, the most suitable initial pH is 6.5. |
