Abstract Chlorella vulgaris was grown photosynthetically in batch culture under nitrogen sufficiency or nitrogen limitation. The starch content of the cells was measured as the amount of glucose released by enzymic hydrolysis of partially purified starch. Nitrogen sufficient algae contained approximately 20% of their dry weight as starch, whereas in nitrogen limited cells starch comprised up to 55% of the cellular dry weight. Starch production was pH dependent; optimal production of starch was achieved between pH 7.5 and 8.0. Optimal growth of C. vulgaris occurred at pH 7.0. Carbon yield experiments showed that for every gram of carbon consumed 0.5 g of starch (glucose) could be recovered.
