Abstract
When grown in batch culture for a prolonged period (up to 11 months), the cells ofIsochrysis aff.galbana (Isochrysis Tahitian strain T. Iso) lost their capacity to divide and became enlarged, with a reduction in the content of photosynthetic pigment and photosynthetic capacity. Upon returning to fresh medium, the cells of a 11-month-old culture regained their capacity to divide within 3 days under light conditions. The resulting cells possessed similar size, photosynthetic pigment and photosynthetic capacity as those of logarithmic growth phase. The results suggest that the aged cultures ofIsochrysis can be used as starter cultures for the production of live food for aquaculture animals.
