Abstract

The biflagellated cells of the alga, HAEMATOCOCCUS PLUVIALIS, is greenish during its growth phase, and turn into reddish cysts, under unfavourable circumstances, due to accumulation of kelocarotenoid ASTAXANTHIN. We investigated the effects of the LIGHT INTENSITY on the ASTAXANTHIN production in two strains isolated in Iran (TMU) and Germany (SAG). Red cysts of these algae were preserved in agar medium. We cultivated, these strains in liquid culture medium under controlled conditions. The results showed transformation of green biflagellated moving cells to green immobile cells and then to red cysts in both strains, followed a different pattern, depending on incubation time and light intensities used. The accumulation of ASTAXANTHIN in the TMU strains was 2.5-3 fold more than that of the SAG-strain. This could be interpretedas a specific adaptation of TMU-strain to the habitat with high LIGHT INTENSITY, which in turn could be correlated with the increase in the number of cells
