dc.description.abstractFive different light intensities of 50, 100, 200, 400 and 600 mu mol photon m(-2) s(-1) were applied on the vegetative cultures of Haematococcus pluvialis to determine the optimal light intensity, and the growth performance. While dry weight and total carotenoid amounts increased in parallel to the light intensities, total chlorophyll amount increased up to the irradiance of 200 mu mol photon m(-2) s(-1) (2.21 mg L-1), and no change was observed in the higher illuminations (mean value of 2.35 mg L-1). Interestingly, cell count increased in all the groups from the mean value of 3.45 x 10(4) cells ml(-1) on the 15th hour to 5.66 x 10(4) cells ml(-1) on the 18th hour, which coincided with the dark period. In conclusion, astaxanthin accumulation was triggered and cell number was decreased above the illuminations of 200 mu mol photon m(-2) s(-1) (12.73 x 10(4), 16.10 x 10(4), 19.73 x 10(4), 15.90 x 10(4) and 12,89 x 10(4) cells ml(-1) for 50, 100, 200, 400 and 600 mu mol photon m(-2) s(-1), respectively). In the experiment applied five different illuminations, optimal light intensity range for the vegetative stage cultivation of the cells was found to be 50 - 200 mu mol photon m(-2) s(-1), and the best growth was in the light intensity of 200 mu mol photon m(-2) s(-1).
