Abstract

Using of the standard methods for the production of unicellular algae have high harvesting costs and in many cases is not affordable. Therefore chemical fertilizers could be considered as an appropriate alternative for the production of unicellular algae. In this regards, Haematococcus pluvialis, were transferred to each of the 3-liters container. The results showed that the specific growth rate, the cell division per day, carbon dioxide fixation efficiency, biomass and total biomass efficiency was significantly higher and lower in treatment 7 and 1 respectively (P<0.05). The highest protein (17.35%), fat (15.46%) and carbohydrate (6.42 and 8.01) content was observed in treatments 6, 7, 2 and 3, respectively (P<0.05). the highest chlorophyll a (44.60 mg/g FW) in treatment 5 and chlorophyll b (62.19 mg/g FW) carotenoid (152.73 mg/g FW) in treatment 3 (P<0.05).
