Abstract

Spirulina platensis is useful because of having special amino acids balance for human and animal nutrition. This study was conducted to investigate the possibility of cultivating S. platensis by enriching the Persian Gulf water by nitrogen and carbon sources in a completely randomized design for 21 days. The experimental treatments were (1) seawater (control), (2) seawater enriched with urea, (3) seawater enriched with sodium bicarbonate, and (4) seawater enriched with sodium bicarbonate and urea. The results showed that there was a significant effect on biomass production between treatments 1 with 3, and 1 with 4 (P<0.05). An increase in biomass of the treatment four was maximized due to nitrogen and carbon supply, in comparison to others. According to the results, it can be concluded that the enrichment of the Persian Gulf water and its geographical location, the sea shores can be used for cultivation of S. platensis.
