Abstract


Research on the effect of technical and proanalyze fertilizers on the growth of Chlorella vulgaris was conducted in triplicates using a culture bottle containing 3 l of sea water at 30 ppt. The culture media were inoculated with Chlorella vulgaris at 104 cells/ml of initial density, lighted at 2000 lux, and incubated at 26°C. Results showed that the highest growth rate of C. vulgaris was obtained in medium added with anorganic proanalyze fertilizer with maximum density of 2.62 x 107 cells/ml at 9 days culture. Ammonia, sulphide, nitrate, nitrite, phosphate, iron, cuper, and cadmium contents were not exceed the maximum limit at the 13-day of culture.

Keywords
