The concentration of nitrogen in the diet Chu'13 medium that fills KNO3 5 different levels: 0.20, 0.40, 0.80, 1.60 and 3.20 g / l The results showed that algae can grow and produce biomass up. at concentrations of 1.60 g / l (0.93 ± 0.20) and the difference was statistically significant for all concentrations (p <0.05) except at concentrations of 0.80 g / l and when put to the test starch. found that the formation of starch in the diet Chu'13 medium nitrogen 0.20 g / l (12.64 ± 4.68% DW), no difference was statistically significant (p> 0.05) with 0.40 g / l with. 1.60 g / l and 3.20 g / l, except that 0.80 g / l, with the difference was statistically significant (p> 0.05).
