Predictive modeling of biomass production by Spirulina platensis as function of nitrate and NaCl concentrations

Effects of nitrate (2.0, 2.5, and 3.0 g L−1) and salt (0.5, 1.0, 1.5, 2.0 g L−1) concentrations on biomass production by Spirulina platensis was examined in the Schlösser medium. The highest (p < 0.001) biomass yields and chlorophyll a content was observed at 2.5 g L−1 nitrate and 1.5 g L−1 NaCl as 3.495 g L−1 and 29.92 mg L−1, respectively. Increment rate of biomass production was especially found between 72 and 216 h. Modified Richards,...
