N and P contents in the culture media are macronutrients that can directly influence algal growth kinetics; furthermore, these macronutrients are closely related to lipid accumulation in microalgae. In this study, the N and P concentrations of the SE medium were significantly higher than those of the mBG11 medium (Table 1). Li et al. also reported that the algal biomass is positively correlated with N and P concentrations
