미세조류 Nannochloris oculata 의 성장과 지질 생산에 미치는 질소 농도와 광량의 영향Production of Biomass and Lipid Using Microalga Nannochloris Oculata Under Different Conditions of Nitrogen and Irradiance
Increasing demands on fossil fuel have led to the unprecedented attraction to microalgal biofuel as an alternative
energy. In this study, we investigated growth and lipid productions of microalga Nannochloris oculata under various
carbon dioxide or nitrogen source concentrations and irradiance conditions. Biomass production of N. oculata was
highest under 2% CO2 with 0.3 flow rate (vvm). In addition, biomass productivities were proportional to the concentration
of nitrogen source, whereas lipid biosynthesis was suppressed under higher nitrogen concentration (up to 50 mg/L).
High irradiation (160~180 μmol/m2·s) enhanced growth rate and lipid production of N. oculata.
