| Popis: | Previously, we have successfully produced biodiesel using the marine microalga Nannochloropsis sp. KMMCC 290 cultivated in a raceway open pond. Here, we investigated the effects of closed photobioreactors and operating variables on cell concentration and lipid content of the microalga to increase its lipid productivity. The flatplate photobioreactor (FPP) showed higher performance than bubble column and air-lift photobioreactors. Among the variables evaluated, light intensity, aeration rate, and carbon dioxide feeding significantly influenced cell concentration, whereas a simultaneous increase in light intensity and aeration rate, as well as carbon dioxide feeding noticeably increased the lipid content. The lipid productivity in the FPP was 26.7 × 10-3 g/L/day, which was 16.6 times higher than that produced by the microalga cultivated in the raceway pond, 4.8 times higher than that from the simple flask-grown control culture, and 2.1 times higher than that from the FPP under initial conditions. |
