چکیده انگلیسی
The green alga Botryococcus braunii is regarded as a potential source of renewable fuel due to its high lipid and hydrocarbon contents. However, the slow growth rate damaged its feasibility for biofuel production. In this study, a novel method of 'attached cultivation' was introduced to incubate B. braunii FACHB 357 (B race). A high biomass productivity of 6.5 g mâ2 dâ1 was achieved in single layer attached system at early stage of cultivation. At day 10, the biomass, lipid and hydrocarbon productivities were 5.5, 2.34 and 1.06 g mâ2 dâ1, respectively. Under nitrogen starvation condition, both of the contents of lipid and hydrocarbon were increased, whereas the profile of hydrocarbon kept almost unchanged, while the content for oleic acid (18:1) increased and linolenic acid (18:3) decreased. With a multi-layer photobioreactor, a biomass productivity of 49.1 g mâ2 dâ1 or a photosynthetic efficiency of 14.9% (visible light) were obtained under continuous illumination of 500 μmol mâ2 sâ1.
