碩士 / 中原大學 / 土木工程研究所 / 100 / Microalgae has considerable potential as a source of biodiesel because of its attractive properties, i.e. fast growth, ability to use inorganic carbon by photosynthesis, transfer organic carbon to biomass and lipid products are similar to diesel, but does not produce sulfides pollutions.
In this study, the main object of study, Chlorella vulgaris, has characteristics of fast growth, and high lipid-containaing (5%¬¬ to 50% of biomass). It was cultured by batch under various light intensities(4000, 8000,15000lux) and medium(LE medium, Artificial wastewater modified Y. Feng et al., 2011). The optical density, number of algal cell, cell weight, chlorophyll-a, and lipid content were measured to identify the condition that maximized biomass production and lipid accumulation at various incubation times. Results demonstrate that 6000lux and 7 days incubation in LE medium yield the highest lipid concentration and lipid production rate (38.45%, 78.0±4.16 mg/L/d), average biomass growth rate μnet was 0.31d-1. Whether cultured by 15000lux, it was incubated for 4 days or 7 days will inhibit lipid concentration and lipid production rate. Algal was cultured 4 days or 7 day under 4000 lux of lipid concentration was no big difference. And 6000lux and 7 days incubation in Artificial wastewater (modified Y. Feng et al., 2011) yield the highest lipid yield and lipid production rate (325.8±56.4 mg/l、46.5±8.1mg/l/d).
