碩士 / 國立成功大學 / 化學工程學系碩博士班 / 101 / Microalgae have been considered as the promising feedstock for biofuel production, since they can assimilate atmospheric carbon dioxide and produce high value components. Particularly, Spirulina sp. show high contents of phycocyanin, chlorophyll a, β-carotene, polysaccharides and γ-linolenic acid.
The microalgae growth is mainly influenced by the temperature, light intensity, nutrients of medium and inoculum concentration, etc. After the cultivation, harvesting of these microalgae cells is a crucial step and it contributes to 20-30% of the total expenditure of biomass production.
In this study, we investigated the effects of light intensity, temperatures, grades of chemicals used, nitrogen sources, feeding strategies on the growth and phycocyanin production of Spirulina platensis. Due to size of Spirulina sp., we found that mesh screening (pore size = 37μm) is effective to remove biomass from medium. The removal efficiency would high than 80%.
