碩士 / 國立雲林科技大學 / 環境與安全衛生工程系碩士班 / 99 / Biomass Energy is currently the most widely used renewable energy. The main waste oil or used by plants to absorb sunlight for photosynthesis, the atmospheric carbon dioxide into sugars, converted into biofuel. Microalgae is considered to be a good source of bio-fuels, is available for photosynthesis of single-celled plants, compared to other biomass crops, can be fast and mass production of microalgae biomass and accumulation of oil in a large number of cells, and have more high optical efficiency, and therefore may completely replace the traditional fossil fuels, become a new source of energy. Fat content of different algae is not the same culture conditions in the control condition increased from 30 to 60% of algae dry weight. Algae can also absorb the greenhouse gas CO2 to achieve the objective of carbon reduction, therefore, not only the production of microalgae to produce biodiesel, the more a zero carbon emissions system.
Fat content due to the Nannochloropsis oculata can be as high as 58%, so this study intends to sp algae species as experimental, and with the increase in microbial activity electromagnetic fields to enhance substrate removal. Weak magnetic field density can enhance the cell density in the short, medium, and can stimulate algae absorb nutrients, on the magnetic properties of water to achieve the intended goals, and the total fat content of algae increase. The results show that adding the magnetic field can indeed improve the algae cell density to be the ball, but the body lipid content in the algae is reduced.
