化石燃料的枯竭是一个严重的全球性问题。开发新的生物质燃料，而不是从粮食，如玉米和甘蔗，是一个迫切的必要性。水生微生物具有易于培养和富含燃料的特点，有望成为生物质燃料的原料。其生产过程大致分为栽培、提取油成分和提炼燃料。然而，目前没有种植的制造过程效率低下。本研究将脉冲功率技术应用于微生物生物质燃料的生产过程，即微生物的培养和提取过程。利用纳秒级脉冲电场对微球进行预处理，以提高微球的培养速度和改变微球的组成。在本实验中，处理7天后，大量处理样品的细菌密度高于阴性对照样品。电穿孔技术是在细胞膜上开孔的技术，是生物技术中重要的细胞调控技术。在另一个实验中，将脉冲功率施加到电穿孔器以提高利用电穿孔的组分提取过程的效率。采用不同脉冲长度的脉冲功率来考虑这种影响。
The depletion of fossil fuel is a serious global problem. The development of new biomass fuel, which is not made from foods as corn and sugar cane, is an urgent necessity. For the easiness of the cultivation and the richness for containing fuel, hydrophytic microalga is expected as a crude material for biomass fuel. The manufacturing process is sketchily classified into cultivation, extraction of oil component and refinement of fuel. The manufacturing process without cultivation is, however, inefficient at present. This study applies pulsed power technology to the production process of biomass fuel made from microalga, which is the cultivation and extraction process. Nanosecond pulsed electric fields are applied to the microalga to anticipate increment of cultivation speed and modification of component. In this experiment, the alga density of large number of treated samples was higher than that of negative control samples after seven days of the treatment. The technology to open up pores on cell membrane is called electroporation, and it is important cell control technology in the biotechnology. In another experiment, pulsed power was applied to the alga to improve the efficiency of component extracting process with electroporation. The pulsed powers with different pulse length were used to consider the effect.
