项目摘要

This research has been highlighted in the Nikkei. My interview has been published in the newspaper highlighting the PMFC. My interview has also telecast in the FM Kirara radio. Bioelectricity generation from big tree microbial fuel cell has been studied for this current research. There was 2 big Challenges during this research:1. How to place/set up the plant microbial fuel cell in a grown up tree? As the root systems of a big tree has already grown up, it is impossible to set the anode under the root system of a tree.2. How to increase the amount of generation of voltage and power from a big tree?The last year's research, we used two different types of big tree named Kurogane and Mukonoki for the research. It has chosen because the Kurogane is an ever green tree and Mukonoki is deciduous tree. The evergreen plant can generate more electricity throughout the year. However, the deciduous trees can generate less electricity due to its fallen leaves and change of color during the winter or the autumn time.For the first challenge, we set up bio-battery surrounding the tree. The biobattery were connected with the series connection. The food for the bacteria will be received by the help of the root extrudates. It was found that the bioelectricity can be generated from the big tree. The amount of the maximum voltage generation is 100000mV from one tree of Kurogane. However, it was seen that the for the Mukonoki, the voltage generation slightly dropped from the autumn and from the winter when the color of the trees started to change and the fallen down.

《日经新闻》（Nikkei）对这项研究进行了重点报道。我的采访发表在报纸上，重点介绍了PMFC。我的采访也在FM基拉拉电台播出。本课题以大树微生物燃料电池发电为研究对象。在这项研究中有两大挑战：1。如何将植物微生物燃料电池放置/设置在一棵成熟的树上？因为大树的根系已经长大，所以不可能把阳极放在树的根系下面。如何增加一棵大树产生的电压和电力？在去年的研究中，我们使用了两种不同类型的大树，分别是黑根树和木树。之所以选择黑根，是因为它是一棵常绿的树，而木树是一棵落叶树。这种常绿植物一年四季都能产生更多的电力。然而，落叶树在冬季或秋季由于落叶和颜色的变化而产生的电力较少。对于第一个挑战，我们在树周围设置了生物电池。生物电池采用串联方式连接。细菌的食物将通过根部挤出物的帮助而获得。人们发现这种大树可以产生生物电。每棵黑根树产生的最大电压为100000mV。然而，可以看出，对于木树来说，从秋天和冬天树木颜色开始变化和倒下时，电压产生略有下降。
