永續發展目標下以微重力下細菌適應性於微生物燃料電池開發應用

Abstract

21世紀，人類面臨來自社會以及自然氣候的全球化挑戰。在此其中，全球可利用能源的短缺問題吸引了越來越多科學家的關注。

细菌的生長取決於多種因素，例如溫度、濕度和氧氣含量。雖然科學家尚未完全理解微重力條件如何影響生物體的生存能力，但细菌的代謝過程對化學能轉化為電能至關重要，也在驅動微生物燃料電池（MFCs）中扮演著關鍵角色。透過微生物燃料電池（MFCs）、微重力應用和綠色能源的應用，人類得以建立可持續能源來源，同時減少溫室氣體排放並減少對化石燃料的依賴。這些措施在應對氣候變化方面扮演著關鍵的角色，有助於改善空氣品質和人類整體健康。

此外，將MFCs與微重力應用整合於太空和地球上，還有助於資源保護和廢物處理。這些成果與聯合國永續發展目標相一致：推動為所有人提供經濟、可靠、可持續和現代化的能源，從而提升人類生活品質。基於我目前在法國的實習專注於微流體技術在釀酒過程中的創新和使用優質酵母菌株，我相信MFCs、微重力應用、釀酒處理和綠色能源的研究合作擁有巨大的未來潛力。 我的研究探討微重力對微生物生長和微生物燃料電池電力生產效率的影響。我們與國立宜蘭大學機械與電機工程系合作，創建了一個隨機定位裝置來模擬微重力環境。透過在微重力條件下培養 E. coli 和 Shewanella Oneidensis MR-1，得以測量固定在微重力裝置上的微生物燃料電池不同的電壓值。我們假設在微重力條件下， E. coli 和 Shewanella Oneidensis MR-1的生長速度比正常重力環境下更快。實驗結果顯示，大腸桿菌的生長速率和MFCs的電力生產確實受到抑制。這是因為氧氣不足或是細胞無法均勻吸收營養物質導致。

21th century is a special period that the human beings meet the global challenge from both social problems and natural climate. Among them, the shortage of accessible energy attracts a lot of attentions from researchers.

Bacteria growth de¬pends on several factors such as te¬mperature, humidity, and oxygen le¬vels. Although scientists have ye¬t to fully comprehend how microgravity conditions affect organisms’ ability to thrive¬. It is also important to understand that bacteria's metabolic proce-sses are necessary in converting chemical ene¬rgy into electrical ene¬rgy, which plays a crucial role in powering microbial fuel ce¬lls (MFCs). By collaborating microbial fuel cells (MFCs), microgravity applications, and green energy, significant outcomes can arise for human beings. Through collaboration, sustainable e¬nergy sources are linke¬d while diminishing greenhouse¬ gas emissions and reducing depe¬ndence on fossil fuels. This crucial role¬ in tackling climate change leads to improve¬d air quality and overall human health. Moreover, resource¬ conservation and waste manageme¬nt are facilitated by integrating MFCs with microgravity applications both in space¬ and on Earth. These consequences align with the Sustainable Development Goal of ensuring access to affordable, reliable, sustainable, and modern energy for all, ultimately advancing the quality of life for humanity.

Given my current internship in France focusing on Microfluid sorting innovation for winemaking and the use of superior yeast strains, the research collaboration among MFCs, microgravity applications, winemaking treatment, and green energy holds great potential as a future direction of work.

This study investigates the effect of microgravity on the growth of microorganisms and microbial fuel cells' electricity production efficiency. Cooperating with Department of Mechanical and Electro-Mechanical Engineering at National Yilan University, we created a Random positioning machine to mimic microgravity condition. Demonstrating culture of E. coli and Shewanella Oneidensis that were shown to produce electricity in microgravity conditions and measurement of different voltage in MFC which is fixed at microgravity device. We hypothesis that the growth of E. coli and Shewanella Oneidensis is quicker than in normal gravity. The experimental results showed that the growth rate of E. coli and the electricity production of MFCs were indeed inhibited. This is caused by insufficient oxygen or the inability of cells to absorb nutrients evenly.
