Outline of Final Research Achievements

The electrofermentation process is a biomanufacturing process that utilizes bacteria that eat electricity (electrode oxidizing bacteria; EUB) and bacteria that generates electricity (electrode reducing bacteria).In this study, we aimed to improve the electro-fermentation process by isolating two types of bacteria that contribute to the enhancement of electron flux in the electroreduction tank (4.1-4-2 in the main text of the report), cultivating an accumulation of aerobic EUB that contribute to the enhancement of electron flux in the cathode chamber (4-3), the development of solid phase culture system to expand the bioresources of EUB (4.4), and the establishment of a genome editing systems for EUB to accelerate the genetic modification of EUB (4.5).

Academic Significance and Societal Importance of the Research Achievements

電気発酵プロセスは廃棄物系バイオマスをはじめとする余剰なエネルギー・物質を有価物に変換するデバイスである。本研究遂行により複数の電極酸化・還元細菌の分離株及び集積物が得られた。本成果は電気発酵プロセスの高度化に直接利用しうる重要な成果である。また本研究遂行で得られた最大の成果は好熱性電極酸化細菌であるMoorella属細菌に対するゲノム編集システムが構築できたことにある。本成果により従来遺伝子操作が困難であった当該属に対し自在な操作が可能となり、従ってバイオものづくりプロセスとして今一層の高度化につながる可能性がある。
