Fornicates are a micro aerophilic or anaerobic flagellate group of which diversity has been revealed by environmental DNA analyses. All fornicate organisms whose cellular structures were investigated up to recently have no canonical mitochondria with aerobic respiration, but instead have reduced mitochondria, suggesting that fornicates are an appropriate model system to understand cellular evolution of the reducing process of mitochondria. However, since there still are a few fornicate organisms which have already been isolated and cultured in laboratories, we tried to establish novel cultures for fornicate organisms by exploring natural environments. In this project, we established more than 10 novel cultures for micro aerophilic or anaerobic eukaryotic organisms including several fornicates, and we described a part of them.

Fornicates是微型气膜或厌氧鞭毛群，通过环境DNA分析揭示了多样性。所有最近对细胞结构进行研究的进攻生物都没有有氧呼吸的规范线粒体，而是线粒体降低的，这表明Fornicates是一个合适的模型系统，可以理解线粒体还原过程的细胞演化。但是，由于仍然有一些已经在实验室中孤立和培养的富型生物，因此我们试图通过探索自然环境来建立针对富aniques有机体的新颖培养物。在这个项目中，我们建立了10多种用于微型气膜或厌氧真核生物的新型培养物，包括几种临时性的生物，我们描述了其中的一部分。
