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.

甲酸盐是一种微嗜氧或厌氧鞭毛虫群，其多样性已被环境DNA分析揭示。到目前为止，所有被研究的fornicates生物的细胞结构都没有典型的有氧呼吸线粒体，而是有减少的线粒体，这表明fornicates是理解线粒体减少过程的细胞进化的合适模型系统。然而，由于目前仍有一些已在实验室中分离和培养的淫虫，我们试图通过探索自然环境来建立新的淫虫培养物。在本项目中，我们建立了10多种新的微生物培养物，其中包括几种fornicates，并描述了其中的一部分。
