Symbioses of flagellates and bacteria in the gut of termites

白蚁肠道微生物群落中纤维素分解原生生物和细菌之间的各种关联被识别、检测和研究，以了解它们的协同进化关系。从少量人工分离的细胞开始进行全基因组扩增后，确定了两种内共生细菌的全基因组序列，揭示了它们之间的共生关系，涉及提供必需的含氮营养素。原生生物的初级代谢，有效地消除还原当量分子氢推断从他们的元转录组分析。

Various associations between cellulolytic protists and bacteria in the gut microbial community of termites were identified, detected, and investigated in terms of their co-evolutionary relationships. The complete genome sequences of two endosymbiotic bacterial species, determined after the whole genome amplification starting from small numbers of the manually isolated cells, disclosed their symbiotic relationship involving the provision of essential nitrogenous nutrients. The primary metabolism of the protists that efficiently eliminates reducing equivalents as molecular hydrogen was inferred from their meta-transcriptomic analysis.
