In 11 species of rumen ciliates belonging to nine genera of the family Ophryoscolecidae (order Entodiniomorphida) an ectosymbiosis with methanogenic bacteria was found. The bacteria could be identified as methanogens on the basis of the presence of specific fluorescent coenzymes (F350 and F420). This somatic interaction may reflect a metabolic interaction in which efficient interspecies hydrogen transfer benefits both partners.
在属于毛口科（内毛目）9个属的11种瘤胃纤毛虫中，发现了与产甲烷菌的外共生现象。基于特定荧光辅酶（F350和F420）的存在，这些细菌可被鉴定为产甲烷菌。这种体细胞间的相互作用可能反映了一种代谢相互作用，即高效的种间氢转移对双方都有益。
