The rumen ciliate Epidinium ecaudatum was cultured for 6 months in the presence of two strains of bacteria, starch, alfalfa, linseed oil meal, and buffered saline. The cultures required daily transfer and addition of fresh substrate. The protozoan degraded starch, soybean oil meal, linseed oil meal, and cottonseed oil meal, and the fermentation end products from the breakdown of starch were acetic and butyric acids with traces of formic, propionic, and lactic acids, carbon dioxide, and hydrogen. The relationship of E. ecaudatum to other species of rumen oligotrichs and bacteria is discussed.
瘤胃纤毛虫尾草履虫（Epidinium ecaudatum）在两种细菌菌株、淀粉、苜蓿、亚麻籽粕以及缓冲盐水存在的条件下培养了6个月。培养物需要每日转接并添加新鲜底物。该原生动物可降解淀粉、大豆粕、亚麻籽粕和棉籽粕，淀粉分解产生的发酵终产物为乙酸和丁酸，并伴有微量的甲酸、丙酸和乳酸、二氧化碳和氢气。文中讨论了尾草履虫与其他瘤胃寡毛目动物和细菌物种之间的关系。
