Continuous axenic cultures were established of Trichonympha sphaerica, a cellulose-digesting symbiotic protozoon in the gut of a termite. The cultured flagellates harbored no endosymbiotic bacteria and metabolized cellulose to acetate, carbon dioxide, and hydrogen. Thus, the cellulolytic activity of this flagellate is an inherent property and is not dependent on endosymbiotic bacteria.
连续建立了纤维素消化共生原生动物球形滴虫的无菌培养。培养的鞭毛虫没有内共生细菌,将纤维素代谢为乙酸盐、二氧化碳和氢气。因此,这种鞭毛虫的纤维素酶活性是固有性质,不依赖于内共生细菌。
