Abstract
Small ciliate protozoa of the genus Uronema were separated from labeled bacteria by means of a discontinuous sucrose gradient. More than 98% of the radioactivity associated with the bacteria was found in the upper portion of the gradient, whereas the remaining portion of the gradient contained the ciliates.
摘要
通过不连续蔗糖梯度从标记细菌中分离出了纤毛虫属的小型纤毛虫原生动物。与细菌相关的放射性物质中，超过98%存在于梯度的上部，而梯度的其余部分则含有纤毛虫。
