概要。来自草履虫的内共生藻类添加到培养基中后，会被携带小球藻的草履虫以 2,000 个藻类/有机体/天的速度摄入。当将藻类添加到培养基中时，草履虫生长得更快，这表明摄入的藻类被纤毛虫消化和同化（G = 有藻类的 40 小时，而没有藻类的为 190 小时）。纤毛虫对外源藻类的消化与这些藻类在正常生长条件下的存活形成对比。这表明内源藻类的保护与其在周围藻周液泡中的位置有关。
SYNOPSIS. Endosymbiotic algae from Paramecium bursaria when added to the culture medium are ingested by Chlorella-bearing P. bursaria at a rate of 2,000 algae/organism/day. That the ingested algae are digested and assimilated by the ciliates is suggested by the more rapid growth of Paramecium when algae are added to the medium (G= 40 hr with algae compared to 190 hr without). The digestion by the ciliates of exogenous algae contrasts with the survival of these algae under normal growth conditions. It is suggested that the protection of the endogenous algae is related to their location in peripheral perialgal vacuoles.
