Abstract
Several species of protozoa, during their logarithmic phases of growth, produce substances that prolong the logarithmic phase in other species. The effect is not as striking as the inhibition of growth caused by antibiotics, but a consistent 50-percent increase in growth has been obtained with Tetrahymena pyriformis in response to a factor produced by Colpidium campylum.
摘要
几种原生动物在其对数生长期会产生一些物质，这些物质能延长其他物种的对数生长期。这种作用不像抗生素引起的生长抑制那样显著，但对于梨形四膜虫来说，响应坎氏肾形虫产生的一种因子，其生长持续增加了50%。
