摘要：
Twelve species of ubiquitous soil and water bacteria were randomly selected as substrates for a soil ciliate. Six species (particularly Escherichia coli and Aerobacter aerogenes) supported a flourishing protozoan population, while the remaining six (predominantly of the genus Arthrobacter) were of meagre nutritive value. Preliminary investigations indicate the presence of a toxic cytoplasmic principle that limits protozoan predation. This factor may account for the universal distribution and persistence of Arthrobacter while their nutritive attractiveness may explain the rapid disappearance of coliforms from soil and water. © 1969.
