Suspension feeding in ciliated protozoa: Functional response and particle size selection.

abstract：:Thymidine and leucine incorporation into macromolecules of soil bacteria extracted by homogenization-centrifugation were measured after size-fractionation of the bacterial suspension through different sized filters (1.0, 0.8, 0.6, 0.4 μm). The specific thymidine incorporation rate was highest for the unfiltered and 1....
