Simultaneous consumption of bacteria and dissolved organic matter byTetrahymena pyriformis.

abstract：:The quantitative uptake of latex beads of different sizes and of live cells by 14 species of ciliates was studied. The functional response (uptake rate as function of food particle concentration) can be fitted to a hyperbolic function and this can be explained in terms of the function of the mouth apparatus.
