[Predation of micro-protozoa on bacteria in Taihu Lake].
With dilution method, this paper studied the predation of different size micro-protozoa on bacteria in Taihu Lake, and approached the effects of the predation on bacterial growth and of the water temperature on the predation. The results showed that in the water body of Taihu Lake, the predation rate of micro-protozoa with its size less than 32 microm was 5.07 d(-1), and the nano-size (less than 16 microm) protozoa contributed about 90.7%. The predation of nano-protozoa reduced the abundance of bacteria significantly. With the increase of water temperature, the predation rate of nano-protozoa and the growth rate of bacteria increased obviously.
