Abstract

Abstract: Effects of flow velocity on growth of Microcystis aeruginosa incubated in water from the Taihu Lake were studied in laboratory.Results show that when the experimental conditions were set as 25 ℃ in temperature,3 300 lx in light intensity and 10 h/14 h in light cycle,the alga grew best with the flow velocity being 30 cm·s^-1.If the flow velocity rose or fell,growth of the alga was affected to a varying extent,and to a significant extent when the flow velocity reached to or beyond 50 cm·s^-1.

Key words: flow velocity, Taihu Lake, Microcystis aeruginosa
