Abstract
Growth characteristics ofScenedesmus acutusisolated from fish culture pond were investigated in various nutrient concentrations.
Cultivations were carried out at 25-30°C in continuous ligth illuurination with cool-white fluorecent lamps at 3, 000lx.
Maximum growth was obtained at an inidal pH value of 7.0 in Gorham's medium and 9.0 in modified Gorham's medium.
Nitrogen souces used urea, ammonium, nitrite and nitrate were significantly effective for the growth ofS. acutus. Final pH value at ammonium were4.1 or 9.0-10.0 at other nitrogen.A good growth was obtauied at concentration of 14mg/l for nitrogen and 62mg/l for phosphorus.
