It was studied the growth of the cyanobacterium Microcystis sp. isolated from algal blooms of the Tacuary reservoir. The cultivation was performed in triplicate BG11 medium, average temperature of 25 ? 3 ? C, 0.8086 ?mol?s⁻??m⁻?, with a photoperiod of 14:10, pH of 7.10 and daily stirring. Isolation was performed by means of the pipette method and sequential dilutions. The isolated culture revealed a maximum growth rate of 0.357 days -1 and minimum of 0.12 day -1 on average doubling time of 4.124 days. During the analysis, the strain increased its density through the acceleration and exponential phases. It reflects in a short time that the strain is conserved with a high rate of cell evolution under controlled conditions; consequently, it contributes to the comprehension of the phenomenon behavior for its management or environmental control.
