In this study, Uiam-sediment(US) and Gongji-sediment(GS) were incubated to analyze the formation of phytoplankton community and occurrences of odorous compounds from benthic cyanobacteria. For the phytoplankton, 45 and 40 taxa were found in GS and US, respectively. The phytoplankton species detected in the harmful algae included Microcystis, Anabaena and Oscillatoria. As a result, a standing crop of phytoplankton appeared to be in the range of $0.9{\sim}71.8{\times}10^3$ cells/mL in GS, $0.8{\sim}51.2{\times}10^3$ cells/mL in US, and as the incubation progressed, benthic cyanobacteria was increased. The highest number of akinetes was shown in the initial incubation, and akinetes was reduced by 10% on day 4 of incubation start. After reduction of akinetes incubated for 4 days in US and 15 days in GS, Anabaena appeared from the surface water. Benthic cyanobacteria such as Oscillatoria tenuis, O. limosa and Lyngbya hieronymusii was dominant in GS (max. $3.96{\times}10^6cells/cm^2$) and US (max. $5.77{\times}10^6cells/cm^2$), forming cyanobacterial mats in sediment surface. Cyanobacterial mats were suspended after 10~12 days incubation in GS and US. Before and after the suspension of cyanobacterial mats, the concentration of geosmin was the highest in GS(115 ng/L) and US(175 ng/L). In the second suspension of cyanobacterial mats in GS, the concentration of 2-MIB was increased to the range of 22~92 ng/L.
