Abstract：To figure out the reasonof severe odor problem in the water source of East Taihulake, the algae species and cell densities, as well as their correlationswith 2-MIBconcentration were investigated. Two dominated filamentous algae species in the water were identified according to16S rDNAdetection. The result indicated thatthe algae cell density and the concentration of 2-MIB were of high correlation with R2>0.85.Sometypical odor compounds producer Oscillatoriales (includingthe identified species Limnothrix and Planktothrix) and Synedraaccount for over 55% of the total algae cell numbers. In particular, the intracellular 2-MIB account for 68%of its total concentration, indicating the risk of intracellular 2-MIB release during the water treatment. In addition, the density of algae as well as the concentration of 2-MIB and ammonia nitrogen were decreased withthe increasing distance between sampling points and the aquiculture zone, suggesting that the high concentration of 2-MIB around the intakes wasprobably caused by the aquiculture activities.
