Production and characteristics of typical taste and odor (T&O) compounds by Microcystis aeruginosa were investigated. A few terpenoid chemicals, including 2-MIB, beta-cyclocitral, and beta-ionone, and a few sulfur compounds, such as dimethyl sulfide and dimethyl trisulfide, were detected. beta-Cyclocitral and beta-carotene concentrations were observed to be relevant to the growth phases of Microcystis. During the stable growth phase, 41-865 fg/cell of beta-cyclocitral were found in the laboratory culture. beta-Cyclocitral concentrations correlated closely with beta-carotene concentrations, with the correlation coefficient R-2 = 0.96, as it is formed from the cleavage reaction of beta-carotene. For dead cell cases, a high concentration of dimethyl trisulfide was detected at 3.48-6.37 fg/cell. Four T&O compounds, including beta-cyclocitral, beta-ionone, heptanal and dimethyl trisulfide, were tested and found to be able to inhibit and damage Microcystis cells to varying degrees. Among these chemicals, beta-cyclocitral has the strongest ability to quickly rupture cells.
