Abstract

During cyanobacterial blooms, a portion of the biomass would sink to the sediment-water interface and suffer from the dark/anoxic condition. To investigate the survival of Microcystis and its secretion, a series of experiments were conducted with Microcystis in different growth period. The results suggested that Microcystis could survive for at least 6days under the dark/anoxic condition. Meanwhile, Dissolved organic carbon (DOC) secreted by Microcystis reached up to 1.86mg C mg/Chl a. The Microcystis in 55d group could survive longer than other groups, and 28d group had the maximum quantity of secreted DOC. Our study suggested that Microcystis could survive for several days under the dark/anoxic condition, and could secrete DOC during this period. These results were related to the growth period of Microcystis.

Key words： Microcystis survival dark/anoxic condition organic carbon
