Alert system for cyanobacterial bloom and its improvement with molecular techniques

摘要

@@Chlorophyll a concentration and cyanobacterial cell densit y are regularly employed as dual criteria for determinations of the alert level for cyanobacterial bloom.However, the determination of cyanobacterial cell counts is notoriously difficult,and is unduly dependent on individual variation and trained skill.Phycocyanin has been shown to exhibit a strong correlation wit h a variety of bloom-related factors.This may allow for the current alert system criteria to be replaced by a three-stage alert system based on phycocyanin concentrations of 0.1,30,and 700 μg/L.
