Unformatted text preview: rbent assay [ELISA]) were highly correlated in the littoral (r 0.93, P < 0.001) and the pelagic station
(r 0.87, P < 0.001) in 2006. In contrast to the situation in 2006, a cyanobacterial bloom occurred only in late
summer-early fall of 2007, reaching only 3 102 mcyDKS copies ml 1, while the microcystin concentration was
barely detectable. The Q-PCR method allowed the detection of microcystin-producing cyanobacteria when
toxins and toxigenic cyanobacterial abundance were still below the limit of detection by high-pressure liquid
chromatography (HPLC) and microscopy. Toxin gene copy numbers grew exponentially at a steady rate over
a period of 7 weeks. Onshore winds selected for cells with a higher cell quota of microcystin. This technique
could be an effective approach for the routine monitoring of the most at-risk water bodies.
the fall. To date, ﬁve species known to produce toxins based on
the literature (2) have been identiﬁed in the lake, including
species of Microcystis and Anabaen...
