Table 2: Mycelial concentration (mg per g dw ± SE) of MC-LR, BMAA (free and protein-bound) and CYN after exposure of M. hiemalis EH5 to 1000 µg/L for 24 and 48 hours. Values are means ± SE. Significant differences (ANOVA, t-test, p < 0.05) between treatment and control of both sampling dates with no timedependency (p > 0.05) were observed. *ND ‑ not detected.
