Figure 5. Dynamic production of MC-LR from Microcystis aeruginosa.

Figure 5.

(A) Schematic illustration of production of MC-LR by cells in Microcystis aeruginosa culture. (B) Optical image of cyanobacterial cells. (C) MC-LR levels produced by toxic cyanobacteria (Microcystis aeruginosa UTEX LB 2385) and the control, non-toxic cyanobacteria (Microcystis aeruginosa UTEX LB 2386) over the course of incubation (0 to 240 hours) tested the SERS immunoassay and compared to the measurements obtained by the commercial ELISA kit. Samples with MC-LR concentrations > 2.0 μg/L were diluted prior to the ELISA measurement, taking the narrow dynamic range of the ELISA kit into account. (D) MC-LR production rate by the toxic cyanobacteria from single cyanobacterial cells, which was measured by dividing the total MC-LR level by the calculated abundance of Microcystis aeruginosa.
