Table 3.
The content of free and total DAB (µg/g DW) in ten strains of cyanobacteria. When more than one discrete sample was screened (different medium of culture or days of growth), the minimum and the maximum concentrations are reported.
| Cyanobacterial Strain | Free DAB (µg/g DW) | Total DAB (µg/g DW) |
|---|---|---|
| Leptolyngbya PCC 73110 a | <LOD–2.69 | 1.01–1.57 |
| Nostoc CCMP 2511/ CMMED01 a | <LOD–2.27 | 0.82–12.48 |
| Microcystis PCC 7806 a | <LOD | <LOD |
| Nostoc PCC 7120 a | <LOD | * |
| Nostoc PCC 7107 a | 2.12–7.2 | * |
| Symploca PCC 8002 a | 0.3 | 0.43 |
| Synechocystis sp.PCC 6803 | <LOD | <LOD |
| Synechococcus elongatus CCAP1479/1B | 0.23–2.71 | 0.4–3.52 |
| Calothrix crustacea CCAP1410/9 | 0.6–0.92 | 6.95–14.53 |
| Nostoc endophytum CCAP1453/14 | 0.34–0.55 | 6.78–7.52 |
* Not analyzed for total DAB; <LOD, a peak corresponding to the transition 119 > 102 was detected at a retention time close to D5DAB, but was not quantifiable (<0.225 µg/g); a strain reported to be a BMAA producer.
