Table 1.

Peptides identified in Nodularia spumigena from the Baltic Sea, Lake Iznik in Turkey and coastal water bodies of Southern Australia. Peptides detected only in bloom sample from the Baltic Sea are marked with asterix (*). AP = anabaenopeptin, NP = nodulapeptin. Black circle—relative peak intensity (i) over 1.7 × 105 counts in time-of-flight mass spectra (TOF MS), bigger empty circles—1.0 × 104 < i < 1.7 × 105 counts in TOF MS, smaller empty circles—ions of the lowest intensity.
