Effects of light on the microcystin content of Microcystis strain PCC 7806
Article Abstract:
Results show that the cellular microcystin content of Microcystis strain PCC 7806 varies between 34.5 and 81.4 fg per cell, which is positively correlated with growth rate under photosynthetically active radiation-limited growth. Data indicate a positive effect of light on microcystin production during and up to the maximum growth rate with hihger irradiances causing inhibition.

Toxic and nontoxic Microcystis colonies in natural populations can be differentiated on the basis of rRNA gene internal transcribed spacer diversity
Article Abstract:
The genetic distinction of Microcystis colonies depending on the rRNA internal transcribed spacer (ITS) series giving out substantial foundation for the identification of microcystin producers is displayed. The inconsistencies reported for Microcystis identification based on morphology were confirmed by the rRNA ITS sequences.

Determination of oligopeptide diversity within a natural population of Microcystis spp. (Cyanobacteria) by typing single colonies by matrix-assisted laser desorption ionization-time of flight mass spectrometry
Article Abstract:
Researchers found a large number of bioactive peptides in Microcystis spp. including microcystins, anabaenopeptins, microginins, aeruginosins, cyanopeptolins, and many unknown peptides. Different species produced different peptides, which means MALDI-TOF mass spectrometry could be used as a chemotaxonomic tool.
