Quantitative real time PCR for determination of microcystin synthetase E copy numbers for microcystis and Anabaena in lakes

Article Abstract:

The microcystin producing genera are identified and the copy numbers of microcystin synthetase gene E (mycE) in Lake Tuusulanjarvi and Lake Hiidenvesi in Finland by quantitative real time PCR are determined. The findings stated that the main microcystin producer in Lake Tuusulanjarvi was microcystis spp and Lake Hiidenvesi seemed to contain both nontoxic and toxic Anabaena as well as toxic Microcystis strains.

Effects of phosphate and light on growth of and bioactive peptide production by the cyanobacterium Anabaena strain 90 and its anabaenopeptilide mutant

Article Abstract:

The role of the anabaenopeptilides in Anabaena, wild-type Anabaena strain 90 (WT) and its anabaenopeptilide-deficient mutant (MU) grown at different light intensities and with different phosphate concentrations were investigated. The effects and coeffects of these growth factors on the concentrations of the three classes of peptides and the growth characteristics are evaluated.

Direct evidence for production of microcystins by Anabaena strains from the Baltic Sea

Article Abstract:

Microcystin-producing strains of the genus Anabaena in the open Gulf of Finland are isolated. Lower salinity favors microcystin-producing Anabaena strains.
