DNA sequence information for the small-subunit rRNA gene (16S rDNA) obtained from cyanobacterial cultures was used to investigate the presence of cyanobacteria and their abundance in natural habitats. Eight planktonic communities developing in lakes characterized by relatively low algal biomass (mesotrophic) and in lakes with correspondingly high biomass(More)
Eighty-seven Planktothrix (Anagnostidis and Komàrek 1988) strains isolated from 13 lakes in Scandinavia and Finland between 1964 and 2007 were screened for oligopeptides. Forty-six individual compounds were detected in total, belonging to the structural classes anabaenopeptins (six variants), aeruginosins (six variants), cyanopeptolins (21 variants),(More)
