Cyanobakterier. I Östersjön finns Nodularia spumigena, en fintrådig cy-. Fortsatt övergödning av Östersjön tillsammans med allt tunnare ozonskikt gynnar den giftiga cyanobakterien Nodularia spumigena – som  av G Bluhm — Bland cyanobakterier i Östersjön är särskilt Nodularia spumigena, på svenska kallad katthårsalg, uppmärksammad när det gäller toxinproduktion. Nodularia  Avhandlingen visar att högre temperatur och lägre salthalt gynnar trådformiga cyanobakterier som katthårsalgen, Nodularia spumigena. Figur 1 Nodularia spumigena. Page 6. Page 7.

Semi-continuous monocultures of N. spumigena Mertens were established. Regnum: Bacteria • Phylum: Cyanobacteria • Classis: Cyanophyceae • Ordo: Nostocales • Familia: Nostocaceae • Genus: Nodularia • Species: Nodularia spumigena Mertens ex Bornet & Flahault Vernacular names [ edit wikidata 'Nodularia spumigena' ] Assignment to the species Nodularia spumigena is preliminary. Comments of the depositor: "Nodularia is a diazotrophic filamentous cyanobacterium. Nodularia spumigena is a toxic, filamentous cyanobacterium occurring in brackish waters worldwide, yet forms extensive recurrent blooms in the Baltic Sea. N. spumigena produces several classes of non-ribosomal peptides (NRPs) that are active against several key metabolic enzymes. Previously, strains from geographically distant regions showed distinct NRP metabolic profiles.

The production of aeruginosins by N. spumigena was revealed in Assignment to the species Nodularia spumigena is preliminary. Comments of the depositor: "Nodularia is a diazotrophic filamentous cyanobacterium. Nodularia spumigena is a nitrogen-fixing cyanobacterium that forms toxic blooms in the Baltic Sea each summer and the availability of phosphorous is an important factor limiting the formation of We investigated the effects of addition of dissolved organic matter (DOM) on the growth and chemical composition of Nodularia spumigena cells under conditions of P or N deficiency.

Produces a peptide, hepatotoxin, which can kill domestic and wild animals that drink from the shores of eutrophic ponds, lakes and reservoirs.

The nodularin-producing Nodularia spumigena strain UHCC 0039 (hereafter Nodularia UHCC 0039) belongs to the University of Helsinki culture collection (HAMBI, UHCC). Nodularia UHCC 0039 (former name Nodularia spumigena AV1) was isolated from the open Gulf of Finland (Sivonen et al., 1989).
