New microginins from cyanobacteria of Greek lakes

The first report of microginins isolated from cyanobacteria of Greek lakes was published by Zervou et al. in Chemosphere. As many as 36 new structures of microginins were elucidated with MS/MS techniques. The work was supported by a CYANOCOST STSM grant of Sevasti Zervou (NCSR Demokritos) to Hanna Mazur-Marzec (University of Gdansk).

The paper acknowledges CYANOCOST.

Sponges-Cyanobacteria associations: Global diversity overview and new data from the Eastern Mediterranean

A new paper has been published by Konstantinou et al. (2018) from Cyanolab AUTH, in PlosOne. The authors summarize the global diversity of sponge species hosting cyanobacteria, as well as the diversity of cyanobacterial symbionts and provide a detailed list, along with new data from the Aegean Sea, a previously unexplored eastern ecoregion. The evaluation of the literature along with the new data from the Aegean Sea raised the number of sponge species known for hosting cyanobacteria to 320 and showed that the cyanobacterial diversity reported from sponges is yet underestimated. Highlight of the research is the isolation of nine cyanobacteria strains (only 19 cyanobacteria strains have been isolated to date from sponges). The nine isolated cyanobacteria were found to form novel clades within Synechococcus, Leptolyngbyaceae, Pseudanabaenaceae, and Schizotrichaceae. This is the first report of a Schizotrichaceae cyanobacterium associated with sponges. The results of this research propose the occurrence of new sponge-cyanobacteria associations and new cyanobacteria taxa.
