Abstract


Background
Currently, cyanobacterial diversity is examined using a polyphasic approach by assessing morphological and molecular data (Kom\árek 2015). However, the comparison of morphological and genetic data is sometimes hindered by the lack of cultures of several cyanobacterial morphospecies and inadequate morphological data of sequenced strains (Rajaniemi et al. 2005). Furthermore, in order to evaluate the phenotypic plasticity within defined taxa, the variability observed in cultures has to be compared to the range in natural variation (Kom\árek and Mare\š 2012). Thus, new tools are needed to aggregate, link and process data in a meaningful way, in order to properly study and understand cyanodiversity.

New information
An online database on cyanobacteria has been created, namely the Cyanobacteria culture collection (CCC) ( http://cyanobacteria.myspecies.info/) using as case studies cyano- bacterial strains isolated from lakes of Greece, which are part of the AUTH culture collection (School of Biology, Aristotle University of Thessaloniki). The database hosts, for the first time, information and data such as morphology/morphometry, biogeography, phylogeny, microphotographs, distribution maps, toxicology and biochemical traits of the strains. All this data are structured managed, and presented online and are publicly accessible with a recently developed tool, namely \“Scratchpads\”, a taxon-centric virtual research environment allowing browsing the taxonomic classification and retrieving various kinds of relevant information for each taxon.

Cyanobacterial harmful algal blooms (or\ CyanoHABs) represent one of the most conspicuous\ waterborne microbial hazards. The characterization of\ the bloom communities remains problematic because\ the cyanobacterial taxonomy of certain genera has not\ yet been resolved. In this study, 29 planktic and benthic\ cyanobacterial strains were isolated from freshwaters\ located in Greece. The strains were assigned to the genera\ Chroococcus, Microcystis, Synechococcus, Jaaginema,\ Limnothrix, Pseudanabaena, Anabaena, and Calothrix\ and screened for the production of the cyanotoxins\ microcystins (MCs), cylindrospermopsins (CYNs), and\ saxitoxins (STXs) using molecular (PCR amplification of\ seven genes implicated in cyanotoxin biosynthesis) and\ immunological (ELISA) methods. This study presents,\ for the first time, a cyanobacteria culture collection\ from Greece, thus providing missing study material for\ the understanding of bloom formation and cyanotoxin\ production in the Mediterranean and for the polyphasic\ characterization of important components of the\ phytoplankton. The combined use of molecular and\ immunochemical methods allowed the identification of\ MC producing strains, but further data are needed for CYN and\ STX-producing cyanobacteria. The high percentage\ of MC-producing Microcystis strains in the urban Lakes\ Kastoria and Pamvotis, frequently used for agriculture\ irrigation, fishing and recreation, highlights the potential\ risk for human health.
