Culture Collection of Baltic Algae (CCBA), founded in the 1980s, has a university status. It puts emphasis on Baltic cyanobacteria, green algae and diatoms. Now it contains about forty original algal strains isolated from the coastal waters of the Southern Baltic. Curator of CCBA is Dr. Adam Latała, e-mail address: oceal@univ.gda.pl. The complete list of original Baltic strains and strains acquired from other collections, which are maintained in CCBA, will appear on the web site: http://www.ocean.univ.gda.pl/∼ccba/.At present there is no significant algal culture collection in Poland. Therefore, an enrichment of CCBA with new algal strains isolated from different inland waters in Poland is planned. Special attention would be paid to algal species threatened by extinction, rare, endemic, toxic, harmful or typical of our region.The growth of Baltic strains has been characterized by factorial experiment approach. The effects of salinity, light and temperature, as well as their interaction have been determined. The brackishwater character showed: Chlorella vulgaris, Oocystis submarina, O. parva, Stichococcus bacillaris, Cyclotella meneghiniana, Skeletonema costatum, and Nodularia spumigena, cyanobacterium Phormidium amphibium was the marine strain and green algae from the genus Scenedesmus and Monoraphidium were freshwater strains. The growth of the above strains was strongly affected by light and temperature interaction. This effect was especially distinct in diatoms. However, the influence on the light alone was not so well-marked.For six strains: Monoraphidium convolutum, Amphora coffeaeformis, Entomoneis punctulata, Haslea spicula, Nitzschia thermaloides and the second strain of Skeletonema costatum only influence of salinity was investigated. It occurred that green alga was a typically freshwater species, Skeletonema costatum showed marine character, however the remaining strains were brackishwater.
