Stress resistance of single stock cultures of filamentous green algae from the genus Klebsormidium (Streptophyta) isolated from the polar regions and from Slovakia; Stresova rezistencia jednodruhovych kmenovych kultur vlaknitej zelenej riasy z rodu Klebsormidium (Streptophyta) izolovanych z polarnych oblasti a zo Slovenska

Abstract

Single-fiber stem cultures of green algae of the genus Klebsormidium PC Silva, K. R. Mattox et W.H. Blackwell isolated from the both polar regions and from Slovakia were subjected to the effects of the environmental stress including various options of dessication and freezing. Klebsormidium algae species has a wide ecological amplitude and equally broad biological plasticity that allows it to adapt and survive in adverse environmental conditions. Based on the performed microscopic analyses of algaes after exposure to stressors, the experimental strains were generally the most resistant to the slow and rapid freezing. Exposure of the strains to lyophilization was shown as the most drastic stress factor of all, to who were the most resistant arctic strains 9 LUC, LUC 11, LUC 14 as well as MON 1 strain from Slovakia and LUC strain 8 of Antarctica. The least resistant to environmental stress were two Antarctic strains LUC LUC 4 and 5. However, we can not explain it yet and it will be the subject of the further study. (authors)
