The ice nucleation activity of green algae isolated from low-temperature environments
Popis výsledku v původním jazyce
Abstract: The survival of the algae at low temperatures requires many adaptation/acclimatization strategies. The algae from different cold habitats could develop various mechanisms of freezing tolerance and cryoprotective mechanisms. In our study, two groups of algae living in different low-temperature environments were evaluated. The environment of snow algae - melting snow - is characterised by stable temperatures around 0 deg C and water is usually available. On the other hand, the lichen thalli aresubjected to temperature and moisture variation and undergo dehydration-hydration cycles. Ice nucleation activities of two species of snow algae, Chlamydomonas nivalis and Chloromonas nivalis, three lichen fycobiont algae, Trebouxia asymmetrica, Trebouxia erici and Trebouxia glomerata, and one mesophilic alga Chlamydomonas reinhardtii (control) were studied by ice nucleation spectroscopy. Freezing points of 25 droplets of algal suspension and 5 control droplets of DNA-se free water were
