title: Deployment of the encapsulation-dehydration protocol to cryopreserve polar microalgae held at the Czech Republic Academy of Sciences Institute of Botany.
abstract: Polar isolates of four chlorococcal microalgae originating from the Arctic and Antarctica withstand cryopreservation using encapsulation-dehydration. Viability assessments, which initially used chloroplhyll fluorescence (Kautsky) induction kinetics, revealed that all strains suffered photosynthetic impairment during early post-cryopreservation recovery. This cryoinjury was reversible, as indicated by cell regrowth in three of the four strains. Lack of growth in the fourth isolate was due to contaminating bacteria rather than cryogenic factors.
