Evaluation of a Method for Long-Term Cryopreservation of Fungal Strains.

The conservation of microorganisms is essential for their in-depth study. However, today's most widely used conservation methods, based on the use of distilled water, soil, oils, or silica, do not guarantee the stability of fungal cells, especially dermatophytes. This problem led us to evaluate the conservation capacity of a cryogenic vials system containing glass beads covered in a cryopreservant hypertonic solution as an alternative method of storage of fungal cells at -80°C.
