Preservation of Malassezia pachydermatis using skimmed milk as cryoprotective agent.

This study evaluated the effect of skimmed milk as a cryoprotectant for the maintenance and long-term preservation of 70 Malassezia pachydermatis strains. An initial suspension of each strain was prepared in sterile distilled water with skimmed milk. The most effective method was cryopreservation that ensured 100% viability for 2years.
