Proceedings: Preservation of marine and fresh water algae by means of freezing and freeze-drying

Several species of marine and fresh water algae have been isolated from various habitats. Recently they were examined for their viability after freezing and freeze-drying procedures.The addition of suspending agents to algal cultures has resulted in greater viability for most of the green algae, but has shown little effect on the blue-green algae.It is considered that the preservation of algae by means of freezing and freeze-drying procedures are of great benefit as they offer the possibility of long-term preservation of viable collections, especially for patent depository for industrial applications.
