If colonized pollen grains are transferred to a suitable agar medium containing sea salts, yeast extract and sugar, thalli will grow on the agar surface and may be induced to release zoospores by mounting them in water.
•Thraustochytrids can be stored in pollen grain suspensions or on agar overlaid with sea water.
•They also possess the ability to survive in a dry state at room temperature for a year or longer.
