Patent ID: 7396672

Claim:
A method for obtaining an isolated or purified culture of a dinoflagellate, said method comprising selecting one or more dinoflagellate cells from a sample, placing said dinoflagellate cell or cells in a growth medium containing mimosine or 3,4-dihydroxypyridine at a concentration of from 0.001 mM to 50 mM, culturing the mixture thus obtained in an incubator until cell multiplication of the dinoflagellate is evident thereby obtaining an enriched culture and, if necessary, transferring the enriched culture to fresh medium containing mimosine or 3,4-dihydroxypyridine at a concentration of from 0.001 mM to 50 mM and repeating the sub-culturing of said enriched culture, until an isolated or purified culture of the dinoflagellate is obtained.
