초록

In order to understand the Heterosigma akashiwo (Raphidophyceae) bloom, we investigatedthe cell division pattern of its strains under various physicochemical conditions from threedifferent origin. Among the three tested strains, HYM06HA and NFHTS-AK-1, are belong toSouth Korea and CCMP452 strain was from USA. Interestingly among three strains, HYM06HAwas established from the cyst in Korea. Our study results showed that these three strains wereindistinguishable under various salinity and iron (Fe) conditions. All strains were survived at 10to 40 psu and the growth patterns under different iron (Fe) concentrations were observed to besimilar. The growth patterns under different N:P ratios and selenium (Se) concentrations led toclassification of strains into Korean and USA strain. Briefly these results indicated that thegrowth pattern from different strains of H. akashiwo could be dominant using their salinity tolerance. Furthermore nutritional enhancer seemed to be different based on geographical origin.
