Comparison of HPLC Analysis and a Channel Biosensor in the Detection of PSP Toxin in Natural Alexandrium tamarense Population
Hae-Ok Lee, Byeung-Soo Cheun, Etuo Watanabe, Myung-Soo Han
The PSP (Paralytic Shellfish Poisoining) toxin of natural A. tamarense population collected at Masan (Stn M) and Chilchundo (Stn C) in Chinhae Bay, Korea was determined by the biosensor and HPLC. From these results, it was recognized that a good relationship was shown between toxicity obtained by the biosensor and HPLC, and that the biosenor was simple, powerful and useful system to monitor the changes of very low PSP toxin in natural A. tamarense population. Therefore, the proposed biosensor could be used for monitoring the STX in the toxic phytoplankton and shellfish in near future.
Key words: Alexandrium tamarense, biosensor, HPLC, PSP toxin
