Abstract:
The effects of strain S10 isolated from sediments of Xiamen Western Sea Area on the growth and paralytic shellfish poison (PSP) production of Alexandrium tamarense at different pH and salinities were studied. The results showed that the alga grew well at pH 6-8 and at salinity of 20-34. The toxicity of A. tamarense varied markedly at different pH and salinities: it decreased with increasing pH, while increased with salinity and reached its peak value at the salinity of 30, and then declined. The strain S10 inhibited the growth and the PSP production of A. tamarense at different pH and salinities. It had the best inhibitory function on the growth of A. tamarense at pH 7 and salinity of 34. The best inhibitory function on the PSP production of A. tamarense was at pH 7, but this inhibitory function was not related to salinity.
