| Abstract: | Two antibiotics,viz.ampicillin(Amp) and neomycin(Nm) were investigated regarding their effects on a toxic dinoflagellate,A.tamarense C101,which was isolated from the South China Sea.The study found that Nm concentration of 1 500 μg/mL retarded the growth rate of the algal cell,while 2 000 μg/mL of Amp stimulated the cells growth though resulting in sloughing-off of part of the cell walls.Analysis of the toxin content of A.tamarense C101 by HPLC indicated that both of the antibiotics decreased the toxin of the algae through inhibition of the activity of toxin-producing or toxin-benefiting bacteria.Otherwise the antibiotics might influenced some enzymes involved in toxin biosynthesis,leading to the decreased toxin producing capacity of A.tamarense C101. |
