The Fusarium mycotoxins fumonisin B(1) (FB(1)) (1) and B(2) (FB(2)) (2), their hydrolysed analogues HFB(1) (3) and HFB(2) (4) and the recently discovered fumonisin derivatives N-palmitoyl-HFB(1) (5) and N-carboxymethyl-FB(1) (6) were compared for their toxicity in a short term bioassay using brine shrimp (Artemia salina). The brine shrimp were hatched in artificial sea water and exposed to the fumonisins in microwell plates with a mortality endpoint after 48 hours. LC(50) values were calculated after Probit transformation of the resulting data. Of the substances tested, fumonisin B(1) emerged to be the most toxic whereas its N-carboxymethyl analogue was 100-fold less effective. The hydrolysed fumonisins showed a four- to sixfold reduced toxicity compared to FB(1). N-Palmitoyl-HFB(1) had a higher LC(50) value than its precursor HFB(1). The brine shrimp assay proved to be a convenient and rapid system for toxicity assessment of this group of mycotoxins.
