鼠李糖

With regard to different genera, the inhibitory effect might be related to the appendant structure of surface, inner composition and individual size of dinoflagellate cells, and to the same genus, it was related to the fatty acid composition, especially to the content of polyunsaturated fatty acids of the biological membranes of the dinoflagellates, namely, the growth inhibitory effect of rhamnolipid on the dinoflagellates increased with the decreasing of the PUFAs of dinoflagellates.

对不同属的甲藻，这种抑制作用可能与藻细胞本身表面的附属物、内部物质组成及个体大小有关；而对于同一属的甲藻则与各甲藻的生物膜脂肪酸组成尤其是其多不饱和脂肪酸的含量有关，即甲藻的多不饱和脂肪酸含量越低，鼠李糖脂对藻细胞生长的抑制作用越明显，反之亦然。
