摘要：

The activity of the degradation products of linoleic and Linolenic acids in inhibiting the growth of the green alga Chlorella pyrenoidosa was determined using the paper disk-agar plate method. Although hydroperoxides derived from these acids and aldehyde biodegradation products and other related aldehydes and alcohols showed inhibitory activity, it is concluded from the weakness of the activities that the inhibitory effects of polyunsaturated fatty acids (PUFAs) on Chlorella growth is due mainly to the acids themselves and not their degradation products. The evidence for the possible ecological role of PUFAs as toxic agents against phytoplankton is presented.
