| Binding and Peroxidative Action of Oxyfluorfen in Sensitive and Tolerant Algal Species  | | | | Abstract
| Peroxidative activity of oxyfluorfen and binding o f this nitrodiphenyl ether to cell fractions was investigated with the susceptible alga Scenedesmus acutus and the resistant alga B um illeriopsis filiform is. A lthough a 10-fold higher concentration o f oxyfluorfen was applied to Bum illeriopsis, the lag phase for initiation o f peroxidative evolution of short-chain hydrocarbons from fatty acids was much longer than found with Scenedesmus. Oxyfluorfen was predominantly recovered after hom ogenization from the pellet which was separated into a lipid and a chloroform /m ethanol insoluble fraction. Parts o f the oxyfluorfen which is present in the insoluble pellet fraction during the lag phase before the onset o f peroxidation can be found in the lipid fraction when measurable peroxidative activities have started. This was observed with Scenedesm us as well as with B um il leriopsis. During peroxidation initiated by oxyfluorfen acyl lipids are degradated as m onitored by the disappearance o f the plastidic sulfolipid. Analysis o f bound fatty acids showed that they are targets for peroxidative reactions in acyl lipids. Destruction o f polyunsaturated fatty acids was higher than for saturated ones. | | | |
