摘要: Skeletonema costatum was submitted to two experiments using UV lights and CO2with the purpose of observing changes in lipids profile synthesis polyunsaturated aldehydes (PUA) after cell disruption. When cells receive CO2 supply, it noticed that production PUA significantly lower. The same observed when culture treated with a dose 45.9 kJ·m-2 ultra-violet A/B ray. premise all 2,4-heptadienal compared supply EPA as substrate. As result, rate both treatment applied experiment control. On other hand, subjected ultraviolet radiation showed 68% greater demand utilization These observations suggested consumed before disruption probably exuded surrounding environment sign stress. Changes morphology could be by migration chloroplast nearby wall, where produced, indicating defense strategy.
