Abstract Isochrysis zhangjiangensis is widely used in the marine aquaculture as larval feed, especially for filter feeding cultures, as well as a good candidate for biofuels. However, the optimal cultivation temperature for I. zhangjiangensis is below 30 °C and this stain is seriously affected by high temperature, which causes the limited application during the summer. I. zhangjiangensis IM130005 is a strain generated by atmospheric and room temperature plasmas with relative higher growth rate and lipid production than the wide strain (WT), with the ability to tolerate several hours’ high temperature during the outdoor cultivation. Here, a detailed comparison was performed by continuous monitoring growth, chlorophyll fluorescence and fatty acid profile between IM13005 and WT under a mimic temperature shock to the summer outdoor cultivation. Based on a nearly 20% increase of total fatty acid in IM13005, which was majorly contributed by saturated or monounsaturated FAs in form of neutral lipids, within 5 h under the heat shock, the fatty acids and lipids synthesis variation were postulated as the physiological reason for the high temperature tolerance. |
