摘要： Recently, H. pluvialis has been demonstrated to have significant potential for biofuel production. To explore the correlation between total lipid content and other physiological parameters under s tress conditions, the responses of H. pluvialis to high light intensity (HL), nitrogen deprivation (-N), and high light intensity with nitrogen deprivation (HL-N) were investigated. The total lipid content in the control cells was 12.01% dw, whereas that of the cells exposed to HL, -N, and HL-N conditions was 56.92, 46.71, and 46.87% dw, respectively. The fatty acid profile was similar under all conditions, with the main components including palmitic acid, linoleic acid, and linolenic acid. A good correlation was found between individual carotenoid and total lipids, regardless of culture conditions. P hotosynthetic parameters and lipid content were also found to be well-correlated.
