摘要：

Microalgae Tetraselmis subcordiformis and Nannochloropsis oculata were cultured at 15, 20, 25, 30, and 35 degrees C and their properties as potential biofuel resources were examined. The results indicate that T. subcordiformis and N. oculata grew best at 20 degrees C and 25 degrees C and yielded the highest total lipids at 20 degrees C and 30 degrees C, respectively. With increased temperature, neutral lipid and polyunsaturated fatty acids (FAs) decreased while saturated FAs increased, accompanied by increased monounsaturated FAs (MUFAs) in T. subcordiformis and decreased MUFAs in N. oculata; meanwhile, the predicted cetane number of FA methyl esters increased from 45.3 to 47.6 in T. subcordiformis and from 52.3 to 60.3 in N. oculata. Therefore, optimizing culture temperatures is important for improving microalgal biodiesel production.
