The growth, lipid content, and fatty acid composition of Aurantiochytrium sp. strain mh0186 at different temperatures were investigated. Strain mh0186 grew well at 15-30°C, but weakly at 10°C. The biomass at 15-30°C was significantly higher than at 10 and 35°C, and the total lipid at 15-35°C was significantly higher than that at 10°C. The amount of DHA in the total fatty acid was highest at 10°C and decreased in response to temperature increase. The content of DHA (mg/g-dry cell weight) at 15-30°C were significantly higher than those at 35°C and those at 15-25°C were significantly higher than those at 10 and 35°C. The DHA yield at 15-35°C was significantly higher than those at 10 and 35°C. Unsaturation of fatty acid was regulated by temperature and was enhanced in response to temperature decrease. The ratio of DHA to DPA varied at different temperatures.
