Optimum conditions of temperature, salinity and glucose concentration were investigated for squalene production of the strain of Aurantiochytrium sp. 18W-13a, with a high content of squalene. Squalene production by this strain was optimum at 25°C, 25–50% seawater concentration and 2–6% glucose concentration. When this strain was grown in the optimum condition, the squalene content and production of approximately 171mg/g dry weight and 0.9g/L were much higher than that previously reported in thraustochytrids, plants and yeasts, respectively. Therefore, 18W-13a could be used as an alternative source of commercial squalene.
