1. A method for producing squalene that employs a strain of Aurantiochytrium tsukuba-3 (deposit number: FERM BP-11442), wherein said strain produces at least 10 mass % squalene among the total lipids, and forming colonies that exhibit an orange-to-red color, said method comprising the steps of:
culturing cells of said strain at pH of 4.5-9.0 and 10° C. to 30° C. for 3 to 7 days; harvesting squalene-containing lipids from said cultured cells; and then extracting squalene from said squalene-containing lipids.
