PROBLEM TO BE SOLVED: To provide useful products such as fatty acids utilizing microorganisms of the thraustochytrid species; and usages thereof.SOLUTION: The present invention provides newly isolated strains of the thraustochytrid species, and mutants obtained from the strains by irradiation treatment or the like being rich in docosahexaenoic acid and the like. Based on the strains, the invention also provides cultures, biomasses, extracted microbial oils, and their compositions. Further provided are methods of applying the biomasses, the microbial oils and the compositions to food, feed, cosmetics and pharmaceuticals. 【課題】ヤブレツボカビ種の微生物を利用した脂肪酸等の有用産物の提供ならびにその利用法の提供。【解決手段】ヤブレツボカビ種のあらたに単離された菌株及び該菌体より放射線処理等により得られたドコサヘキサエン酸等を多く含有する変異体。該菌株の培養物、バイオマス、抽出された微生物油、及びそれらの組成物。さらに該培養物、該バイオマス、該微生物油、及び該組成物の食品、飼料、化粧品、並びに医薬への利用法。【選択図】なし
