A new Schizochytrium variant strain is provided. In particular, a new Schizochytrium variant strain having properties of increased DHA content and/or improved growth rate, and a method for producing DHA with the same are provided. Also provided is a method for producing the new Schizochytrium variant strain of the invention comprising exposing a Schizochytrium strain to UV radiation to induce a mutagenesis of the strain, and screening the strains obtained by the UV mutagenesis for a strain with improved growth rate and increased DHA content compared with those in a naive Schizochytrium strain under the selection pressure by a inhibitor (such as Quizalofop) of a key enzyme in fat synthesis, acetyl coenzyme A carboxylase. |
