Schizochytrium (Schizochytrium sp.) Method and then produced variants of the mutation induction of

摘要

New Schizochytrium (Schizochytrium) variants are provided . In particular , new Schizochytrium (Schizochytrium) mutant has an increased DHA content and / or properties of the growth rate , and increased DHA content and / or DHA production method having a growth rate is provided . Method for producing a novel Schizochytrium (Schizochytrium) mutant strain of the present invention is also provided , the method includes causing Schizochytrium the (Schizochytrium) strain induced mutant derived strains exposed to ultraviolet radiation , untreated the selection of the strains obtained by UV mutagenesis of strain having values growth rate and increased DHA content was improved compared with the Schizochytrium (Schizochytrium) Ltd. , acetyl- coenzyme a, which is a key enzyme in fat synthesis and a be performed under selective pressure by carboxylase inhibitors ( such as quizalofop ) .
