Abstract
Provided is a microorganism having high sophorolipid production capability. Disclosed is a sophorolipid-producing yeast mutant strain, in which a polypeptide consisting of the amino acid sequence set forth in SEQ ID NO:2 or an amino acid sequence having at least 90% identity therewith, has been deleted or deactivated.
Claims7
A sophorolipid-producing yeast mutant strain, in which a gene encoding a polypeptide consisting of the amino acid sequence of SEQ ID NO:2 has been deleted, wherein the sophorolipid-producing yeast is a microorganism of the genus Starmerella.
A method for producing a sophorolipid-producing mutant yeast strain, the method comprising deleting a gene encoding a polypeptide consisting of the amino acid sequence of SEQ ID NO:2 in the sophorolipid-producing yeast strain wherein the sophorolipid-producing yeast is a microorganism of the genus Starmerella.
A method for increasing the sophorolipid production capability of a parent sophorolipid-producing yeast strain, the method comprising deleting a gene encoding a polypeptide consisting of the amino acid sequence of SEQ ID NO:2 in the parent sophorolipid-producing yeast strain, thereby producing a mutant strain,
- wherein the sophorolipid production capability of the mutant strain is greater than that of the parent strain and wherein the sophorolipid-producing yeast strain is a microorganism of the genus Starmerella.
