The invention relates to a method for constructing a cryptococcus albidus engineering bacterial strain for producing oleic acid in high yield, and provides a yeast engineering bacterial strain for producing oleic acid in high yield. A vector uses pCAMBIA2300 as a basic framework, contains aleurites montana VeSAD genes, and can change an oil producing yeast fatty acid component so as to improve the oleic acid content. The method comprises the following steps of: (1) acquisition of a full-length sequence of a cDNA coding area of the enzyme cutting site-containing aleurites montana VeSAD gene; (2) construction of a VeSAD positive expression vector; (3) acquisition of a recombinant agrobacterium strain; and (4) acquisition of the cryptococcus albidus engineering bacterial strain. The method has the advantages that: the VeSAD genes separated from total RNA of aleurites montana seeds are constructed on the yeast expression vector pCAMBIA2300, and the VeSAD genes are guided into the cryptococcus albidus by adopting an agrobacterium-mediated method so that a synthetic gene of vegetable fatty acid is efficiently expressed in the yeast, the oil yield of the cryptococcus albidus is increased, and particularly the oleic acid content of the grease is improved.
