The present invention relates to a novel mutant strain of yeast, particularly a strain of Yarrowia lipolytica, which is capable of accumulating a large quantity of lipids. Said strain is deficient in the beta-oxidation of fatty acids and overexpresses the GPD1 gene. Preferably, the mutant strains, which do not express the GUT2 gene and which are deficient for the beta-oxidation of fatty acids, do not express the POX2 to POX5 genes, very preferably the POX2 to 6 genes. The invention also relates to a method for obtaining the strains of yeast according to the invention and to the use of said strains in the production of lipids. |
