| abstract |
The subject of the present invention is a novel mutant yeast strain, particularly a Yarrowia lipolytica strain, capable of accumulating a large quantity of lipids. The said strain does not express the GUT2 gene. According to one variant, the invention relates to mutant yeast strains, particularly Yarrowia lipolytica strains, which do not express the GUT2 gene and which furthermore do not carry out the ß-oxidation of lipids. Preferably, the mutant strains which do not express the GUT2 gene and which furthermore do not carry out the ß-oxidation of lipids do not express the POX 2 to POX 5 genes, most preferably the POX 1 to 6 genes. The subject of the invention is also a method for producing the strains according to the invention and the use of the said strains in the production of lipids. |
