Disclosed are transformed cells comprising one or more genetic modifications that affect the lipid content of the cell, e.g., by increasing the concentration of oleic acid in the cell relative to an unmodified cell of the same type. Also disclosed are methods for modifying the lipid content of a cell by increasing the activity of one or more proteins in the cell and/or by decreasing the activity of one or more proteins in the same cell.

The present invention provides for a method to increase the free lipoic acid production in an isolated genetically engineered bacteria or yeast cell. The method involves culturing in a cysteine supplemented culture medium the engineered bacteria or yeast that is transformed with a recombinant expression vector encoding polynucleotide molecules that results in the overexpression of the following genes that are linked to at least one promoter: (1) substrate protein (e.g. Gcv3p); (2) octanoyltransferase or lipoyl synthase; (3) cofactor S-adenosyl methionine synthase; and (4) lipoamidase. The invention also relates to the engineered bacteria or yeast cell thereof.
