Increasing lipid production and optimizing lipid composition
Disclosed are nucleotide sequences and corresponding amino acid sequences of Arxula adeninivorans genes that can be utilized to manipulate the lipid content and/or composition of a cell. Methods and compositions for utilizing this information are disclosed to increase the lipid content or modify the lipid composition of a cell by either increasing or decreasing the activity of certain genetic targets.
