Acetic acid (3% vol/vol) consumption (low strength) and lipid production by using Y. lipolytica in semicontinuous mode. A hollow fiber module was used to recycle cells and maintain constant volume. The time courses show a lipid titer of 46 g/L with an overall productivity of 0.27 g⋅L⁻¹⋅h⁻¹ and lipid content of 59%. SDs from triplicate runs are presented.
