Exceptional solvent tolerance in Yarrowia lipolytica is enhanced by sterols

C Walker, S Ryu, CT Trinh - Metabolic engineering, 2019 - Elsevier
Green organic solvents such as ionic liquids (ILs) have versatile use but are inhibitory to
microbes even at low concentrations of 0.5–1.0% (v/v) ILs. We discovered the oleaginous yeast …
