Effect of two kinds of ILs on fatty acid composition of cells. The percentage of loss total lipids (triangle) was extracted from samples of lyophilized cells (200 mg each) with 100 mL chloroform/methanol (2:1, v/v). The extracts were separated by filtration, evaporated, methanolyzed. The fatty acid contents of two kinds of ILs treated cell membrane and untreated cells were determined using GC–MS
