LC/MS identification of acyl-triHDAG from strain FRIFI. Negative ion ESI/MS showing the [M + Cl]− ions of the lipid emerging at 12.7 to 13.7 min. The structural drawings of carbohydrates are for the illustration of chemical formula, and are based on previous reports that bacterial glycolipids, at least majority of them, contain hexopyrnoses (glucose, galactose and mannose) [16].
