Figure 2. Phospholipids (panels a, b), glycolipids (panels c, d) and carotenoids (panels e, f) of R. erythropolis IBBPo1 cells after 1% organic solvents exposure. The TLC plates were visualized (panels a, c, e) and scanned (panels b, d, f) under a 500 nm visible white light (panels a-d) or under a 254 nm ultraviolet light (panels e, f); bacterial cells cultivated 1 h (lanes 1, 3, 5, 7, 9, 11, 13) and 24 h (lanes 2, 4, 6, 8, 10, 12, 14) in minimal medium; control (lanes 1, 2), cyclohexane (lanes 3, 4), n-hexane (lanes 5, 6), n-decane (lanes 7, 8), toluene (lanes 9, 10), styrene (lanes 11, 12), ethylbenzene (lanes 13, 14). Panels a, b. Phospholipids standards (SL), lysophosphatidylcholine (LPC), phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), phosphatidylinositol (PI), cardiolipin (CL), fatty acids (FA). Panels c, d. Sugars standards (SS), trehalose (T), L-rhamnose (R), trehalolipids (THL1, THL2), fatty acids (FA). Panels e, f. Carotenoids standards (SC), phytoene (Pe), lycopene (Ly or ψ, ψ-carotene), 4-keto-γ-carotene (KγC), chlorobactene (CB or Φ, ψ-carotene), γ-carotene (γC), β-carotene (βC). The phospholipids, glycolipids and carotenoids spots and their corresponding peak have been marked by arrows.
