Alterations in bacterial and fungal community structures during RS-EX treatment revealed by alterations in phosphatidylethanolamine (PE) molecular species composition.

Changes in PE molecular species in A. control and B. RS-EX treated soil samples were measured by Q-TOF mass spectrometry. Markers for bacteria (Bact) and fungi are indicated. Means ± SD are shown (n = 3). Asterisks indicate significant differences to control (t-test; *, p < 0.05; **, p < 0.005). Fatty acids of molecular species are indicated in S2 Table. Arrows indicate increased or decreased amounts of bacterial or fungal molecular species of PE after RS-EX application.
