Supplementary Material

Highly purified series-2 glycolipid prepared from the chloroform/methanol extract of C. matruchotii cultured in the presence of Tween 80 was analyzed by MALDI mass spectrometry. From the resulting spectrum (Figure S1), MNa+ peaks at m/z 1111 and 1331 were lifted for tendem mass spectrometry (MS-MS).

Figure S1: MALDI mass spectrum of series-2 glycolipid from C. matruchotii grown in the presence of Tween 80. This spectrum shows the structrual series of the major series-2B peaks at m/z 1067-1859 and minor series-2A peaks at m/z 1259-1567.
