ELSD (top) and single ion monitoring LCMS traces (middle, bottom) of fraction 3 (2:8 H2O:MeOH) generated from rice fermentations of W. reniformis. Due to differences in tubing length, there is a 4 sec delay between the ELSD and MS detectors. High resolution mass spectra and UV absorbance traces (200–400 nm) are provided confirming the production of melinacidin IV and chetracin B. ‘Denotes possible artifacts due to reverse phase chromatography or presence of analogs.
