LC-MS results of MEL-A.

Abstract

(a), Mass spectra of different homologs isolated from the cultivation medium optimized by LC-MS. The units of CH2 or 2H molecular weight differences which are resulted from the different lengths of fat acid chain and the degree of unsaturation present in these compounds. (b), Loss of the erythritol, fatty acids and acetic acid was shown in the MS2 spectra.</p
