Streptomyces sp. CBMAI 2042 Extracts


ABSTRACT: Ethyl Acetate fraction of Streptomyces sp. CBMAI 2042 was investigated for identifying cyclodepsipeptides using electrospray ionisation tandem mass spectrometry (ESI-MS/MS). Without prior isolation, the structural determination was achieved on the basis of mass fragmentation pattern and comparison with the previously established data. The ESI-MS of the fraction in the positive ion mode gave clusters of singly and doubly charged molecular ion peaks. The ESI-MS spectrum showed peaks for the presence of the cyclodepsipeptides Valinomycin, Montanastatin and at least 5 structural analogues never reported before.
