Abstract
Microbes associated with fungus-growing ants represent a poorly explored source of
natural products. In this study, we used mass spectrometry-based dereplication techniques
for identifying a set of secondary metabolites produced during the microbial interaction
between Streptomyces sp. (CB0028) and Escovopsis sp.
(CBAcro424). Both microorganisms were isolated from the nest of the fungus-growing ant
Acromyrmex echinatior. Through MALDI imaging and MS/MS molecular
networking, we annotated the siderophores: desferrioxamine B (
