Abstract

Natural products may be a result from the interaction among different organisms. Recent studies with bacterial symbionts have demonstrated that these microorganims can be the real producers of compounds isolated from the symbionts macroorganisms. These researches also have shown that natural products can act as regulators of complex ecological interactions. In fact, the existent literature about the chemical ecology involved in the symbiosis between microorganisms and social insects show that some microorganisms are able to produce antimicrobial compounds that inhibit the growth of insect pathogens. For chemists this research area may lead to the discovery of new molecules, new biosynthetic pathways and an understanding of biological/ecological functions mediated by these compounds. This project proposes the original study of symbiont microorganisms associated with two social insects: the leaf cutter ant Atta sexdens rubropilosa and the stingless bee Scaptotrigona depilis. The symbiont microorganisms will be isolated from the insects and their nests, and the respective microbial natural products will be isolated and identified. Moreover, efforts will be done to understand the natural products' functions involved in the insect nest protection, by carrying out antimicrobial assays against entomopathogenic microorganisms and utilization of modern methods of mass spectrometry. This is a multidisciplinary proposal; therefore a research team with different expertise is involved for the reachment of the goals. (AU)
