Isolation and identification of endophytic microorganisms of Campomanesia adamantium (Cambess) O. Berg (Myrtaceae) and their metabolites
Resumen
Campomanesia adamantium (Cambess.) O. Berg (Myrtaceae) is a shrub used in folk medicine for stomach disorders and urinary tract infections. The aim of this study was isolate and identify endophytic microorganisms from C. adamantium leaves and their metabolites. The botanical material composed of C. adamantium leaves was collected near Bela Vista, Goiás. Four actinobacteria, 10 bacteria and 60 fungi were isolated. Three fungi were able to maintain the feasibility of experimentation in the laboratory: Cercospora zebrina, Agaricales sp, and Passarola daleae. Crude ethyl acetate extract was obtained from strains cultured in Czapek broth, and the produced metabolites were analyzed by electrospray ionization mass spectrometry (ESI MS). 36 metabolites were identified. This work represents the first isolation of endophytic fungi and their metabolites from C. adamantium leaves, opening future perspectives of researches with biotechnological interest in medicine, industry or agriculture.
