ABSTRACT
Endophytic microorganisms are relatively unstudied as potential sources of novel natural products for medical and commercial exploitation. The aim of this work was to investigate some Brazilian tropical savannah trees Cassia leptophylla and Prunus spp. in order to isolate the endophytic microorganisms associated with these plants. The samples were disinfected to eliminate the epiphytic population. Colonies were diluted and displayed as drops in media and growing colonies were inactivated. Staphylococcus coagulase-positive strain was used as indicator microorganism and subjected to the antibioses test. Data showed that the microorganisms isolated from Cassia leptophylla had no inhibition against Staphylococcus. On the other hand, microorganisms isolated from Prunus spp. leaves showed antibacterial activity and inhibited Staphylococcus when cultivated in peptone agar as well as in yeast extract agar. Investigation proceeds in order to classify the isolated microorganisms presenting bioactive substance and exploit the potential of the compounds produced to inhibit the indicator bacteria. Other bioactive properties will be investigated.
