The organic extract obtained of the stem of Tovomita sp. did it present significant antibacterial activity against Staphylococcus aureus (CIM = 460 µg/mL and CBM = 490 µg/mL), Enterococcus faecalis (CIM = 500 µg/mL and CBM = 540 µg/mL) and Pseudomonas aeruginosa (CIM = 300 µg/mL and CBM = 400 µg/mL). The obtained fractions of the organic extract present antibacterial activity against E. faecalis (CIM F1 = 570 µg/mL and CBM F1 = 840 µg/mL; CIM F2 = 480 µg/mL and CBM F2 = 720 µg/mL, respectively) and against P. aeruginosa (CIM F1 = 310 µg/mL and CBM F1 = 570 µg/mL; CIM F2 = 310 µg/mL and CBM F2 = 460 µg/mL, respectively).
