Antivibrio activity of Homalomena sp cultures

Abstract

Homalomena species belongs to Araceae family. It is an aquatic plant that can be found in the humid climate of South America and Tropical Asia. The goal of this work was to test the antivibrio activity of the methanol extracts of Homalomena sp. cultures at three different cultivation time (30, 50 and 70 day). The whole part of plant materials (leaves, petioles and rhizomes) was investigated for its antibacterial activities against Vibrio vulnifucus, V.alginolyticus and V.parahaemolyticus. The antivibrio bacteria activity of the methanolic crude extracts were tested by the disc diffusion technique. Results show that no activity against the tested bacteria. V. vulnifucus, V.alginolyticus and V.parahaemolyticus were resistance to methanol extracts of Homalomena sp. cultures. Methanol extracts of plant with difference cultivation time did not gave any influence on antivibrio activity. Further study need to be done to determine the antibacterial activity of Homalomena sp. cultures against other bacteria.
