Abstract:   (1108 Views)
This study aimed at investigating the antibacterial effects of extracts from leaf, fruit, and stem of Solanum nigrum on fish pathogenic bacteria. The extraction process was done using the rotary device. The leaf methanol extract and the fruit acetone extract (MIC and MBC of 25 and 12.5 ppm, respectively) showed stronger antibacterial properties. The Streptococcus iniae were the most resistant bacteria against case studies. The Aeromonas hydrophila has been found to be the most resistant bacteria in the fruit methanol and hexane extract. The stem and leaf acetone extracts showed the maximum diameter of the zones of bacterial growth inhibition on Yersinia ruckeri and Aeromonas hydrophila (concentration = 50 ppm) bacteria respectively. Furthermore, the minimum diameter of the zones of bacterial growth inhibition belonged to the leaf hexane extract on Yersinia ruckeri bacteria (concentration = 25 ppm). That using the leaf methanol extract and fruit acetone extract of Solanum nigrum is effective in treating bacterial diseases of the aquaculture.
