Effectiveness Of Extracted Antibacterial Compound From Hydroid Aglaophenia Cupressina Lamoureoux Against Bacterial Cell Of Escherichia Coli

Pollution by pathogenic microorganisms in food materials is capable of resulting in various diseases and increased resistance against various types of antimicrobial. Therefore new more effective antibiotics are needed to overcome the multi-drug resistant bacteria. This study was aimed to examine the effectiveness of extracted antibacterial compound from hydroid iAglaophenia cupressinai Lamoureoux in inhibiting and killing the iEscherichia colii an organism that frequently pollute food material. This study was an experimental study with the following treatment steps isolation and characterization of compounds from hydroin A. cupressina Lamoureoux by chromatography elucidation of the isolate molecular structure by UV IR and NMR. Two isolates obtained were hexadecanoic acid and Agalo E.Unhas both of them were tested against iE. colii at various concentrations 10 ppm 20 ppm and 30 ppm. The damage to the iE. colii were examined by Electron Microscopic Scanning. Study results indicated that hexadecanoic acid at concentration of 10 ppm and 20 ppm and Aglao E. Unhas at concentration of 10 ppm 20 ppm and 30 ppm was bacteriostatic against E. coli whereas the hexadecanoic acid at concentration of 30 ppm was bactericidal against iE. colii.
