How to determine antibacterial activity
WebMay 1, 2024 · The antibacterial activity was carried out in methanol, ethanol, acetone and water extracts against E. coli. The maximum activity was noted in root water extract (35.5 ± 3.53 mm), while the minimum activity was found in seed sample (16 ± 1.41) of water extract. WebBased on this, the objectives of our study include: i) investigation on the pathogenic test of crude extracts of selected endophytic bacterial strains against bacterial strains and plant phytopathogenic fungi; ii) determination on the antifungal activity of strain endophytic bacteria against phytopathogenic fungi. 2.
