Abstract

An endophytic bacterium isolated from banana G-9 (AAA genotype) leaves exhibited strong antagonistic activity against Mycosphaerella musicola. The isolate was identified as Pantoea ananatis 4G-9 by 16S rRNA sequence analysis. Secondary metabolite obtained from P. ananatis 4G-9 was found to have antifungal activity. The active compound was purified from crude extract using column chromatography. Purity of the active compound was assessed using high-performance liquid chromatography. Spectral analysis of compound using infrared, mass spectrometry and nuclear magnetic resonance indicated that the compound structure is an indole derivative. The compound showed strong and dose-dependent antifungal activity against M. musicola. This is the first report on P. ananatis isolated as an endophyte from banana leaves and its antifungal activity against M. musicola.
