Isolasi dan Karakteristik Bakteri Endofit pada Akar Pepaya (Carica papaya L)

Abstract

Endophytic bacteria are microorganisms that live entirely or partly in plant tissue (roots, steam, leaves and flower). The purpose of this study was to determine the characteristics of endophytic bacteria in papaya roots (Carica papaya L) macroscopically and microscopically. This research used descriptive method, that was conducted in three stages, started from media preparations, isolation and characterization. The results determined two isolates of endophytic bacteria, those were coded AP1 and AP2. Gram staining show that the two isolates of Bacillus endophytic bacteria were gram positive purple. It was concluded that the morphological characteristics and biochemical test of endophytic bacterial isolates suspected to genus Bacilllus.
