Isolasi dan Identifikasi Bakteri Endofit pada Akar Tanaman Bawang Dayak (Eleutherine palmifolia L.)

Abstract

The objective of this research to determine the characteristics of endophytics bacteri in Eleutherine palmifolia root visually and microscopically. This research was conducted in 3 steps, started from media preparation, isolation and characterization. The data obtained were then analysed descriptively, namely providing an explanation or description of the types of endophtyic bacteria found on the roots of Eleutherine palmifolia. As many as 3 bacteria isolates obtained from Eleutherine palmifolia root which named AB1, AB2 and AB3. The coloration results show AB1 and AB2 in the form of bacilli and gram positive while AB3 is in the form of gra negative round. Variations in biochemical properties are shown by AB1, AB2 and AB3. Based on the morphological and biochemical charasterictics of endophytics bacteria isolates are thought to originate from Bacillus and Nitrosococcus.
