Isolation, characterization, identification and antimicrobial screening of
endophytic bacteria from purwoceng�s roots (Pimpinella pruatjan Molk.) has
been carried out. Isolation of endophytic bacteria was conducted using slices of
the root segments. The characterization of endophytic bacteria was conducted
based on morphological, biochemical and molecular characters. Morphological
characters can be seen through the form of colonies, cell shape, edges, elevation
and color of the colony. Biochemical characters were performed by carbohydrate
fermentation, catalase, starch hydrolysis, H2S production, nitrate reduction and
oxidase test. Molecular character based on 16S rRNA gene. Bacterial genomic
DNA obtained was amplified by PCR using specific primers for the 16S rRNA
gene and further characterized by amplified rDNA restriction analysis method
(ARDRA) using restriction enzymes AluI, RsaI, HaeIII and HinfI. Antimicrobial
activity of endophytic bacteria using agar block method. A total of 69 colonies of
endophytic bacteria were isolated and only 30 isolates were successfully purified.
Isolates obtained were dominated by Gram-negative bacteria (70%). The results of
morphological and biochemical characters showed the diversity of endophytic
bacteria isolates. Thrity isolates of endophytic bacteria were identified as
Acidomonas, Amphibacillus, Arsenophonus, Bacillus, Brocothrix, Budvicia,
Cardiobacterium, Cellulomonas, Erwinia, Pantoea, Pediococcus, Plesiomonas
