Abstract

Root-associating bacteria of the nipa palm (<I>Nypa fruticans</I>), preferring brackish-water affected mud in Sarawak, Malaysia, were investigated. In a comparison of rhizobacterial microbiota between the nipa and the sago (<I>Metroxylon sagu</I>) palm, it was found that the nipa palm possessed a group of <I>Burkholderia vietnamiensis</I> as its main active nitrogen-fixing endophytic bacterium. Acetylene reduction by the various isolates of <I>B. vietnamiensis</I> was constant (44 to 68 nmol h<SUP>−1</SUP> in ethylene production rate) in soft gel medium containing 0.2% sucrose as sole carbon source, and the bacterium also showed motility and biofilm-forming capacity. This is the first report of endophytic nitrogen-fixing bacteria from nipa palm.
