Identification and Antagonistic Activity of Endophytic Bacterial Strain NG14 Isolated from the Fruits of Paracel Islands Noni(Morinda citrifolia L.)

Abstract

Abstract: Endophytes related with healthy and efficacy component production of plants. In this study，the bacterial strain NG14 isolated from Paracel Islands Noni(Morinda citrifolia L.)fruit. NG14 was identified as Paenibacillus polymyxa by polyphasic taxonomy basing on morphologicial and physiological methods，and 16S rRNA gene phylogenetic analysis. Through the antagonism test，results showed that the strain NG14 had a comprehensive and fine antagonistic activity against pathogens chosen for this research.

Key words: Noni, Endophytes, NG14, Identification, Antagonistic activity
