摘　　要：植物的内生菌与植物生长健康及其功效性成分产生具有一定的相关性。以分离自我国西沙群岛野生诺尼成熟果实的内生细菌菌株NG14为对象,利用形态学观察,生理生化特征鉴定及系统发育学分析,对其菌种的分类地位进行研究,将其鉴定为多黏类芽孢杆菌(Paenibacillus polymyxa);并通过选择多种植物及人体病原菌作为生防对象进行拮抗试验,发现了该菌株具有广谱且良好的拮抗病原菌活性。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.
