Species Diversity of Cultivable Bacteria Isolated from the Roots of Cymbidium faberi Rolfe

Certain entophytic bacteria strains were investigated following isolation from the roots of Cymbidium faberi Rolfe in Hubei province,China.An MS medium+ Cymbidium faberi root extract was used in this study.Twentyseven strains were selected based on the morphology of their colonies.According to 16S rRNA gene sequences analysis and comparison with data from the GenBank,they belonged to 14 species of 8 genera,namely Burkholderia phytofirmans,Pseudomonas jessenii,P.cedrina,P.mohnii,P.fragi,P.koreensi,Bacillus megaterium,B.atrophaeus,B.subtilis,Leifsonia shinshuensis,Variovora paradoxus,Erwinia rhapontici,Duganella zoogloeoides, and Acinetobacter lwoffi. Understanding the relationship between these bacteria and Cymbidium faberi is valuable,particularly in relation to the benefits of these bacteria in the cultivation of Cymbidium faberi Rolfe.
