Abstract: Twenty-seven endophytic bacteria were isolated from the roots, rhizome, stems and leaves of moso bamboo by means of grinding separation.A preliminary determination on the diversity of the strains was made based on their phenotypic characteristics as well as the molecular classification using partial 16 SrDNA sequences.The results showed that the isolated bacteria could be classified into 14 genera and 18 species, with Arthrobacter, Bacillus, Ochrobactrumand Staphylococcus being the most predominant.
