As an important fruit crop,banana requires large amounts of chemical fertilizers which are costly and can be hazardous to the environments when are used excessively,and the industry is seriously affected by the vascular wilt disease known as Fusarium wilt（Fusarium oxysporum *** race 4, FOC4）.PGPR are important in achieving a sustainable agricultural system,can play a vital role as substitution to commercially available fertilizer in crop production,reduction of environmental problem and suppression of the banana Fusarium-wilt disease to some *** on strong antagonistic activity against *** on the plate dual-culture test,ability to promote growth and suppress banana fusarium wilt disease effectively,some PGPR strains were isolated and selected from the rhizosphere soil of health banana in *** phylogeny of these strains was scientifically analyzed,and the taxonomic positions of them were identified using morphological and chemo-taxonomic characteristics together with 16S rDNA gene phylogenetic ***,these strains are affiliated to Bacillus spp. Several experiments were conducted to evaluate the effects of strain PAB-1 inoculation on growth, nutrient and bio-control of tissue-cultured banana plantlets under greenhouse *** results indicated that a remarkable increase in root properties,namely length（41.5%） and biomass（65.5%） were recorded due to the strain inoculation,beside a higher shoot growth,namely the plant height （18.5%）,pseudo-stem diameter（17.0%） and shoot biomass（16.8%）;The growth attributes namely,consequently the total biomass（24.8%） were also increased due to PAB-1 inoculation
