To prove the role of acetic acid bacteria as an additional plant growth promoter, the two strains of Nguyenibacter vanlangensis (TN01LGIT and VTH-AC01), the family Acetobacteraceae, were examined for nitrogen fixing ability, phosphorus and zinc solubilizing capability, phytohormon auxin production, and inducing activity of an expression of encoding the pathogenic-related protein gene. | The traits of the plant growth promoting acetic acid bacterium, Nguyenibacter vanlangensis
