Gluconobacter strains with exopolysaccharide-producing ability were isolated from the fermentation broth of strawberry. These strains were identified by physiological, biochemical and molecular methods. Meanwhile, the phylogenetic trees were conducted by Neighbor-Joining and Maximum-Parsimony method to determine strain homology and species level. Two high-yield strains were identified as Gluconobacter kondonii, Gluconobacter frateurii naming G. kondonii PFY-7 and G. frateurii PFY-8, respectively. Their exopolysaccharides (EPS) production were (22.93±0.61) g/L and (23.81±0.51) g/L, respectively.
