In other to produce vinegar using Schizandra chinensis Ballon(omija), acetic acid bacteria(AAB) were selected from several conventional vinegars, and total 30 acetic acid bacterial strains were isolated. Among the isolated strains, a strain was selected from medium containing omija juice which showed the highest productivity of acetic acid. The strain was identified as Acetobacter sp. C5-1b. Optimum conditions for acetic acid production of Acetabacter sp. C5-1b were involved with 30t: of fermentation temperature and shaking culture. The acidity of culture medium was reached to 5.3% after 8 days shaking cultivation at 30℃.
