Abstract
Exopolysaccharide (EPS) producing Weissella cibaria CMGDEX3 was isolated from cabbage on sucrose containing De Man, Rogosa and Sharpe (MRS) agar. Dextransucrase activity and dextran yield was found to be 7.1 DSU mlâ1 and 2.4 g dlâ1, respectively. The structural characterization of purified EPS determined by FTIR, 1H and 13C NMR spectroscopy demonstrated that W. cibaria CMGDEX3 synthesized a linear dextran that predominately had α (1â6) glycosidic linkages with only a few (3.4%) α (1â3) linked branches. Molecular mass determination showed that it was a high molecular weight dextran of an average >2,000,000 Da. According to our knowledge this is the first report on isolation of dextran synthesizing Weissella genus from Pakistan.
