Abstract
An exopolysaccharide (EPS) producing strain, ZW3, was isolated from Tibet kefir grain and was identified as Lactobacillus kefiranofaciens. FT-IR spectroscopy revealed the presence of carboxyl, hydroxyl, and amide groups, which correspond to a typical heteropolymeric polysaccharide. The GC analysis of ZW3 EPS revealed that it was glucogalactan in nature. Exopolymer showed similar flocculation stability like xanthan gum but better than guar gum with a melting point of 93.38 °C which is lower than xanthan gum (153.4 °C) and guar gum (490.11 °C). Compared with other commercially available hydrocolloids like xanthan gum, guar gum and locust gum ZW3 EPS showed much better emulsifying capability.
