摘要：

Strains of S. thermophilus grown on partially deproteinized whey produced an exocellular polysaccharide which contained L-rhamnose and D-galactose in thc ratio 1:1.47. Methylation analysis showed the existence of 3 and 6-substituted D-galactose, 2-substituted L-rhamnose and nonreducing terminal D-galactose. A polysaccharide was also obtained from the cell surface after sonication. Molecular weights of both polysaccharides were estimated by gel filtration on HPLC at about 9,000,000 and 1,100,000, respectively. These polysaccharides were different from the previously reported products by S. thermophilus strains and their presence may contribute to the ropy property of yogurt.
