WebImportance of the Melting Point of Rubber Chemicals. In rubber manufacture, different chemical substances are added to the polymer mass. Some of these are effective in production, for example vulcanization accelerators, while others play an important role in the finished product, e.g. antioxidants. WebA water soluble exopolysaccharide was obtained from Lactobacillus reuteri SK24.003 and its rheological and structural properties were investigated. The polysaccharide yield reached around 40.8g/L for 48h of fermentation. The purified exopolysaccharide was an α-d-glucan with the molecular weight of 2.50×10(7)g/mol.
