Abstract: Zymomonas mobilis strain 113 "S" produces levan -an extracellular. viscous, biologically active, non-toxic fructose polymer with a unique structure and extraordinary properties. This polysacchaxide was isolated at two different degrees of purity by. alcohol precipitation from aqueous solutions and was characterized with respect to some rheological properties and stability of viscous solutions. The effects of temperature, pH and salt concentration on the viscosity of 1-3% levan solutions were examined. The vis…
