Keshk 1 Biological and Physical Science Department, Institute of Environmental Studies and Research, Ain Shams University, Abbassia 11566, Cairo (Egypt) Physicochemical properties of fructan inulin produced from Acetobacter species and natural inulin were investigated. From cryscopic method, the molecular weights have been found 5010 gmol-1. for bacterial inulin and 4700 gmol-1. for natural inulin. The determination of branches for both kinds of inulin indicates that both polymers are beta-(2®1) linked polyfructan with 6.0% and 4.4% beta (2®6) branches for bacterial inulin and natural one, respectively. Moreover, the spin-lattice relaxation times (T1) for bacterial inulin was lower than that of natural one. This result indicates a great order of protons in bacterial inulin. https://www.biotech-asia.org/vol2no2/physicochemical-properties-of-fructan-inulin-produced-from-acetobacter-species/ Fructan inulin; Acetobacter species; physicho-chemical properties
