Fractionation of KMPS-2E.

<p>(A) The major fraction (KMPS-2E, t = 300∼360 min) with 0.2 M NaCl was collected for purification using Superdex 200 gel filtration chromatography; (B) the homogeneous purified KMPS-2E polysaccharide at t = 16.31 min. Its molecular weight was approximately 84,802 Da by HPGPC; (C) Infrared spectrum of KMPS-2E.
