Abstract

The exopolysaccharide (EPS) separated from the entomopathogenic fungus Metarhizium anisopliae was determined by gel permeation chromatography to be homogeneous. The high-performance anion-exchange chromatography with pulsed-amperometric detection (HPAE-PAD) showed a content of monosaccharides D-galactosamine and D-fucose at a molar ratio of about 2:1. The results obtained from Fourier transform-infrared spectroscopy (FT-IR) and second derivative FT-IR spectrum confirmed the proposed structure.
