Resumen
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.
