Purificação e caracterização de uma gentioexaose obtida de botriosferana por hidrólise ácida parcial Purification and characterization of a gentiohexaose obtained from botryosphaeran by partial acid hydrolysis
<abstract language="eng">A hexa-oligosaccharide was obtained by partial acid hydrolysis from botryosphaeran, an exopolysaccharide (EPS) β(1→3; 1→6)-D-glucan type, produced by the ascomyceteous fungus Botryosphaeria rhodina. The oligosaccharide was purifie...
