Purification and properties of a second fructan exohydrolase from the roots of Cichorium intybus
A 1-FEH II (1-fructan exohydrolase, EC 3.2.1.80) was purified from forced chicory roots (Cichorium intybus L. var. foliosum cv. Flash) by a combination of ammonium sulfate precipitation, concanavalinExpand

The metabolism of fructans in roots of Cichorium intybus during growth, storage and forcing
SUMMARY During the 1993 growing season samples from field-grown roots of chicory (Cichorium intybus L. var. foliosum cv. Flash) were analysed by ion-exchange HPLC (Dionex). We measured theExpand
