摘要：

The invertase present in roots of chicory (Cichoriun intybus) has a pH optimum of 7.5 and a MW of ca 260 000. It requires relatively high ionic strength to remove it from DEAE cellulose. Treatment of chicory root tissue with 2,4-dichlorophenoxyacetic acid gives rise to a highly active invertase with pH optimum of 5.6 and MW of ca 61 000. It is more easily removed from DEAE cellulose. © 1979.
