Transfructosidation in extracts of the tubers of Helianthus tuberosus L.

The action of hydrolytic enzyme system from Helianthus tuberosus L. on carbohydrates present in the tubers.

Localization of the Enzymes of Fructan Metabolism in Vacuoles Isolated by a Mechanical Method from Tubers of Jerusalem Artichoke (Helianthus tuberosus L.).

Vacuoles isolated by a mechanical slicing method from developing tubers of Jerusalem artichoke (Helianthus tuberosus L.) contain activities of the two principal enzymes responsible for fructan synthesis: sucrose-sucrose fructosyl transferase and fructan-fructan fructosyl transferase. Both enzymes are associated with the vacuolar sap and not with the tonoplast. In vacuoles isolated from dormant ...

Microsoft Word - Acta_TA_10(4)_2011.docx

Introduction. Jerusalem artichoke (Helianthus tuberosus L.) is grown primarily for its edible tubers, which were first cultivated by native Americans before the arrival of the Europeans. Unlike most tubers, but in common with other members of the Asteraceae, the tubers store fructans instead of starch. Fructans are non-digestible carbohydrates considered functional food ingredients because they...

Secretion of Specific Cytotoxic Products by Plant Storage Organs after Wound-Desiccation Stress

After a wound-desiccation stress, plant tissues can secrete products that have specific cytotoxicity against melanoma B16 cells. Healthy plant or animal cells were not susceptible to these products. Secretion of the active product varied with the plant species and the plant organs. The secretion of tubers of yam (Dioscorea cayenensis Lam), cassava (Manihot esculenta), Jerusalem artichoke (Helia...

Economically Viable Components from Jerusalem Artichoke (Helianthus tuberosus L.) in a Biorefinery Concept

Biorefinery applications are receiving growing interest due to climatic and waste disposal issues and lack of petroleum resources. Jerusalem artichoke (Helianthus tuberosus L.) is suitable for biorefinery applications due to high biomass production and limited cultivation requirements. This paper focuses on the potential of Jerusalem artichoke as a biorefinery crop and the most viable products ...
