The chemical and gelling properties of ulvan from blade and filamentous Ulva of New Zealand

See chapter 3 of the thesis for full details. The characteristics of ulvan from different Ulva species collected from the Bay of Plenty, Aotearoa New Zealand were compared. The chemical characteristics of ulvan from blade (U. australis, U. rigida, U. sp. B, and Ulva sp.) and filamentous (U. flexuosa, U. compressa, U. prolifera, and U. ralfsii) Ulva species were assessed through elemental, sulfate and ash quantification, size exclusion chromatography with multi-angle light scattering detector, constituent sugar analysis with high performance anion exchange chromatography with pulsed amperometric detection, and nuclear magnetic resonance spectroscopy. Rheology characteristics of ulvans were assessed through dynamic rheological measurements using a single-head hybrid rheometer. The full methodologies will be available in the author's thesis (Chapter 3) from the Related Publications link below.

B及Ulva sp.）和丝状（U. flexuosa、U. compressa、U. prolifera及U. ralfsii）石莼属物种来源的石莼聚糖的化学特征进行表征。此外，本研究采用单头混合流变仪开展动态流变测试，对石莼聚糖的流变学特征进行表征。完整实验方法可通过下方「相关出版物」链接获取作者学位论文的第3章内容。
