Agar from Gracilaria gracilis (Gracilariales, Rhodophyta) of the Patagonic coast of Argentina - Content, structure and physical properties

Milled summer thalli of Gracilaria gracilis from Argentina were sequentially extracted with water at room temperature (RTW1-3), 70 °C (W701-3) and 90 °C (W901-2). Both W701 and W901 consisted of high molecular weight polysaccharides (ca. 540,000 Da), but polydispersity was higher for the major produ...
