Ulvan: A systematic review of extraction, composition and function

Algal Research, 2019
Abstract Species of green macroalgae (Chlorophyta) of the genus Ulva are edible seaweeds with a range of health promoting bioactive components. Ulva is high in dietary fibre which promotes gastrointestinal health and is linked to a reduction in the incidence of chronic diseases. The fundamental active constituent of Ulva is the soluble fibre ulvan, a

Targeting epithelial-to-mesenchymal transition of cancer cells by sulfated glycans from marine algae

Advances in Cancer Biology - Metastasis
Epithelial-mesenchymal transition (EMT) represents a process whereby an epithelial cell undergoes a series of alterations, acquiring the morphological and functional characteristics of a mesenchymal cell.

The Effect of Enhancing Ulvan's Antioxidant Properties in Supplemented Diets on Accelerating The Phenoloxidase Immune Response in White Shrimp

Hayati Journal of Biosciences
This study investigated the total phenol content (TPC) and DPPH inhibition of ulvan from Ulva lactuca, along with its supplementation effects on the specific growth rate (SGR) and phenoloxidase (PO) activity of Litopenaeus vannamei. Ulva lactuca samples

Purification and characterization of a novel glucuronan lyase from Trichoderma sp. GL2

, 2006
The filamentous fungus Trichoderma sp. GL2 produces an extracellular glucuronan lyase (GL) when grown on glucuronan as the sole carbon source. In this paper, we report the purification to electrophoretical homogeneity of this polysaccharide lyase by size

Ulvan from Ulva ohnoi macroalgae : Green extraction method and physicochemical characterization of the ulvan

Abstract Ulvan belongs to the class of sulfated heteropolysaccharide and is the main component of the seaweed Ulva ohnoi (U. ohnoi). Ulvan has a chemical structure similar to fucoidan, chondroitin sulfate, and hyaluronic acid, which are commonly used to develop drug delivery systems.

Long-type ulvan lyase in Alteromonas sp. is a major enzyme involved in degradation of ulvan extracted from Ulva ohnoi

, 2017
Abstract: Ulvan is one of the key sulfated polysaccharide components constituting the cell walls of green algae, Ulva. A little study has been performed so far on the ulvan degrading bacterial enzymes. In order to utilize ulvan effectively by breaking down to oligosaccharides and monosaccharide, we have studied ulvan-degrading bacterial enzymes.
