Uses

Different sources of media describe the Uses of 54724-00-4 differently. You can refer to the following data:
1. Curdlan is a polymer produced by fermentation from the bacteria alcaligenes faecalis var. myxogenes. it forms a gel when heated in water, initially required to be dispersed and suspended in water since it is insoluble until heated. above 80°c a high-set gel that is irrevers- ible and stable to freezing is formed. a low-set gel is obtained by heating to 55–60°c and then cooling below 40°c; this gel is ther- moreversible. it is capable of gelling over ph range of 2–10. the heat gelling properties allow improved water retention in sausage and ham, improved consistency in oriental-style noodles, and provide viscosity and texture.
2. Curdlan from Alcaligenes faecalis has been used: for the stimulation of carp macrophages for regulation of differentially expressed genesto stimulate human intestinal epithelial cells for cytokine secretionto study its effect on transcriptional responses of inflammation/respiratory burst-associated genes in mouse alveolar macrophages by customized reverse transcription (RT)-PCR based arrays as a substrate in β-1,3–1,4-Glucanase activity assay

General Description

Curdlan is an insoluble natural polymer with linear structure mainly produced by Alcaligenes faecalis. It is a dietary fiber with gelatin properties.

Biochem/physiol Actions

Curdlan is used as a food additive in the food industry. It improves the elasticity and reduces the embrittling tendency of hydroxyapatite/chitosan scaffold, which aids in bone regeneration.
