2021年12月1日 · Curdlan is a bioactive polysaccharide that is composed of 300 to 500 glucose units linked via β-1,3-glycosidic bonds. Because of its key role in intercellular communication and cellular coordination, it has great significance in bacterial communities (Zhang & Edgar, 2014).

Curdlan is an exopolysaccharide that is composed of repeating glucose monomers which are linked by β-1,3 glycosidic bonds. Curdlan was accidentally discovered by Harada and his coworkers in 1962 from Alcaligenes faecalis var myxogenes 10C3. Since curdlan has characteristic physicochemical and rheological properties, it has attained demand in ...

2021年1月1日 · Curdlan is an extracellular microbial polysaccharide and was first discovered and investigated by Harada et al. in 1964 who coined the name curdlan originating from “curdle” to describe its gelling behavior at high temperatures (Harada, Masada, Fujimori, & Maeda, 1966; Maeda, Saito, Masada, Misaki, & Harada, 1967).

2020年12月5日 · Curdlan, one kind of β-glucan polymers, was first obtained from the culture of Alcaligenes sp. in 1966. Without branching or substituents, curdlan is a linear polysaccharide composed of repeating unit of (1 → 3)-β-glucose (Fig. 1 A) and has three conformers, single helix, triple helix and random coil.

2020年7月1日 · Curdlan can form a gel with fat when used at large amounts in the products. Curdlan gel is further used in ice cream-like frozen dairy products. Curdlan participates for the retention of shape for ice cream by add 0.1–0.3% (Nishinari, 2000).

In the curdlan-starch model system, under the same frozen storage conditions, the swelling power and solubility of starch with added curdlan (MS curdlan) were significantly lower (P < 0.05) than those of the control group (MS control), especially with the addition of 0.5% curdlan. Firstly, it is likely that the strong hydrophilicity of curdlan ...

1993年1月1日 · Curdlan, a β-(1 → 3)-linked d-glucan and a thermogelable polysaccharide, was discovered in 1966.Its early history; 1, 2 early work on its production, properties, and applications; 3, 4 its physicochemical properties and its potential use in foods; 5, 6 its chemical, biochemical and microbiological properties; 7 its ultrastructure; 8 …

2021年8月1日 · Curdlan is an extracellular microbial polysaccharide with a linear β-1,3-D-glucan structure, which can be isolated from Alcaligenes faecalis var. myxogenes (Cai et al., 2020; Maeda, Saito, Masada, Misaki, & Harada, 1967). Notably, curdlan can form two kinds of gel depending on the heating temperature from a cold aqueous suspension (Cai et al ...

2009年1月1日 · Curdlan is an extracellular microbial polysaccharide and was first discovered and investigated by Harada et al. in 1964 who coined the name curdlan, derived from ‘curdle’ to describe its gelling behaviour at high temperatures. 1, 2 Curdlan is composed entirely of 1,3-β-D-glycosidic linkages, which occur widely in nature involved in cell structure and food storage in bacteria, fungi, algae ...

2021年12月1日 · Firstly, curdlan biosynthesis is discussed. Furthermore, various strategies to increase curdlan production are summarized from four aspects, including the overexpression of genes for curdlan biosynthesis, weakening/knockdown of genes from competing pathways, increasing the supply of curdlan precursors, and optimization of fermentation conditions.
