dc.description.abstract | A (1→3)-β-D-Glucan produced by Lactobacillus suebicus CUPV221 strain was
investigated by tapping mode atomic force microscopy (TM-AFM), to compare its
supramolecular structure and conformation with two commercial polysaccharides: curdlan
and scleroglucan. It was found that the β-D-Glucan was a (1→3)(1→2)-β-D-Glucan and at
room temperature formed three-dimensional networks by entanglements between strands, as
does scleroglucan. However, (1→3)(1→2)-β-D-Glucan strands seemed to be more stiff than
those of scleroglucan. It was also observed that curdlan samples deposited from 5 mM NaOH
aqueous solution showed supermolecular assemblies, recognized in the literature as micelles,
which are controlled by hydrophobic hydration. The (1→3)(1→2)-β-D-Glucan in alkaline
aqueous solutions produced different supramolecular structures depending on pH, and at
0.4 M NaOH (pH 13.16), denaturation took place. After neutralizing the alkaline solution
with HCl, the formation of short linear, circular, and hairpin structures was observed. | es_ES |
