Fig. 1. Effect of mutastein on the formation of artificial plaque on Nichrome-steel wires by Streptococcus mutans 671 5. Experimental conditions were described in the text. 1; Control, 2; 15 ^g/ml mutastein, 3; 50 ^g/ml mutastein. It is believed to be a significant step for the induction of dental caries that cariogenic Streptococcus mutans synthesizes adhesive, insoluble glucan from sucrose an...

Silkworm β-1,3-glucan recognition protein (βGRP) tightly and specifically associates with β-1,3-glucan. We report here an affinity purification system named the 'GRP system', which uses the association between the β-1,3-glucan recognition domain of βGRP (GRP-tag), as an affinity tag, and curdlan beads. Curdlan is a water-insoluble β-1,3-glucan reagent, the low cost of which (about 100 JPY/g) al...

objective: in recent decades, β-glucans have been used as important complementary and alternative medicines for numerous immunocompromised individuals and those with end stage of cancer terminal. the most active form of β-glucans is β(1,3)d-glucan and its  most common source is cell wall of candida albicans. recently it has been introduced as a nano particle design to be used as a carrier for d...

the present experiment was undertaken to study the effect of different dosages of β-glucan on the growth, survival and physiological responses in juvenile striped catfish ( pangasianodon hypophthalmus ). over nine weeks of feeding fish with a diet containing 0, 0.5, 1 and 2% β-glucan (as control, g1, g2 and g3 group, respectively), some blood parameters such as serum lysozyme activity, total pr...

BACKGROUND β-1,3-Glucanases catalyze the hydrolysis of glucan polymers containing β-1,3-linkages. These enzymes are of great biotechnological, agricultural and industrial interest. The applications of β-1,3-glucanases is well established in fungal disease biocontrol, yeast extract production and wine extract clarification. Thus, the identification and characterization of novel β-1,3-glucanases ...

Glutaraldehyde-crosslinked α-casein polymers with molecular masses of 1-5×10(5) were found to inhibit adhesive insoluble glucan formation catalyzed by glucan synthases from Streptococcus sobrinus B13, a cariogenic oral bacterium. Of the three subcomponents of the glucan synthases tested, primer-dependent insoluble glucan synthase was inhibited specifically by the M r~2.7×10(5) polymer at a conc...

The β-glucanase enzyme is an protein that can hydrolyze β-glucan, one of the main components fungal cell wall. This produced by several bacteria, which B. subtilis. three-dimensional (3D) structure proteins necessary to understand their properties and functions proteins. Enzyme be analyzed for function using in silico method. study aims detect gene from subtilis W3.15 analyze it methods this re...

Soybean insoluble fractions recovered from aqueous extraction processing (AEP) and enzyme-assisted AEP (EAEP) of full-fat soybean flakes (FFSF) and extruded FFSF were evaluated as a feedstock for the production of fermentable sugars using enzymes. Among the four insoluble fractions (AEP FFSF, EAEP FFSF, AEP extruded FFSF and EAEP extruded FFSF), the composition analysis revealed that the one re...

The structure of the extracellular polysaccharide (water-insoluble D-glucan) from an anaerobic, Gram-positive coccus organism (Streptococcus) has been investigated. Acid hydrolysis of the methylated glucan yielded 2,3,4,6-tetra-, 2,3,4-tri-, 2,4,6-tri, and 2,4-di-O-methyl-D-glucose in the molar ratios of 1.13:3.99:1.00:1.02, indicating that the D-glucan has a branched structure containing (1 le...
