The present invention relates to a method for biologically producing, from seaweeds, 3,6-anhydro-L-galactitol (L-AHGol) which is a novel sugar alcohol, and agarobititol (ABol) which is in a disaccharide form having 3,6-anhydro-L-galactitol (L-AHGol) as a reducing end, by using a genetic engineering technique in GRAS strains.

Method for biologically producing sugar alcohol from agar

The present invention relates to a method for producing marine algae-derived agarotriose, and a use thereof as a prebiotic. More specifically, the present invention investigates the characteristics of agarotriose as a prebiotic which is selectively metabolized by probiotic microorganisms, thereby enabling agarotriose to be used as an anti-cancer or anti-inflammatory agent in the fields of food and pharmaceuticals, and enabling agarotriose to be obtained at high yield through efficient purification with minimal loss after enzymatic hydrolysis of a red algae-derived polysaccharide without pre-treatment.

Method for producing marine algae-derived agarotriose, and use thereof as prebiotic

The present invention relates to a preparation method for various novel fucosyl oligosaccharides and a use thereof. More specifically, the present invention allows a preparation of various novel fucosyl oligosaccharides through an enzymatic reaction with &#x3b1;-1,2-fucosyltransferase using a GDP-L-fucose donor and various glucose acceptors and an establishment of probiotic characteristics thereof, and thus has an effect of providing uses as materials for medicines, food, cosmetic products, and the like.

Preparation method for various novel fucosyl oligosaccharides and use thereof

The present invention relates to a method for chemical production of 3,6-anhydro-L-galactitol (L-AHGoI), which is a novel sugar alcohol, and agarobititol (ABol), which is a disaccharide having the same agarobititol as a reductant end thereof, from sea algae.

Method for production of sugar alcohol from red algae

The present invention relates to a use of an agarobiose or agarooligosaccharides having anticariogenic activity. More specifically, a lower concentration of agarobiose or agarooligosaccharides than the concentration of xylitol suppresses the growth ofand suppresses acid production, and thus can be used for anti-cariogenic purposes.

Use of agarobiose or agarooligosaccharide having anticariogenic activity

The present invention relates to a method for producing anhydrous galactose derived from seaweed, and provides an improved production yield rate of 3,6-anhydro-L-galactose by using microorganisms during acid treatment, neutralization, and purification after enzymatic hydrolysis, of agarose or agar.

Method for producing anhydrous galactose derived from seaweed

The present invention relates to a novel method for purifying 3,6-anhydro-L-galactose by using microorganisms and provides an effect of improving the production yield of 3,6-anhydro-L-galactose by using microorganisms during purification after enzymatic hydrolysis of agarose or agar.

Method for purifying and obtaining 3,6-anhydro-L-galactose using microorganisms

The present invention relates to a heat-resistant agarase and a monosaccharide production method using same. More particularly, in the present invention, a heat-resistant agarase may be used to produce galactose and 3,6-anhydro-L-galactose at high yield by efficiently breaking down agarose or agar without a chemical pretreatment, a neutralization process, or an agarotriose hydrolase treatment process.

Heat-resistant agarase and monosaccharide production method using same

The present invention relates to a method for preparing 3,6-anhydro-L-galactose, and use thereof. More specifically, 3,6-anhydro-L-galactose, which is a monosaccharide constituting agar, is produced in a high yield through chemical and enzymatic methods, and the physiological activities thereof such as whitening, moisturizing, antioxidant, antiinflammatory activities and the like are displayed, thereby enabling industrial use thereof.

Method for preparing 3,6-anhydro-L-galactose, and use thereof

The present invention relates to a use of 3,6-anhydro-L-galactose for preventing dental caries. More specifically, 3,6-anhydro-L-galactose inhibits the growth of oral microorganisms and exhibits anti-caries activity to inhibit the production of acids caused by the consumption of a carbon source by the oral microorganisms. Thus, 3,6-anhydro-L-galactose can be used in pharmaceuticals, food products, oral hygiene preparations, etc. for preventing, ameliorating or treating oral diseases caused by oral microorganisms, such as dental caries, gingivitis, periodontitis, oral mucosal ulcer, halitosis or xerostomia.

Use of 3,6-anhydro-L-galactose for preventing dental caries

The present invention relates to agarooligosaccharide hydrolase and a method for producing 3,6-anhydro-L-galactose and galactose from agarose by using the same. More specifically, the production yield of 3,6-anhydro-L-galactose and galactose from agarose, that is, the saccharification yield, is improved by using &#x3b2;-agarooligosaccharide hydrolase having an agarotriose hydrolytic activity.

Agarooligosaccharide hydrolase and method for producing 3,6-anhydro-L-galactose and galactose from agarose by using same

The present invention relates to a recombinant microorganism metabolizing 3,6-anhydro-L-galactose and a use thereof, and, more particularly, can produce ethanol from a recombinant microorganism expressing an enzyme group involved in a metabolic pathway of 3,6-AHG.
