Abstract: The present invention relates to a novel beta-glucosidase for producing glucose and a laminarioligosaccharide from seaweed. More particularly, the present invention may produce glucose from a beta-glucosidase exhibiting transglycosylase activity while showing exo-type glucanase activity against beta-glucan, as well as produce a laminarioligosaccharide by exhibiting transglycosylase activity against laminarin under different reaction conditions.

Abstract: 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.

Abstract: 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.

Abstract: 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 of Streptococcus mutans and suppresses acid production, and thus can be used for anti-cariogenic purposes.

Abstract: The present invention relates to a method for producing anhydrous galactose derived from seaweed, and provides an improved production yield of 3,6-anhydro-L-galactose (AHG) from agarose or agar through multiple steps involving acid hydrolysis of agar or agarose for producing agarobiose, neutralization of the acid hydrolysate, and purification of AHG using a microorganism metabolizing galactose after enzymatic hydrolysis of agarobiose.
