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 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: Disclosed herein are a method, an apparatus, and a storage medium for image encoding/decoding using filtering. The image encoding method and the image decoding method perform classification on a classification unit of a target image, and perform filtering that uses a filter on the classification unit. A classification index of the classification unit is determined, and the classification index indicates a filter to be used for filtering on the classification unit, among multiple filters. The classification index is determined by various coding parameters, such as an encoding mode of the target block and an encoding mode of a neighboring block adjacent to the target block.

Abstract: The present invention relates to a method for quantifying 3,6-anhydro-L-galactose using high-performance liquid chromatography and a differential refractometric index detector, whereby L-AHG and D-galactose, which are saccharification products of agarose or agar, can be independently quantified by controlling the separation conditions of the high-performance liquid chromatography/differential refractive index detector, even though the two materials are difficult to separate due to having similar molecular weights and structures.

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.
