Abstract
The application belongs to the technical field of bioengineering, and particularly relates to a sphingan oligosaccharide and a preparation method and application thereof. The application provides a sphingan oligosaccharide, the main chain structure of which is beta-L-Rhap-(1→3)-beta-D-Glcp-(1→4)-beta-D-GlcpA, and the sphingan oligosaccharide is obtained by degrading sphingan (Welan gum, gellan gum and diutan gum) by sphingan degrading enzyme SpnR and then purified by liquid chromatography. The sphingan oligosaccharide prepared by the preparation method has mild reaction conditions and is simple to separate. The sphingan oligosaccharide prepared by the application has good plant growth promoting ability and intestinal probiotic effect, and can be used in the fields of agriculture, food, health products and the like, and the application of the sphingan and the sphingan oligosaccharide is expanded.
