A process for producing an alginate oligomer by digesting an alginate derivative with an enzyme and a method for producing an alginate oligosaccharide

摘要

(Purpose) It is intended to provide a low molecular weight alginate polymer and a production method of alginate oligosaccharide, a development of a fish parasitic scutica insecticide, and a novel production method of an electric insecticide.;(Composition) After dissolving alginate in a beaker, the cellulase was added to the beaker while it was warmed to 45C, stirred, and reacted. After a certain period of time, the enzyme activity was stopped and the filtrate was concentrated and dried. A low molecular weight alginate and an alginate oligosaccharide derivative are obtained. It is recommended that a bath be made in a fish tank infested with a fish parasite, Scutica, mixed with 0.1% to 0.01% by weight of the sea water in the growing tank, and then mixed with 0.1-0.01 wt% do.
