Reaction using biocatalyst and device for said reaction
专利汇可以提供Reaction using biocatalyst and device for said reaction专利检索，专利查询，专利分析的服务。并且PURPOSE: To make possible to directly use biocatalyst without depression of activity accompanying immobilization by separating reacted solution of substrate and biocatalyst to the biocatalyst and a liquid containing substrate and reacted product by ultrafiltration membrane, the returning the former to reaction tank, etc.
CONSTITUTION: Substrate is reacted with biocatalyst in aqueous solution in reaction tank 1 and the reacted solution is sent to ultrafilter 2. The reacted solution is separated to the biocatalyst and a solution containing reacted product and residual substrate by ultrafiltration membrane in the ultrafilter, then the former is returned to the reaction tank 1 and the latter is sent to crystallizing tank 3. The reacted product is crystallized in the crystallizing tank 3 and a solution containing the crystallized substance and the substrate is sent to a filter 4. Then, filtered solution containing the substrate is returned to the reaction tank 1 and crystallized reacted product is accumulated in the filter 4. Said process is preferably performed for transaminase as biocatalyst, phenylpyruvic acid and L-asparagine acid as substrate and L-phenylalanine as reacted product.
