System for directionally converting dipeptide through continuous flow membrane enzyme coupling

Abstract

The invention provides a system for directionally converting dipeptide through continuous flow membrane enzyme coupling, and relates to the technical field of continuous flow membrane enzyme coupling. According to the system for directionally converting the dipeptide through continuous flow membrane enzyme coupling, amino acid raw materials in the first stirring tank and the second stirring tank are mixed and then conveyed from the bottommost membrane enzyme coupling reaction unit, and biological enzyme liquid in the biological enzyme tank is conveyed from the other end of the bottommost membrane enzyme coupling reaction unit, so a continuous flow mixing reaction of the amino acid and the biological enzyme is formed; the plurality of membrane enzyme coupling reaction units which are arranged up and down form a long channel, so the contact area and the contact time among raw materials are increased, and a product is intercepted by a nanofiltration membrane in the membrane enzyme coupling reaction unit in time; the incompletely reacted amino acid raw material and the biological enzyme are circulated through the liquid storage tank and the return pipe and then enter the membrane enzyme coupling reaction unit for continuous reaction until the completely converted dipeptide is completely intercepted, so the conversion rate and the yield of the dipeptide product are improved.

Description

technical field [0001] The invention relates to the technical field of continuous flow membrane enzyme coupling, in particular to a continuous flow membrane enzyme coupling directional conversion dipeptide system. Background technique [0002] In order to solve the above shortcomings of the traditional enzymatic hydrolysis reaction, many scholars have begun to study the enzymatic hydrolysis-membrane separation coupling reaction technology (referred to as "enzyme-membrane coupling technology") in recent years, that is, the reactor and the separation membrane are connected by means of a circulating pump. At the same time as the enzymatic hydrolysis reaction, the enzymatic hydrolyzate that has reached the molecular weight is separated from the reaction system in time by membrane separation, and at the same time, the reaction substrate is continuously replenished at a certain speed until the remaining reaction residue in the reaction system seriously blocks the separation membran...

AI Technical Summary

Problems solved by technology

At present, there are few reports on the continuous flow membrane enzyme-coupled directional conversion system of dipeptides. Further research is still needed to improve the conversion rate and yield of dipeptide products by continuously reacting unreacted amino acid raw materials with biological enzymes.
