Title: Hajime Taniguchi: Innovator in Enzymatic Processes

Introduction

Hajime Taniguchi is a notable inventor based in Tsukuba, Japan. He has made significant contributions to the field of enzymatic processes, particularly in the preparation of cellobiose and cellooligosaccharides. With a total of 2 patents, his work has implications for both industrial applications and food research.

Latest Patents

Taniguchi's latest patents include a "Method for preparing cellobiose" and a "Process for enzymatic preparation of cellooligosaccharides." The method for preparing cellobiose involves using three enzymes—sucrose phosphorylase, glucose isomerase, and cellobiose phosphorylase—in the presence of orthophosphate. This innovative approach allows for high yield production of cellobiose from sucrose at low cost. The process consists of four steps, starting with the treatment of sucrose to produce fructose and glucose-1-phosphate, followed by the conversion of fructose to glucose, and finally producing cellobiose while recycling the reaction mixture.

The second patent, the process for enzymatic preparation of cellooligosaccharides, utilizes cellulase produced by microorganisms from the Genus Cellvibrio. This method employs an ultrafiltration reactor to enhance production efficiency, allowing for the accumulation of cellooligosaccharides. This process is particularly advantageous from an industrial perspective, enabling high yield production.
