Title: Yoshiya Izumi: Innovator in Lignocellulose Processing
Introduction
Yoshiya Izumi is a prominent inventor based in Tokyo, Japan, known for his significant contributions to the field of lignocellulose processing. With a total of five patents to his name, Izumi has focused on developing innovative methods for producing valuable compounds from lignocellulosic materials.
Latest Patents
One of his latest patents is a process for producing xylooligosaccharide from lignocellulose pulp. This method involves enzyme-treating lignocellulose pulp with hemicellulase, filtering the resultant reaction mixture to separate a liquid fraction from the enzyme-treated pulp, and subjecting the separated liquid fraction to a permeation treatment through a separation membrane. This process effectively increases the concentration of xylooligosaccharide-lignin complex, allowing for the collection and recovery of xylooligosaccharide. Another notable patent is the process for oxygen bleaching and enzyme treating lignocellulosic pulp with liquid treatment and recovery. In this method, lignocellulose pulp is bleached using an aqueous alkali solution with oxygen, followed by treatment with hemicellulase. The liquid fraction from the enzyme treatment is separated and subjected to a penetration treatment through a separation membrane, enhancing the efficiency of the bleaching process.
