Latest Patents

Kagawa's latest patents include a process for producing xylooligosaccharide from lignocellulose pulp. This process involves enzyme-treating lignocellulose pulp with hemicellulase, filtering the resultant reaction mixture, and separating a non-permeated fraction containing xylooligosaccharide-lignin complex. The method enhances the concentration of xylooligosaccharide, which is then recovered from the collected non-permeated fraction. Another notable patent is for a process of oxygen bleaching and enzyme treating lignocellulosic pulp. This method utilizes an aqueous alkali solution with oxygen to bleach the pulp while treating it with hemicellulase. The liquid fraction from the enzyme treatment is separated and subjected to a penetration treatment through a separation membrane, facilitating the bleaching process.
