Title: Yutaka Shimura: Innovator in Microbial Technology and Heat-Sensitive Materials
Introduction
Yutaka Shimura is a notable inventor based in Tokyo, Japan. He has made significant contributions to the fields of microbial technology and heat-sensitive materials. With a total of 3 patents, his work has had a considerable impact on various industries.
Latest Patents
One of Shimura's latest patents involves a process for treating yeast with B-1, 3-glucanase to produce microorganism cells. This innovative method allows yeast cells, such as Saccharomyces or Candida, to be treated with an alkaline aqueous solution while being heated and stirred. The treatment enables the cells to function as microcapsules by rapidly absorbing a large amount of hydrophobic liquid. The alkaline treatment is ideally conducted at a pH of at least 8 for a minimum of one hour at temperatures ranging from 20 to 100 degrees Celsius. Additionally, a preferred embodiment of enzyme treatment utilizes β-1,3-glucanase for about 30 minutes to 5 hours at a pH of 4-9 and temperatures between 30 to 60 degrees Celsius. This process effectively dissolves the cell walls of the yeast while maintaining sufficient strength to enclose hydrophobic liquids.
Another significant patent by Shimura is related to a heat-sensitive recording material. This material comprises a color-forming agent made from an aromatic isocyanate compound and an imino compound, along with a phenol compound. The resulting recording material demonstrates excellent storability for both images and non-image areas.
