Title: The Innovations of Toshihiko Higashi

Introduction

Toshihiko Higashi is a notable inventor based in Hachioji, Japan. He has made significant contributions to the field of biotechnology, particularly in the development of enzymes and microbial rennet. With a total of 2 patents, his work has had a considerable impact on various applications in food technology.

Latest Patents

Higashi's latest patents include a protease with low thermostability derived from Mucor pusillus. This invention involves creating a mutant fungus strain that produces a protease with low thermostability and low productivity. The gene coding for this mutant enzyme is isolated from the strain, and a promoter that functions in yeast is ligated to the gene. This plasmid is then introduced into yeast, which is cultured to produce the mutant enzyme. Additionally, he has developed a method for increasing the milk coagulating activity of microbial rennet obtained from Mucor pusillus microorganisms. This method involves acylating the microbial rennet in an aqueous medium, resulting in improved microbial rennet with a low PA/MCA index and a high MCA index.
