With a total of 11 patents to his name, his work has had a considerable impact on various industrial applications.
Latest Patents
One of his latest inventions is an ammonia elimination liquid reagent. This reagent comprises a thermo-resistant isocitrate dehydrogenase that exhibits remarkable stability under high alkaline pH conditions. The isocitrate dehydrogenase is preferably derived from the genus Thermus. This ammonia elimination reagent can be prepared for an assay system of biological substances that generate ammonia as a reaction product. The reagent can be stored in solution and is designed to work in combination with coenzymes NAD and NADP. This novel reagent can eliminate ammonia in an extremely short time. Another significant patent is for a process for mass-producing recombinant, thermostable glutamate dehydrogenase (GLDH) at a low cost. This process involves culturing a transformant without the use of drugs such as IPTG. The invention also provides a thermostable GLDH that can utilize more stable NADH as a coenzyme in ammonia assay reagents.
