Established in 1882, TOYOBO has been a leading and prominent manufacture of overall textiles in Japan.In response to the changing market environment we are expanding our product lines getting into more diversified non textile markets such as films, plastics, eloctronics-based, biochemical-related, and medical-related business.One of those reputable product lineup is TOYOBO ENZYMES, which come out of the remarkable technologies in fermentation and purification accumulated over the last several decades.


Back in the 1950s TOYOBO began working on microorganisms when seeking ways of treating waste water from one of our plants processing pulp for rayon. Scientists in our laboratories discovered that a certain type of yeast's consuming sugar in the waste water and substantially reducing the biochemical oxygen demand (BOD) level.We then filtered out the yeast to market it for animal food.As the proportion of nucleic acids in the yeast was extremely high, we separated them out and made research for use in food seasonings.In the 1960s, based on a success in commercializing uricase from Candida sp., the first of its kind, we have got focused on clinical chemistry field.Now TOYOBO excels in the market with more than 60 kinds of material enzymes for diagnostic reagents, with the finest level of quality, which gives us reputation both in the domestic and the overseas market.


In 1997, the Quality Management System of Tsuruga Biochemicals plant and Tsuruga Institute of Biotechnology has been approved in the US, UK, Germany, Holland, Australia and Japan as meeting the requirements of ISO 9001 by Lloyd's register Quality Assurance Limited(LRQA): applicable to the development and manufacture of enzymes.We are also proceeding with R&D and manufacturing activities in application of environment management system of TOYOBO Tsuruga plant which was certified in 1999 by JAB and JIC as meeting requirements of ISO 14001.
