About Dyadic
Dyadic International, Inc. is engaged in the development, manufacture and sale of biological products using a number of proprietary fungal strains to produce enzymes and other biomaterials, principally focused on a system for protein production based on the patented Chrysosporium lucknowense fungus, known as C1. Dyadic is applying its technologies to produce enzymes for use in converting various agricultural products (e.g. corn) and waste products (e.g. switch grass, wheat straw, sugar cane bagasse, etc.) into fermentable sugars, which can then be used in the production of traditional and cellulosic ethanol as well as other products currently derived from petroleum. Dyadic's C1 technology also is being developed to facilitate the discovery, development and large-scale production of human antibodies and other high-value therapeutic proteins. Dyadic currently sells more than 45 liquid and dry enzyme products to more than 200 industrial customers in approximately 50 countries for the textile, pulp & paper and animal feed industries.
